I'm having trouble with using 'requests' module on my Mac. I use python34 and I installed 'requests' module via pip. I can verify this via running installation again and it'll show me that module is already installed.
15:49:29|mymac [~]:pip install requests
Requirement already satisfied (use --upgrade to upgrade): requests in /opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages
Although I can import 'requests' module via interactive Python interpreter, trying to execute 'import requests' in PyCharm yields error 'No module named requests'. I checked my PyCharm Python interpreter settings and (I believe) it's set to same python34 as used in my environment. However, I can't see 'requests' module listed in PyCharm either.
It's obvious that I'm missing something here. Can you guys advise where should I look or what should I fix in order to get this module working? I was living under impression that when I install module via pip in my environment, PyCharm will detect these changes. However, it seems something is broken on my side ...
In my case, using a pre-existing virtualenv did not work in the editor - all modules were marked as unresolved reference (running naturally works, as this is outside of the editor's config, just running an external process (not so easy for debugging)).
Turns out PyCharm did not add the site-packages directory... the fix is to manually add it.
On Pycharm professional 2022.3
Open File -> Settings -> Python Interpreter, open the drop-down and pick "Show All..." (to edit the config) (1), right click your interpreter (2), click "Show Interpreter Paths" (3).
In that screen, manually add the "site-packages" directory of the virtual environment [looks like .../venv/lib/python3.8/site-packages (4) (I've added the "Lib" also, for a good measure); once done and saved, they will turn up in the interpreter paths.
The other thing that won't hurt to do is select "Associate this virtual environment with the current project", in the interpreter's edit box.
If you are using PyCharms CE (Community Edition), then click on:
File->Default Settings->Project Interpreter
See the + sign at the bottom, click on it. It will open another dialog with a host of modules available. Select your package (e.g. requests) and PyCharm will do the rest.
This issue arises when the package you're using was installed outside of the environment (Anaconda or virtualenv, for example). In order to have PyCharm recognize packages installed outside of your particular environment, execute the following steps:
Go to
Preferences -> Project -> Project Interpreter -> 3 dots -> Show All ->
Select relevant interpreter -> click on tree icon Show paths for the selected interpreter
Now check what paths are available and add the path that points to the package installation directory outside of your environment to the interpreter paths.
To find a package location use:
$ pip show gym
Name: gym
Version: 0.13.0
Summary: The OpenAI Gym: A toolkit for developing and comparing your reinforcement learning agents.
Home-page: https://github.com/openai/gym
Author: OpenAI
Author-email: gym#openai.com
License: UNKNOWN
Location: /usr/local/lib/python3.7/site-packages
...
Add the path specified under Location to the interpreter paths, here
/usr/local/lib/python3.7/site-packages
Then, let indexing finish and perhaps additionally reopen your project.
Open python console of your pyCharm. Click on Rerun.
It will say something like following on the very first line
/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 /Applications/PyCharm.app/Contents/helpers/pydev/pydevconsole.py 52631 52632
in this scenario pyCharm is using following interpretor
/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7
Now fire up console and run following command
sudo /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 -m pip install <name of the package>
This should install your package :)
Pycharm is unable to recognize installed local modules, since python interpreter selected is wrong. It should be the one, where your pip packages are installed i.e. virtual environment.
I had installed packages via pip in Windows. In Pycharm, they were neither detected nor any other Python interpreter was being shown (only python 3.6 is installed on my system).
I restarted the IDE. Now I was able to see python interpreter created in my virtual environment. Select that python interpreter and all your packages will be shown and detected. Enjoy!
Using dual python 2.7 and 3.4 with 2.7 as default, I've always used pip3 to install modules for the 3.4 interpreter, and pip to install modules for the 2.7 interpreter.
Try this:
pip3 install requests
This is because you have not selected two options while creating your project:-
** inherit global site packages
** make available to all projects
Now you need to create a new project and don't forget to tick these two options while selecting project interpreter.
The solution is easy (PyCharm 2021.2.3 Community Edition).
I'm on Windows but the user interface should be the same.
In the project tree, open External libraries > Python interpreter > venv > pyvenv.cfg.
Then change:
include-system-site-packages = false
to:
include-system-site-packages = true
Before going further, I want to point out how to configure a Python interpreter in PyCharm: [SO]: How to install Python using the "embeddable zip file" (#CristiFati's answer). Although the question is for Win, and has some particularities, configuring PyCharm is generic enough and should apply to any situation (with minor changes).
There are multiple possible reasons for this behavior.
1. Python instance mismatch
Happens when there are multiple Python instances (installed, VEnvs, Conda, custom built, ...) on a machine. Users think they're using one particular instance (with a set of properties (installed packages)), but in fact they are using another (with different properties), hence the confusion. It's harder to figure out things when the 2 instances have the same version (and somehow similar locations)
Happens mostly due to environmental configuration (whichever path comes 1st in ${PATH}, aliases (on Nix), ...)
It's not PyCharm specific (meaning that it's more generic, also happens outside it), but a typical PyCharm related example is different console interpreter and project interpreter, leading to confusion
The fix is to specify full paths (and pay attention to them) when using tools like Python, PIP, .... Check [SO]: How to install a package for a specific Python version on Windows 10? (#CristiFati's answer) for more details
This is precisely the reason why this question exists. There are 2 Python versions involved:
Project interpreter: /Library/Frameworks/Python.framework/Versions/3.4
Interpreter having the Requests module: /opt/local/Library/Frameworks/Python.framework/Versions/3.4
well, assuming the 2 paths are not somehow related (SymLinked), but in latest OSX versions that I had the chance to check (Catalina, Big Sur, Monterey) this doesn't happen (by default)
When dealing with this kind of error, it always helps (most likely) displaying the following information (in a script or interpreter console):
import os
import sys
print(sys.executable)
print(sys.version)
print(os.getcwd())
print(getattr(os, "uname", lambda: None)())
print(sys.path)
2. Python's module search mechanism misunderstanding
According to [Python.Docs]: Modules - The Module Search Path:
When a module named spam is imported, the interpreter first searches for a built-in module with that name. These module names are listed in sys.builtin_module_names. If not found, it then searches for a file named spam.py in a list of directories given by the variable sys.path. sys.path is initialized from these locations:
The directory containing the input script (or the current directory when no file is specified).
PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH).
The installation-dependent default (by convention including a site-packages directory, handled by the site module).
A module might be located in the current dir, or its path might be added to ${PYTHONPATH}. That could trick users into making them believe that the module is actually installed in the current Python instance ('s site-packages). But, when running the current Python instance from a different dir (or with different ${PYTHONPATH}) the module would be missing, yielding lots of headaches
For a fix, check [SO]: How PyCharm imports differently than system command prompt (Windows) (#CristiFati's answer)
3. A PyCharm bug
Not very likely, but it could happen. An example (not related to this question): [SO]: PyCharm 2019.2 not showing Traceback on Exception (#CristiFati's answer)
To fix, follow one of the options from the above URL
4. A glitch
Not likely, but mentioning anyway. Due to some cause (e.g.: HW / SW failure), the system ended up in an inconsistent state, yielding all kinds of strange behaviors
Possible fixes:
Restart PyCharm
Restart the machine
Recreate the project (remove the .idea dir from the project)
Reset PyCharm settings: from menu select File -> Manage IDE Settings -> Restore Default Settings.... Check [JetBrains]: Configuring PyCharm settings or [JetBrains.IntelliJ-Support]: Changing IDE default directories used for config, plugins, and caches storage for more details
Reinstall PyCharm
Needless to say that the last 2 options should only be attempted as a last resort, and only by experts, as they might mess up other projects and not even fix the problem
Not directly related to the question, but posting:
[SO]: Run / Debug a Django application's UnitTests from the mouse right click context menu in PyCharm Community Edition? (a PyCharm related investigation from a while ago)
[SO]: ImportError: No module named win32com.client (#CristiFati's answer)
If you go to pycharm project interpreter -> clicked on one of the installed packages then hover -> you will see where pycharm is installing the packages. This is where you are supposed to have your package installed.
Now if you did sudo -H pip3 install <package>
pip3 installs it to different directory which is /usr/local/lib/site-packages
since it is different directory from what pycharm knows hence your package is not showing in pycharm.
Solution: just install the package using pycharm by going to File->Settings->Project->Project Interpreter -> click on (+) and search the package you want to install and just click ok.
-> you will be prompted package successfully installed and you will see it pycharm.
If any one faces the same problem that he/she installs the python packages but the PyCharm IDE doesn't shows these packages then following the following steps:
Go to the project in the left side of the PyCharm IDE then
Click on the venv library then
Open the pyvenv.cfg file in any editor then
Change this piece of code (include-system-site-packages = flase) from false to true
Then save it and close it and also close then pycharm then
Open PyCharm again and your problem is solved.
Thanks
This did my head in as well, and turns out, the only thing I needed to do is RESTART Pycharm. Sometimes after you've installed the pip, you can't load it into your project, even if the pip shows as installed in your Settings. Bummer.
For Anaconda:
Start Anaconda Navigator -> Enviroments -> "Your_Enviroment" -> Update Index -> Restart IDE.
Solved it for me.
After pip installing everything I needed. I went to the interpreter and re-pointed it back to where it was at already.
My case: python3.6 in /anaconda3/bin/python using virtualenv...
Additionally, before I hit the plus "+" sign to install a new package. I had to deselect the conda icon to the right of it. Seems like it would be the opposite, but only then did it recognize the packages I had/needed via query.
In my case the packages were installed via setup.py + easy_install, and the they ends up in *.egg directories in site_package dir, which can be recognized by python but not pycharm.
I removed them all then reinstalled with pip install and it works after that, luckily the project I was working on came up with a requirements.txt file, so the command for it was:
pip install -r ./requirement.txt
I just ran into this issue in a brand new install/project, but I'm using the Python plugin for IntelliJ IDEA. It's essentially the same as PyCharm but the project settings are a little different. For me, the project was pointing to the right Python virtual environment but not even built-in modules were being recognized.
It turns out the SDK classpath was empty. I added paths for venv/lib/python3.8 and venv/lib/python3.8/site-packages and the issue was resolved. File->Project Structure and under Platform Settings, click SDKs, select your Python SDK, and make sure the class paths are there.
pip install --user discord
above command solves my problem, just use the "--user" flag
I fixed my particular issue by installing directly to the interpreter. Go to settings and hit the "+" below the in-use interpreter then search for the package and install. I believe I'm having the issue in the first place because I didn't set up with my interpreter correctly with my venv (not exactly sure, but this fixed it).
I was having issues with djangorestframework-simplejwt because it was the first package I hadn't installed to this interpreter from previous projects before starting the current one, but should work for any other package that isn't showing as imported. To reiterate though I think this is a workaround that doesn't solve the setup issue causing this.
If you are having issues with the underlying (i.e. pycharm's languge server) mark everything as root and create a new project. See details: https://stackoverflow.com/a/73418320/1601580 this seems to happy to me only when I install packages as in editable mode with pip (i.e. pip install -e . or conda develop). Details: https://stackoverflow.com/a/73418320/1601580
--WINDOWS--
if using Pycharm GUI package installer works fine for installing packages for your virtual environment but you cannot do the same in the terminal,
this is because you did not setup virtual env in your terminal, instead, your terminal uses Power Shell which doesn't use your virtual env
there should be (venv) before you're command line as shown instead of (PS)
if you have (PS), this means your terminal is using Power Shell instead of cmd
to fix this, click on the down arrow and select the command prompt
select command prompt
now you will get (venv) and just type pip install #package name# and the package will be added to your virtual environment
On windows I had to cd into the venv folder and then cd into the scripts folder, then pip install module started to work
cd venv
cd scripts
pip install module
instead of running pip install in the terminal -> local use terminal -> command prompt
see below image
pycharm_command_prompt_image
In your pycharm terminal run pip/pip3 install package_name
I need to create new virtual environment in PyCharm. There are already some files in the folder.
This is how my project looks like:
I want to create venv in heureka-negativni-reviews
I try: File -> New project.
I switch this settings:
to have Python 3.10 as an interpreter and to create venv in heureka-negativni-reviews
But when I click on create, I got:
EDIT:
I found that I am not able to select Python 3.10 as an interpreter:
But I cannot click OK when I select Python 3.10:
What is the problem, please?
Now we see the reason, why your IDE is not able to create your venv, since the command line isn't either, which is the set of commands your IDE typically uses.
The pip and pip3 belongs to python3.8 and that is another problem, if you want to install python packages for python 3.10, which isn't possible this time without system invention.
Also your python setup seems to be messed.
/home/vojta/Desktop/INTERNET_HANDEL/HEUREKA/heureka-negativni-reviews/venv/bin/python
seems not to be a general system path. It looks that you built your own version of python and installed it by a specific prefix. Installing python correctly is off the topic here.
There are different installers for different platforms which provide install instruction inside their archives.
Before doing this, it's recommended to clean up your messed installation first.
You may find information here and there.
It could also be, that you are trying to create another venv from within an already sourced venv. Such kind of composed venvs can lead to confusion and that would explain your path above a bit more, which contains /venv/.
Also manually remove all your custom python versions from your /home/vojta/ directory, like $ rm -r /home/vojta/Desktop/INTERNET_HANDEL
First ensure that the Python interpreter is added to the list available (by adding as an 'Existing environment').
Then add a venv via link
Then drag and drop your existing files to the venv directory.
before with venv after drag and drop
In PyCharm, I've added the Python environment /usr/bin/python. However,
from gnuradio import gr
fails as an undefined reference. However, it works fine in the Python interpreter from the command line.
GNURadio works fine with python outside of Pycharm. Everything is installed and configured how I want it.
Gnuradio is located at /usr/local/lib/python2.7/site-packages/gnuradio
Also:
PYTHONPATH=/usr/local/lib/python2.7/site-packages:/usr/local/lib/python2.7/site-packages/gnuradio
Adding a Path
Go into File → Settings → Project Settings → Project Interpreter.
Then press configure interpreter, and navigate to the "Paths" tab.
Press the + button in the Paths area. You can put the path to the module you'd like it to recognize.
But I don't know the path..
Open the python interpreter where you can import the module.
>> import gnuradio
>> gnuradio.__file__
"path/to/gnuradio"
Most commonly you'll have a folder structure like this:
foobarbaz/
gnuradio/
__init__.py
other_file.py
You want to add foobarbaz to the path here.
You should never need to modify the path directly, either through environment variables or sys.path. Whether you use the os (ex. apt-get), or pip in a virtualenv, packages will be installed to a location already on the path.
In your example, GNU Radio is installed to the system Python 2's standard site-packages location, which is already in the path. Pointing PyCharm at the correct interpreter is enough; if it isn't there is something else wrong that isn't apparent. It may be that /usr/bin/python does not point to the same interpreter that GNU Radio was installed in; try pointing specifically at the python2.7 binary. Or, PyCharm used to be somewhat bad at detecting packages; File > Invalidate Caches > Invalidate and Restart would tell it to rescan.
This answer will cover how you should set up a project environment, install packages in different scenarios, and configure PyCharm. I refer multiple times to the Python Packaging User Guide, written by the same group that maintains the official Python packaging tools.
The correct way to develop a Python application is with a virtualenv. Packages and version are installed without affecting the system or other projects. PyCharm has a built-in interface to create a virtualenv and install packages. Or you can create it from the command line and then point PyCharm at it.
$ cd MyProject
$ python2 -m virtualenv env
$ . env/bin/activate
$ pip install -U pip setuptools # get the latest versions
$ pip install flask # install other packages
In your PyCharm project, go to File > Settings > Project > Project Interpreter. If you used virtualenvwrapper or PyCharm to create the env, then it should show up in the menu. If not, click the gear, choose Add Local, and locate the Python binary in the env. PyCharm will display all the packages in the selected env.
In some cases, such as with GNU Radio, there is no package to install with pip, the package was installed system-wide when you install the rest of GNU Radio (ex. apt-get install gnuradio). In this case, you should still use a virtualenv, but you'll need to make it aware of this system package.
$ python2 -m virtualenv --system-site-packages env
Unfortunately it looks a little messy, because all system packages will now appear in your env, but they are just links, you can still safely install or upgrade packages without affecting the system.
In some cases, you will have multiple local packages you're developing, and will want one project to use the other package. In this case you might think you have to add the local package to the other project's path, but this is not the case. You should install your package in development mode. All this requires is adding a setup.py file to your package, which will be required anyway to properly distribute and deploy the package later.
Minimal setup.py for your first project:
from setuptools import setup, find_packages
setup(
name='mypackage',
version='0.1',
packages=find_packages(),
)
Then install it in your second project's env:
$ pip install -e /path/to/first/project
For me, it was just a matter of marking the directory as a source root.
Add path in PyCharm 2017
File -> Settings (or Ctrl+Alt+S) -> Project -> Project Interpreter
Show all
Select bottom icon on the right side
Click on the plus button to add new path to your module
My version is PyCharm Professional edition 3.4, and the Adding a Path part is different.
You can go to "Preferences" --> "Project Interpreter". Choose the tool button at the right top corner.
Then choose "More..." --> "Show path for the selected interpreter" --> "Add". Then you can add a path.
DON'T change the interpreter path.
Change the project structure instead:
File -> Settings -> Project -> Project structure -> Add content root
In PyCharm 2020.1 CE and Professional, you can add a path to your project's Python interpreter by doing the following:
1) Click the interpreter in the bottom right corner of the project and select 'Interpreter Settings'
2) Click the settings button to the right of the interpreter name and select 'Show All':
3) Make sure your project's interpreter is selected and click the fifth button in the bottom toolbar, 'show paths for the selected interpreter':
4) Click the '+' button in the bottom toolbar and add a path to the folder containing your module:
For PyCharm Community Edition 2016.3.2 it is:
"Project Interpreter" -> Top right settings icon -> "More".
Then on the right side there should be a packages icon. When hovering over it it should say "Show paths for selected interpreter". Click it.
Then click the "Add" button or press "alt+insert" to add a new path.
As quick n dirty fix, this worked for me:
Adding this 2 lines before the problematic import:
import sys
sys.path.append('C:\\Python27\\Lib\site-packages')
On Project Explorer, you can right click on the folder where the module is contained and set as 'Source'.
It will be parsed in the Index for code completion as well as other items.
I'm new to PyCharm (using 2018.3.4 CE) and Python so I rotely tried to follow each of the above suggestions to access the PIL (Pillow) package which I knew was in system-site-packages. None worked. I was about to give up for the night when I happened to notice the venv/pyvenv.cfg file under my project in the Project Explorer window. I found the line "include-system-site-packages = false" in that file and so I changed it to "true". Problem solved.
In my PyCharm 2019.3, select the project, then File ---> Settings, then Project: YourProjectName, in 'Project Interpreter', click the interpreter or settings, ---> Show all... ---> Select the current interpreter ---> Show paths for the selected interpreter ---> then click 'Add' to add your library, in my case, it is a wheel package
For me there is also another issue. If you try to add a folder that in the past had a .idea folder, but your current project has it's own .idea folder your pycharm might get confused for some reason -- even if you have the right python/conda env. For me deleting the .idea folder of the other project fixed the confusion that it could find the obviously correctly installed pkgs. Then it was it was able to find them in the pycharm editor GUI snf stopped underlyinging them in red.
Download anaconda

I am trying to use a virtual environment (venv) as the project interpreter for a PyCharm project. The virtual environment is called venvtest and is set up within the PyCharm project directory. That is, the project directory is /Users/gitanjali/Desktop/plot_bridges2 and the path to the virtual environment is /Users/gitanjali/Desktop/plot_bridges2/venvtest.
I've installed a number of packages in venvtest through Terminal using pip. I'd like to be able to import three in particular -- basemap, matplotlib, and numpy -- to some code that I'm writing.
When I set the PyCharm project interpreter to be venvtest, those packages don't show up.
I've tried the following things to fix this problem.
I've made sure that the path to the venv is set correctly (/Users/gitanjali/Desktop/plot_bridges2/venvtest/bin/python).
I've called pip freeze --local from within the PyCharm project, and I get a list of all the packages I expect, since I installed them.
(venvtest) (base) DN0a229530:plot_bridges2 gitanjali$ pip freeze -- local
asn1crypto==0.24.0
backports-abc==0.5
backports.functools-lru-cache==1.5
basemap==1.2.0
...
six==1.12.0
tornado==6.0.2
urllib3==1.24.3
However, when I look at the Project Interpreter window in PyCharm, none of these packages show up.
I've tried recreating the venv and invalidating caches and restarting PyCharm, but none of these have solved the problem.
What next steps should I try to get PyCharm to recognize the packages that exist in venvtest?
Try installing those by "file =>setting=> project interpreter=>addsign on upright => type in the package u want to install on top => click install package on bottom=>wait for the installation =>try it out!"
if still can't work, try pycharm help
I'm working on a web app and I use Django as framework.
I'm using VS Code on a macOS.
I get an error when I try to import some Django module. This is a screenshot of my code in error.
The error message is the following:
[pylint] E0401:Unable to import 'django.conf.urls'
I too was facing this error while working with Python virtual environments. In my case, it was happening because I have installed Django on my virtual environment and my base environment didn't contain any module named Django.
Base(Global) environment
and when I use the same command inside my virtual environment (myDjangoEnv)
Fix:
Now what I understood is that pylint uses the python interpreter to analyze our code and mark the error while we write the code.
Since I have three python environments in my system, hence three different python interpreters are available to my VS Code.
So if VS code uses the Python interpreter from the base environment, it will not recognize the Django module (import Error). Therefore, you are required to change the Python interpreter to the one present in your virtual environment.
It sounds complicated but it is pretty simple:
Click on the bottom left of the screen to change python interpreter.
Select from the list of available Python interpreters. Make sure you select the appropriate interpreter with respect to the current project.
Follow steps mentioned in the image. For details, or if that doesn't work, read further!!!
If you can't see your interpreter (installed in the virtual environment) listed in the drop-down list OR selecting interpreters listed don't rectify the error.
Then, you have to give the path of your interpreter (installed in venv) to vs code. Because you might have installed Django only in your venv. Happens when you don't use anaconda to create venv.
Steps to rectify-
To check the path, activate venv and type which python in terminal, this will give path. Copy the path.
Click interpreter on lower left, to pull drop-down, as shown in pic above.
Click enter the interpreter path.
Paste path copied.
This will assign the right interpreter and rectify the error.
Locate your project's virtual environment. In my case, I am working on a Django project and my virtual environment is located on the path below:
C:/Users/abc/Desktop/Virutal36/myLab/Scripts/python.exe
Copy the address of your virtual environment.
On VS Code, Select File > Preferences> Settings to open your User Settings (or use the Ctrl+, shortcut).
Create or modify an entry for python.pythonPath with the full path to your virtual environment and you will be good to go. In my case it is:
C:/Users/abc/Desktop/Virutal36/myLab01/Scripts/python.exe
https://code.visualstudio.com/docs/python/environments#_manually-specify-an-interpreter
Ctrl+Shift+P
Type Python:select interpreter
Now we will get:
Choose Enter interpreter path:
Select Find...
Then
Check correct django version is properly installed and active?
In the active environment, calling this code in python interpreter shouldn't have errors.
from django.conf.urls import url
Check the VS studio python environment
https://code.visualstudio.com/docs/python/environments
You need to select the right environment. So, go to view in tool bar, then select command pallet(ctrl+shift+p), then type "python:select interpreter", then select the right virtual environment where you start you project.
In my case I solved it using the Select Interpreter option from VS Code's Command Palette (Shift + Command + P).
I chose the Python interpreter option which corresponds with the folder in which my virtual environment was and it solved the issue immediately.
Hope it helps :)
Are you using a virtual environment (mkvirtualenv)? In that case you need to make sure you install django and pylint etc., within your virtual environment too, using the following commands.
workon [yourEnvName]
pip install pylint
pip install django
pip install djangorestframework
and so on...for all the modules you want to use.
enter image description here
Choosing a global environment helped me to recover this issue
First check the requirements that you install djangorestframework, second if you work on virtual envs maybe the pylint that you use not check in your virtual env so you can install in local the package.
For me, I opened the nested folder of my Django project. So, Django couldn't find the modules of venv.
Just mentioning, I thought it might be helpful to someone.
