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 would to create new Python project which include pipenv for manage my packages.
But when I try to install package with it, it throw me I exception :
ValueError: Not a valid python path:
'C:/dev/Anaconda3/Scripts/python.exe'
I try pipenv command with 2 differents emulation terminal (Cmder and Terminus) which produce same result.
In old time a try Anaconda solutions for work with Python. But now I don't want use this and I uninstall Anaconda in my OS.
It seems that my OS keep old reference to this python executable into Anaconda in your PATH... But I display my 2 PATH variables OS (PATH system OS and PATH user) and nothing has this location path into your string.
The directory c:\dev\Anaconda3 doesn't exist !
I try to search uninstall Anaconda program in my tool application manager Windows but Anaconda is not diplayed in that listing. It seems to be good uninstalled.
I install correctly pipenv executable : pipenv --version
pipenv, version 2020.6.2
I install correctly python executable : python --version
Python 3.8.3
I added 3 differents PATH python for my OS PATH (system PATH and user PATH) :
C:\dev\python\Python38
C:\dev\python\Python38\Scripts\
C:\dev\python\Python38\Scripts\bin
Why I keep old reference to Anaconda program ?
Why many program search python in same old deleted path and PATH variable do not included this ?
How pipenv created his PATH environment variable ?
I had a Python2.7 instance giving me the same problem. I copy/pasted its python.exe into the Scripts folder. So it now found a real python.exe there. Once I did this it continued on happily. And now I was able to use the Python3.9 version i wanted it to use anyways.
It seems like the python searcher should be a little more tolerant and just ignore poorly formed python releases. There is an open ticket for this: https://github.com/pypa/pipenv/issues/4334
I had a similar error because of an incorrectly uninstalled Anaconda. To see if you have the same problem, go to System Settings > Add or remove programs, and check for anything unexpected matching "conda". Trying to uninstall it results in an error because the uninstall.exe file cannot be found.
Searching around, I saw a few posts that said to mess with regedit, but that's scary. Instead, I re-installed the version of Anaconda that I needed to uninstall (you can do that with https://repo.anaconda.com/archive/Anaconda3-2020.02-Windows-x86_64.exe, replacing 2020.02 with your Anaconda version), and then uninstalling it via the proper uninstaller via "Add or remove programs". After a restart, the phantom Anaconda python was gone
You need to delete the old path in the Windows Registry.
Hit win + r
regedit
find folders with (Anaconda3 or Miniconda3).
Probably two folders. Do not delete folders with the new path to Python.
I am using Python 3.5.2 version on Windows 7 and tried using python3 app.py. I am getting this error message:
'python3' is not recognized as an internal or external command,
operable program or batch file.
Is there any specific cause about why the python3 command is not working?
I also verified that the PATH is added to environment variables.
There is no python3.exe file, that is why it fails.
Try:
py
instead.
py is just a launcher for python.exe. If you have more than one python versions installed on your machine (2.x, 3.x) you can specify what version of python to launch by
py -2 or
py -3
You can also try this:
Go to the path where Python is installed in your system. For me it was something like C:\Users\\Local Settings\Application Data\Programs\Python\Python37
In this folder, you'll find a python executable. Just create a duplicate and rename it to python3. Works every time.
Python3.exe is not defined in windows
Specify the path for required version of python when you need to used it by creating virtual environment for your project
Python 3
virtualenv --python=C:\PATH_TO_PYTHON\python.exe environment
Python2
virtualenv --python=C:\PATH_TO_PYTHON\python.exe environment
then activate the environment using
.\environment\Scripts\activate.ps1
Yes, I think for Windows users you need to change all the python3 calls to python to solve your original error. This change will run the Python version set in your current environment. If you need to keep this call as it is (aka python3) because you are working in cross-platform or for any other reason, then a work around is to create a soft link. To create it, go to the folder that contains the Python executable and create the link. For example, this worked in my case in Windows 10 using mklink:
cd C:\Python3
mklink python3.exe python.exe
Use a (soft) symbolic link in Linux:
cd /usr/bin/python3
ln -s python.exe python3.exe
In my case I have a git hook on commit, specified by admin. So it was not very convenient for me to change the script (with python3 calls).
And the simplest workaround was just to copy python.exe to python3.exe.
Now I could launch both python and python3.
If python2 is not installed on your computer, you can try with just python instead of python3
For Python 27
virtualenv -p C:\Python27\python.exe django_concurrent_env
For Pyton36
virtualenv -p C:\Python36\python.exe django_concurrent_env
Enter the command to start up the server in that directory:
py -3.7 -m http.server
I had a related issue after installing windows 11, where python3 in cmd would open the windows store. I was able to sort it out between this post and this other one. In short, I reinstalled python and made sure to add it to PATH. Then, in settings, Apps > Apps & Features > App Execution aliases. Here, all I had to do was make sure that every single python .exe (including idle and pip) were turned off EXCEPT FOR the python3.exe alias. Now it works like a charm.
FWIW:
The root of this issue is not with you or with python. Apparently, Microsoft wanted to make installing python easier for young kiddos getting interested in coding, so they automatically add an executable to PATH. For those of us that already have this executable, it can cause these issues.
Found out instead press the play button the top right and it should work in visual studios:
Do not disable according to first answer
Saying python3 in the command will not work by default.
After figuring out the problem with the modules (Solution): https://youtu.be/paRXeLurjE4
Summary:
To import python modules in case of problem to import modules:
Hover over python in search:

Im on win10 and have 3.7, 3.8 and 3.10 installed.
For me "python" launches version 3.10 and does not accept commands (like -3.7), "py" launches newest version but does accept commands, and "python3" does nothing.
Uninstalled 3.10 and "python" now does nothing, and "py" launches 3.8.
I am unable to add a comment, but the mlink option presented in this answer above https://stackoverflow.com/a/55229666/8441472 by #Stanislav preserves cross-platform shebangs at the top of scripts (#!/usr/bin/env python3) and launches the right python.
(Even if you install python from python.org, Windows will direct you to the app marketplace nowadays if you type python3 on the command line. If you type python on the same cli it will launch the python.org version repl. It leads to scripts that generate no output, but more likely silently failed completely. I don't know ho common this is but have experienced it on a couple of different devices)
If you have this at the top of your script to ensure you launch python3 and don't feel like editing everything you own, it is not a bad approach at all... lol.
I know how to start PyCharm in 32-bit mode on OSX Lion, but how do I get the interpreter configured in PyCharm to use the 32-bit version of the Apple shipped Python version (currently 2.7.1)?
I successfully have it working when launched from the terminal, but it appears that PyCharm doesn't read those system variables or defaults.
I'm trying to get cx_Oracle working with some scripts in PyCharm. Please see the following question for more details:
Can't get cx_Oracle to work with Python version 2.7 / mac os 10.7.2 (Lion) - missing_OCIAttrGet
Thanks in advance for your response!
I don't use PyCharm so I can't test this but it appears you can configure a non-standard path to the Python interpreter (see PYCharm help here). If so, try using /usr/bin/python as the path. If you've used the defaults command to permanently set 32-mode (as documented in Apple's man python):
defaults write com.apple.versioner.python Prefer-32-Bit -bool yes
that should do the trick. Setting the environment variable probably won't work.
UPDATE: Since you report that that does not work, here's another, more drastic possibility. You can extract the 32-bit architecture binary from the multi-architecture (universal) binary by using the lipo command. Try something like this:
sudo lipo /usr/bin/python2.7 -extract_family i386 -output /usr/local/bin/python2.7-32
sudo chmod 755 /usr/local/bin/python2.7-32
Then set the interpreter path in PyCharm to that file. It's ugly because you will need to keep an eye on any Python updates from Apple and repeat the process. If PyCharm is exec-ing the Python executable directly from the framework, then this may not work. Short of getting some support in PyCharm or resolving the Oracle issue, the fool-proof solution would be to install a 32-bit-only version of Python. The pre-built 32-bit-only installers from python.org are problematic for Lion 10.7 because of their dependence on gcc-4.0 and the 10.4u SDK, both no longer provided in Xcode 4. However, you could build it yourself or, with a little bit of configuring, you should be able to get MacPorts to build one.
For some reason none of that worked for me. Kind of lame that pycharm doesn't support this..
I ended up adding the BASH support plugin to PyCharm: Preferences > Plugins > Browse Repository > BashSupport
Then I add a new bash file to my project with the content:
#!/bin/bash
arch -i386 /usr/bin/python ./<your script name that's in the same directory here>
Run it by right clicking and running. Now it'll appear in your 'configurations' drop down.
Now you can run the script as 32-bit python, see the standard out, and edit the .py file.
How do I direct Eclipse to the Python interpreter on my Mac?
I've looked in Library which contains the directory 'Python' then '2.3' and '2.5', however they contain nothing except 'Site-packages' - Which is weird considering I can go into the terminal and type python. I then installed the latest 2.6 version with package manager and still can't find it. Can anyone help?
An alias to the python interpreter was likely installed into /usr/local/bin. So, to invoke python2.6, type /usr/local/bin/python2.6 or, most likely, just python2.6. If you want python to invoke python2.6, try rearranging your $PATH so that /usr/local/bin precedes /usr/bin.
Running $which python should help locate your Python installation.
I just solved this for my Mac and it was located in
/usr/bin/python2.7
The way I found it is as follows:
(1) I tried entering the following to see if I could find where Python was located
echo $PYTHONPATH
This had the location of a custom install of Python that came from another program I downloaded, but I wanted the native Python.
(2) I wanted to see every folder in the path so I could look for python
echo $PATH
This returned the following:
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/sbin
(2b) I CDed into every one of these locations and searched for python in each one.
cd /usr/bin/
ls | grep "python"
And I eventually found Python.
In Eclipse, with PyDev, if you (1) click Preferences (2) PyDev (3) Interpreter - Python, you can add the interpreter.
If you have installed python on mac, follow belows steps (on eclipse neon)
Click on Preferences
Search for python
Below screen will appear
Click Choose from list
It will show up all the python installed and select one for you
Hope it helps some one. It resolve my problem.
