The problem
I have a few projects in PyCharm, each with its own virtual environment.
Quite often, I add packages to these virtual environments using the CLI, mainly with python setup.py develop from another local package.
The new package appear in Preferences -> Project -> Project Interpreter and the calls to the newly-installed packages runs, but the imports still appear as erroneous, which drives me nuts:
What have I tried
Changing the virtual environment to a different one, than switching back, hoping it would reload. Did not work.
Restarting PyCharm. Works, but it's fairly slow, so I don't consider it a solution.
How do I refresh the virtual environment
For PyCharm 2018.3.4, I solved this by verifying that the correct source locations are specified under File/Settings/Project::Project Structure. All of the valid source directories should be marked as "Sources" and the venv directory should marked as Excluded, at least that's what worked for me.
I had similar issue mainly with local packages except I used pip install -e . and anaconda environment. This worked for me:
Use Ctrl + Shift + A shortcut
Type "Rescan Available Python Modules and Packages"
Instead of the first step you can use Help -> Find Action and then type "Rescan ...".
The only advantage of this solution is you don't have to restart PyCharm which is really annoying. But it does "Rescan", so does not help with speed much.
I have no enough reputation to comment on #Nerxis post. To complement his answer, I couldn't find "Rescan Available Python Modules and Packages" on Help > Find Action but it was on the Preferences search bar. You can define the key binding in Preferences > Keymap > Plugins > Python, in my case there was no key binding.

Error is: Import "brownie" could not be resolvedPylance
I know there are other SO posts that refer to this, but it seems most of them are talking about booting up a new env and installing x package into that virtual env.
However with Brownie, I'm especially confused because the brownie docs say:
pipx installs Brownie into a virtual environment and makes it available directly from the commandline. Once installed, you will never have to activate a virtual environment prior to using Brownie.
I don't want to mess with the virtual env that brownie uses.
Anyways, my code runs fine and the command line tells me that brownie is installed.It's just that this warning is really annoying me. Can anyone tell me how to clear it up? Thanks!
open command pallete cmd+shift+P (on mac)
type python select
click Python: Select Interpreter
Enter interpreter path
~/.local/pipx/venvs/eth-brownie/bin/python
this works for me.
It's happening because we install python with pipx instead of pip. pylance looks in the location our pip files are generally stored, and doesn't see brownie since we installed with pipx (which installed to it's on isolated virtual environment). So you have a few options:
Ignore it
Install brownie with pip in a virtual environment (not recommended)
If there is another suggestion, happy to hear it
for Windows:
Ctrl+Shift+P
Type python select
click Python: Select Interpreter
Enter interpreter path ~/.local/pipx/venvs/eth-brownie/Scripts/python
You can also click "Find" to search your files for the path if manually inputting it isn't working
This is an addition to #Ali Sıtkı Aslantaş's answer
I tried below pip command & the warning in my python code got resolved.
pip install brownie
The answer is probably quiet simple, as for me, each time I have to use different packages, I need to select the right interpreter in order not to get that silly warning.
If you are on Windows (I assume you are using VS code) follow the following steps:
View > Command Palette
Search for "Python: Select Interpreter"
Select "Enter interpreter path..." > "Find..."
Enter this path "C:\Users<< username >>.local\pipx\venvs\eth-brownie\Scripts" (of course swap << username >> with your username)
Select as interpreter the "python.exe" file contained inside of the Scripts folder.
Otherwise, if you are on an Apple device, the Steps to follow should be pretty much the same but at point 4) you need to enter a path that looks similar to the following: ~/.local/pipx/venvs/eth-brownie/bin/python.
So far, this method allowed me to solve any "Import" could not be resolved in Pylance.
The suggested methods seem correct, however, all of them are for Linux/OS, making the answer really confusing for the windows users.
I followed Patrick's tutorial and my path is: C:\Users\korisnik.local\pipx\venvs\eth-brownie\Scripts
^Korisnik Being the name of the account. It's honestly hard to find path if you don't know where to look at.
As the titles implies, VSCode is not updating the Interpreter to the correct one. Do mind that version 3.8.5 is not even present in my system anymore. Also the virtual environment is created with Python's venv instead of poetry.
The only thing that fixes the problem is a fresh installation of VSCode. I use a portable mode if that's something worth mentioning.
It's annoying to create a fresh installation and update my settings every time I happen to change between python versions.
If someone has an idea on how to fix the problem I'd would highly appreciate it. Thanks in advance
I have this problem because I have multiple .venvs in same workspace. My workaround is to
copy the full python path you want to point to
run cmd Select Python Interpreter
click Set At Workspace Level
click + Enter Interpreter Path.
Copy and paste the path.
Works for me.
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.
My project's running fine in virtualenv. Unfortunately, I can't yet run it via my IDE (Eric) because of the import troubles. It stands to reason, as I never told the IDE anything about virtualenv.
I know the drill ($ source project/bin/activate etc.), but lack general understanding. What constitutes "running inside virtualenv"? What IDE options might be relevant?
I think the only required setting to run or debug code is path to python interpreter.
Relevant IDE options could be SDK or Interpreter settings.
Note that you should run not default python (eg. /usr/bin/python) but python binary in your virtual environment (eg /path/to/virtualenv/bin/python)
Also there are some environment variables set by activate, but i think they aren't needed when you point to virtualenv python binary directly.
So, again, what activate does is only environment variables setup: at least, it modifies system $PATH in a way that python and pip commands points to executable files under path/to/virtaulenv/bin directiry.
As far as I know it is possible to run your script/project using your virtualenv simply by calling /path/to/your/venv/python your_script.py. To install new packages in your venv for example, you would run /path/to/your/venv/pip install some_package.
I guess the main advantage of "runnnig inside virtualenv" would be not being concerned about having to inform the location of python packages/executable everytime you want to run some script. But I lack general understanding too.
I usually install a virtualenv with the --no-site-packages option in order to have a "clean" installation of python.
--- EDIT ---
The second answer of this discussion has a nice explanation.
Simply look at the project/bin/activate, everything you need is there to set up the appropriate search.
Usually the most important path is the PYTHONPATH which should point to the site-packages.
Greetings to everyone!
I've got a little issue in a project made by someone in PyCharm, with virtual environment(VE) precisely. I've set this VE up few months ago and didn't use it for some time. Now i need to go back to it, because it has a lot of necessary things installed. Therefore there is one more battery needed to be installed into this VE - it is soundcloud API. I installed by directly from PyCharm in project settings, i checked whether this VE is still a default VE - it is. But project keeps complaining that there is "No module named soundcloud".
Can you show me the way i can fix this?
Thanks in advance.
In settings, under the Project section (in the left pane) go to Interpreters. From there you can select a found environment or click the + to add your own from a path. Find the environment you created and add it to the list. Then, once you select the environment you can see the installed modules underneath. You can add new modules through their built in pip.
After that, it'll take you to the first page where you have to select your custom environment from a drop down.
Good luck!
Edit: Reread your question. Sometimes when I can't get the module to be recognized in PyCharm, I do a pip install through the command line in the virtual environment. Then restart PyCharm.
Navigate to the environment in cmd and run python -m pip install -U SOUNDCLOUD_MODULE and it'll work.
