Setting up a python venv in vscode (macos) - python

I've poured through the current answers on this and none have helped. I can't get vscode to detect the virtual env I've created. I'm currently in a state where:
I added the path of the '/my/absolute/path/bin/python3' to the vscode default interpreter path.
As a result the linter is detecting the packages
However when I try to get vscode to execute the script it throws the "ImportError", therefore not recognizing the packages i installed in the virtual env.
Addendum: if i run the script with $python3 myscript.py Everything works fine.
I guess I could just run everything in the command line but it seems like a shame. Anybody got leads on how to fix this?
Thanks already :)

Can't run any Python files on Ubuntu(WSL)

I have just started working on my new pc and just to get a feel for it I wanted first to start working on python files, so I started first by just wanting to run WSL on windows and it installed correctly but when I want to run any python using the run python file on the top right on VS code, this is what gets executed $ C:/Users/jaffe/AppData/Local/Microsoft/WindowsApps/python3.10.exe f:/Projects/hello.py
And this is the error: -bash: C:/Users/jaffe/AppData/Local/Microsoft/WindowsApps/python3.10.exe: No such file or directory
I have no idea what's causing it but when I run the file using 'Shift + Enter' which is: Python: Run Selection/Line in Python Terminal it seems to run the single line correctly but it gives me this error instead:
print("Hello, world")
-bash: syntax error near unexpected token `"Hello, world"'
but when I run it using python3 hello.py, it works perfectly fine?! I'm so lost as to why this is happening and how could I fix it.
Might be relevant: I'm using windows 10, installed python 3.10.2 from windows store, all of that is in VS code and the python code is one line: print("Hello, world") and I changed the permissions of Local/Microsoft/WindowsApps so it's now accessible by all users to view/read/edit/run, made sure that python3.10.exe exists(on the WindowsApps and it works perfectly) and reinstalled it many times, tired python3.9, and tried to install python from the website instead of the windows store and still the same, manually added python to PATH and tried .venv and didn't work. when I launch python3.10.exe outside vs code it seems to run perfectly, I have worked with python before and it used to work fine now I don't know what's wrong.
I have seen other questions of the same problem I'm having here but none of them solve the problem.
No such file or directory C:/Users/...
For wsl, the Windows filesystem is accessible, but it has a different path. It is mounted under the /mnt folder. So you would find your python .exe under /mnt/c/Users/jaffe/AppData/Local/Microsoft/WindowsApps/python3.10.exe. This said, the executable file is meant to work on Windows, and it doesn't really makes sense to use it on Linux when you could run python within your wsl distro.
python3 works perfectly fine
This is because most Linux distributions come with python3 pre-installed, so you can use it already. To see where it is located, you can run the command which python3, or python3 --version to check its version.
If you want to change version, you may consider download it from you package manager, apt.
I also suggest to install python3-pip if you don't have it already to get the pip package manager for python.
In my case when I ran into this.. I discovered pyenv. This allows you to download more than one version of python. You can then go into a specific directory, such as your python project and issue a python local 3.10.0 (for example). Here's a link on how to install it as well as poetry which is a virtual environment manager that is become very popular. You can also create an alias for python that works off of this. I add this command to my alias file and source it from my .bashrc. alias python='pyenv exec python3'

Python trouble after Mac update: "No such file or directory" [duplicate]

When I switch my PyCharm to use Python 3.4.3 and I am getting the error:
Invalid Python SDK
Also PyCharm does not automatically find the Python 3.4 interpreter for me, even though it is on the desired path /Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4. See the screenshot:
Despite this the interpreter does work. I am able to get correct output as expected, but code completion related to Python 3.4 is not working.
E.g. print("hello world!) still shows an error on the editor, but the console shows the correct output.
This also happened to me. I renamed a repository and then my virtual environment got stuck in the old path.
I grepped all configuration files and could not find any reference to the old one.
What finally solved the problem was to clear caches with the option File > Invalidate Caches / Restart...:
I had the same issue.
Try to comment/remove the PYTHONPATH variable in your ~/.bash_profile
#export PYTHONPATH=/usr/local/lib/python2.7/site-packages/
If it does not help it also may be useful to look in the idea.log for the errors:
/Users/username/Library/Logs/PyCharm40/idea.log
I had the following errors:
Your PYTHONPATH points to a site-packages dir for Python 2.x but you are running Python 3.x!
PYTHONPATH is currently: "/usr/local/lib/python2.7/site-packages/"
You should `unset PYTHONPATH` to fix this.
I go the same error message in Windows version of PyCharm after I re-installed Python (3.5) on a different location. The problem was that most of my existing virtual environments registered in PyCharm were still referencing the old installation of Python.
I resolved it by deleting these existing virtual environments and creating a new one. If deleting existing interpreters (in virtual environment) is not an option, you should be able to modify them instead in File | Settings | Project Interpreter
I got the same issue, when I updated Python (3.x) version via Home brew in MacOS.
Above answers didn't work for me. But with those, I realize that, it's an issue with linking the directories. I deleted ~/.virtualenvs folder and recreated all virtual envs.
$ ls -a ~/.virtualenvs
local-dev wdias-dev
$ rm -rf ~/.virtualenvs
$ which python3
/usr/local/bin/python3
$ mkvirtualenv local-dev --python=/usr/local/bin/python3
$ mkvirtualenv wdias-dev --python=/usr/local/bin/python3
Open the PyCharm again, and it works fine.
I couldn't get anything to work, so I cloned my conda env (see how), called it something else, and then set it in PyCharm to the new one.
For me, changing the paths in ~\venv\pyvenv.cfg made PyCharm recognize the new environment after bringing my projects to a new PC.
I had the same issue in Windows10. I was so frustrated, beacause everything seems looked OK. I've added PYTHONPATH, I've restarted Pycharm and deleted old virtualenv folders and created new... It did't work.
And at the end I have just opened Pycharm in an administrator mode and it works!
When creating a new project my interpreter was set to python 2.7 so I had to change that to python3 and everything works like a charm
I got the same problem with Pop OS 21.04 and Pycharm installed via Flatpack. So i remove it and installed via Snap and started working again.
I ended up having to install Python as an admin and make sure it installed to the C:\Program Files\Python310 folder. I think The option was to make sure it installed for all users. If I installed it under for user's appdata it wouldn't work.
Once I did that I was able to point pycharm to the C:\Program Files\Python310\ for the interpreter. Pretty annoying but finally got it working
I've solved it too. Uninstalled python 3.10, installed python 3.9. Changed the python interpreter to 3.9 through pycharm setting. Created a new virtual environment.

VS Code doesn't recognize Python Virtual Environment Packages - It shows red underlines

I installed python virtual env. I use vs code. I imported scrapy in my code and vs code doesn't recognize the module. Actually, it works well when I run it. scrapy crawl tester
Just, vs code shows red underlines that mean "Unable to import scrapy" So this is just vs code issue, not venv or scrapy package install issue.
This code works well and actuallay, scrapy is imported without any issue. This is just vs code issue. Thank you.
You might be able to solve your problem by using CTRL+Shift+P to add "Python: Select Interpreter" to your project.
If you created a virtual environment and activated it as well
type which python on macOS/Linux,
type where python on Windows,
inside the activated terminal session.
(env) userpc#pc:~$ which python
/home/userpc/Desktop/foldername/env/bin/python
In VSCode press Ctrl+Shift+P, under >Select Interpreter paste the location you receive using the former command.
Once done, restart VSCode.
VSCode will also ask you to install pylint in your environment and if it doesn't you can do the same by activating you environment and typing
pip install pylint
inside the activated terminal session.
Ran into the same problem - selected the correct Python interpreter in VS Code, pip installed all the desired Python libraries but import is still underlined in VS Code.
What you need to do
What worked for me is to make sure that the linter that you are using in this VS Code instance (I was using pylint) is from the bin folder of the virtual environment, not somewhere else.
How you can do it
I'll use the absolute path to the desired virtual environment /User/ProjectFolder/env as an example.
To check that you meet the conditions stated in What you need to do, toggle the settings.json file in VS Code by pressing ⌘ + ,:
Make sure that the correct Python interpreter is selected. i.e. "python.pythonPath":/User/ProjectFolder/env/bin/python3.
Make sure that the linter (e.g. pylint) is located in that bin folder, not anywhere else. i.e "python.linting.pylintPath":/User/ProjectFolder/env/bin/pylint, NOT something like "python.linting.pylintPath":/usr/local/bin/pylint.
This means that you have to install your desired linter in the virtual environment.
Hope this helps.
I tried #cleon-w's answer which worked for me. (Thanks Cleon)
I was using pyenv on my Mac M1 (Big Sur) with vscode. vscode could not resolve the
paths to python that the pyenv provides, so I looked within the pyenv scripts to find the absolute paths
to the underlying python and the pylint files.
As #Cleon W says I ensured pylint and python are in the same bin directory.
Then edit VS Code settings.json to point to them directly (bypass .pyenv) and the imports could be found.
settings.json (vscode)
"python.defaultInterpreterPath": "/Users/USERNAME/.pyenv/shims/python",
"python.pythonPath": "/Users/USERNAME/.pyenv/versions/3.9.1/bin/python",
I have similar problem with Django. What solved my problem was:
create .vscode/settings.json file inside root dir for project.
add this json {"python.defaultInterpreterPath": "path to bin directory in root dir for project"}
Ctrl-Shif-P -> Python: Select Interpreter -> select one that said: Use Python from python.defaultInterpreterPath. If it's not in the list, hit refresh (circled refresh button on the top of settings box).

PyCharm not recognizing my python interpreter and PIP packages. Maybe PATH issue?

So I have been having issues with getting PyCharm to find my python3 interpreter on my Mac. I have downloaded a few packages with pip from the terminal and when I use the python shell from the terminal and import them, I get no errors.
When I check where these packages are downloaded, I get this path:
/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.>7/lib/python3.7/site-packages
So the issue is when I try to use the PyCharm IDE I don't have access to these packages. I have gone into the settings to change the interpreter and I have tried all these options, none of which show my installed packages.
![1]:https://i.imgur.com/dhTg8CV.png
I have also tried navigating to that path where it shows my packages are downloaded and selecting the python.exe (the highlighted file) I find, but get this error with PyCharm ->
![2]:https://i.imgur.com/DbW5y6I.png
![3]:https://i.imgur.com/B8H4hlA.png
I have a feeling I am selecting the wrong python.exe but I don't know where to look. I also think the problem could stem from me installing iTerm and the zshrc bash program and it changed my paths, but I don't know why python would be working from my terminal then. Just in case, this is what my Path is in my zshrc file:
export PATH=$HOME/bin:/usr/local/bin:$PATH
export PATH="$HOME/.composer/vendor/bin:$PATH"
export PATH="/usr/local/bin:/usr/local/sbin:~/bin:$PATH"
Sorry for the long post and no inline images, this is my first post. Any help would be greatly appreciated! Just trying to get this to work so I can work on a project.
Update
just thought it would be useful to know that when i type "which python3" in the terminal it returns -> /usr/local/bin/python3
The simple solution is
Open the pycharm
Go to top left most side on IDE and open FILE dropdown.
Open the project which contains PIP files.
By this procedure pycharm automatic detect the virtual environment.

pip in venv on Windows 10: 'Fatal error in launcher: Unable to create process using '"c:\users\..." ' encountered during flask tutorial

I'm going through the Flask tutorial, and I encounter a problem where I can't use pip (and thus anything else really) a venv in Powershell. The same flask app runs correctly in an Ubuntu terminal with Python 3.6.6 in WSL.
The problem seems to depend on the directory, which makes me think it's somehow related to file path length; I enabled long file paths in the windows Group Editor but this hasn't fixed the problem. In the below steps my venv directory is c:\users\rwgpu\google-drive\code\flask-tutorial\winEnvflaskr\ and I experience the error, but everything works correctly in the directory C:\python\test\testVenv. (in each case I'm running the commands in the directory one up from the listed above, flask-tutorial and test respectively)
Minimal steps to reproduce are:
Completely fresh Python 3.7 installation.
Change directory to app folder.
py -m venv winEnvFlaskr
./winEnvFlaskr/Scripts/activate
pip list
The ultimate goal is to then
pip install FLask
and run the Flask tutorial app. Again, all steps work correctly in Bash on Ubuntu in WSL (running its own Python) and in a different windows directory with the same Python 3.7.
After pip list I get the error:
Fatal error in launcher: Unable to create process using '"c:\users\rwgpu\google-drive\code\flask-tutorial\winenvflaskr\scripts\python.exe" "C:\Users\rwgpu\Google-Drive\Code\flask-tutorial\winEnvFlaskr\Scripts\pip.exe" list'
and if I try
python -m pip list
I get nothing; the terminal hangs for a second and returns with no output. If I run
py -m pip install -U pip
in the bugged venv it will try to install and report success. It will do this again, and will never report "requirement already satisfied" which would be correct.
I had the same problem on Windows with running flask in command line from venv(for example, "(venv)...\flask run"). I resolved the problem with changing path in flask.exe code(open "your_venv\Scripts\flask.exe" with notepad or etc.): in my way I correct the 436-th line at the end; you need to put there "your_absolute_path_to_venv\Scripts\python.exe" instead of the path indicated there.
Good luck!
Well, I still don't know why this was happening -- it persisted through deleting and recreating the venv (obviously), but when I deleted the entire folder, that somehow cleared it up. I just copied the code into a new directory in the same parent and everything seems to be working ¯\_(ツ)_/¯
If anyone knows what would cause this in my case I still welcome input.
