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.

My issue requires some backstory.
I was having some troubles with pip, so I reinstalled Python. After the reinstall pip began to work, but Pycharm, my IDE, could no longer find Python. When I reinstalled Python it created a new folder for itself (Python310), but Pycharm kept looking in the old folder (Python39). I couldn't figure out how to get Pycharm to look in the new folder. Even deleting and reinstalling it did nothing.
So, I renamed Python310 to Python39 and changed the PATH. Now Pycharm can find Python. But pip has developed a new and exciting error. When I try to use it I get the following message:
Fatal error in launcher: Unable to create process using '"C:\Users\user\AppData\Local\Programs\Python\Python310\python.exe" "C:\Users\user\AppData\Local\Programs\Python\Python39\Scripts\pip.exe" install numpy': The system cannot find the file specified.
If I read this correctly pip is still trying to look in Python310. Would you please tell me what I need to do to get pip to looking in the right place?
So, to start. You don't fix this by renaming the folder where the interpreter resides. Even if that worked, it's not a fix. The name will say one thing, but it's actual version, compatible libraries, and anything else tied to the version number would be incorrect.
If you take a close look at the error message from pip, it tells us what's wrong.
Fatal error in launcher: Unable to create process using '"C:\Users\user\AppData\Local\Programs\Python\Python310\python.exe" "C:\Users\user\AppData\Local\Programs\Python\Python39\Scripts\pip.exe" install numpy': The system cannot find the file specified.
You renamed the directory, so your IDE can find it, but pip and everything else using the Python interpreter is still configured to look in the Python39 directory to find it.
The problem you are having is that your IDE, PyCharm, needs to be configured for your project. You have to tell it where the Python interpreter is. The simple solution, you can rename your your Python folder back to it's original state, and add it to your project.
Press Ctrl+Alt+S to open the project Settings/Preferences and go to Project | Python Interpreter. Click the Add Interpreter link next to the list of the available interpreters.
Expand the list of the available interpreters and click the Show All link.
Select the target interpreter.
In your case, look for the one with this file path: "C:\Users\user\AppData\Local\Programs\Python\Python310\python.exe"
I would recommend going one step futher and create an interpreter in a virtual environment. Especially if you are interested in Python beyond a very casual hobby. They are unavoidable.
This link is a good source and can help you with this:
https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html#interpreter
There, you will find screenshots that follow the steps I listed above. There are also detailed instructions on how to create and add a new interpreter in a virtual environment. The relevant headings are as follows:

The rest of the content is great as well, and may help answer questions you didn't know you had.
try to uninstall all of the existing python versions. and install it again. using any of application allow you to delete most of files, so to prevent error when re-install .
Option 1:
delete and reinstall again. and then when creating a project it should prompt you to pick a basic interpreter, choose python310 or whatever version you're using.
Option 2:
use a different IDE.
I have a script that I need to run using a very specific python interpreter in my hard drive.
I am using vscode as the IDE and trying to select the python interpreter using the command palette.
However, since the concerned interpreter is not present, I manually search it.
However, even after that, it doesn't work as typing python in the terminal then opens the windows store for installing a python IDE. I also tried adding the interpreter's path to the environment variables but the problem still persists.
How do I solve this issue.
Thank You for the help.
The Python version you selected on VS Code only effects the editor. Right click to any file on the sidebar and select Open in Integrated Terminal. If your selected Python version is created with virtualenv it will activated and your python command works.
If not worked and you want a global Python version, you need to add Python path to your system variables to work python command. Check this:
https://geek-university.com/python/add-python-to-the-windows-path/
Btw I don't think your python.exe in FreeCad/bin directory is proper Python version
At the bottom left you can select the Python interpreter.
Here it shows you on -how to do that: Python Interpreter
Reason:
Your system environment path contains this: %USERPROFILE%\AppData\Local\Microsoft\WindowsApps.
Solution:
Open Window Search(Win) to find Manage app execution aliases. To turn off App Installer of python3 like this:

When I am writing
from flask import Flask
One Yellow line is coming up under flask and stating Import "flask" could not be resolved from source Pylance (reportMissingModuleSource) . Also, I am able to do the work with this package also successfully. But the thing is, I am not able to use autosuggesstions for Classes and methods very well.
Further:
I have checked that flask is installed successfully.
Also I visited this thread https://github.com/microsoft/pylance-release/issues/236
And I set up my settings.json in vscode as follows:
"python.analysis.extraPaths": [
"/media/sarimurrab/New Volume/COURSES/Flask/FlaskMigrateforDatabaseMigrations/2"
]
But Still, unable to resolve the error.
When I did not install the module "flask" in the Python environment currently used in VSCode:
Please use the command "pip --version" to check the source of the module installation tool "pip", the module is installed at this location:
Then, we can use the command "pip show flask" to check the installation location of the module "flask": (It checks whether the installation location of the module is consistent with the Python environment displayed in the lower left corner of VSCode.)
If the "reportMissingModuleSource" message is still displayed here, please reload VS Code.
(F1, Developer: Reload Window)
Are you using a Virtualenv? If so make sure that VSCode is using the virtualenv as your python interpreter, otherwise it will not be able to pick up the packages that you installed inside this virtualenv.
To do so, click on the Python interpreter in your bottom bar, you should get a list of possible python interpreters including your virtualenv.
I had a similar issue while trying to import flask on vscode.
I fixed it by using anaconda. Simply you install the flask module in your created environment example screenshot.
How to create a virtual env in anaconda:
1. On the left sidebar, click on environments.
2. Click create (at the bottom).
3. At the pop-up window, give your vir.env a name
and select the language version.
4. Once created, you can start installing
different modules in your environment.
I hope that helps!
For Linux Mint and for those who have installed flask, but VSCode doesn't find it:
check the Flask path: pip show flask (should be smth like
Location: /home/<username>/.local/lib/python3.8/site-packages
in VSCode click left bottom button and choose the python interpreter, in my case I changed it from python3.9 to python3.8 as we can see it in the flask path.
That's because you have not chosen your path correctly,
type:
pipenv --venv
then it will show you where your virtual env is installed. Check where the packages are installed in your env, and then type what comes to you from the shell\scripts or whatever\python, and the packages will work.
I solved my problem by using a "Global" version of Python. Maybe Pylance had not updated to work with the version of Python I was using.
interpreter language screenshot
I was facing same issue. I tried all solutions from stack-overflow but none worked. But after lot of searching and time waste I found my silly mistake. I had created folder named 'flask' and stored my project there. I'm beginner and going through lot of such silly mistakes. Hope it would help, if somebody commits same mistake.
I think this is a Vscode problem ,just restart the Vscode .
By the following steps, I solved this issue:
1)On the project directory create the .flaskenv file
In the .flaskenv file write the following two lines:
FLASK_ENV=development
FLASK_APP=main.py
Please pay attention that main.py is my main file after writing flask run in the Vscode terminal, additionally, you have to create an env folder or requirement file proviosly.
A few answers (Jill's, Marius's, and Roy's) mention the fact that is necessary to choose the correct Python interpreter to make Pylance function properly. I would like to add the fact that this is still necessary to do when using a Jupyter Notebook with the correct Python kernel already chosen.
It is counterintuitive to choose both Python interpreter and notebook's Python kernel to make things work. It is even more counterintuitive considering the fact that Python interpreter's button (on the left bottom of the screen, on status bar) does not necessarily appear when a Jupyter Notebook is open, but when a Python script is open. For instance, in this screenshot, we see the little line under Scikit-learn's import, indicating a problem with the import (even though the import is successful). However, the correct Python kernel, with Scikit-learn installed, is already chosen. Only opening a Python script we notice that the Python interpreter is the reason of this behavior, because a wrong one is chosen, without Scikit-learn. In some sense, one could think that the reason behind this was a problem with the Python kernel or the Conda environment (it is common to experience this kind of problem when experimenting with Jupyter Notebook and Jupyter Lab). I hope this answer may help those who are searching for solving this problem in the specific context of Jupyter Notebooks inside VS Code. They could ignore the other answers because they could think it is not the case for them.
I upgraded to Catalina today, which required updating BBEdit as well. Now I am having trouble using my virtual environment, specifically the debugger in BBEdit.
I installed python3 in a virtual environment via Homebrew, set the correct path, and can access the virtualenv correctly via:
cd /Users/joecat/venvjc
source /Users/joecat/venvjc/bin/activate
I used pip3 to install modules needed
I am trying to run this test script:
#!/Users/joecat/venvjc/bin/python3
import pandas
print('hi')
The pandas module is only in the virtual environment so it should work. If I "Run in Terminal" through BBEdit, the code executes:
But when I try to run in debugger via Command+D, the code executes without the "pdb" debugger popping up at all:
Then, if I adjust the first line to be a "fake" path (assuming this just skips it) it correctly opens up the debugger, and pandas can't be imported because it's no longer using the virtualenv, which is correct:
#!/Users/joecat/venvdddddjc/bin/python3
import pandas
print('hi')
What am I doing wrong with respect to changes to Catalina/BBEdit? I switched to using zsh over bash... is that part of the problem? I am a newbie and happy to provide more details if needed. Thanks for any help anyone can provide.
There have been a lot of changes over time to how BBEdit interacts with the shell environment. As of 13.0.4, BBEdit will run your login shell to capture its environment, whenever you run a #! script. But there are special cases for Python, Ruby, and Perl, since those all have built-in support in BBEdit.
One thing to be aware of: if you've switched to zsh from bash, a common practice is to copy your bash environment from .bash_profile to .zshrc. This won't work correctly in BBEdit, because the shell that BBEdit runs is not an interactive shell.
For that reason, you should set up the majority (and perhaps all) of your zsh environment by putting the declarations (PATH, etc) in either .zprofile or .zshenv (but not both). Any interactive stuff can remain in .zshrc.
(And if you're still stuck, writing to support#barebones.com is always a good idea.)
(p.s. I would not recommend using any BBEdit version older than 13.0.4 on Catalina.)
I was able to correct the issue by downgrading to BBEdit 12.1.16, the earliest release that works with Catalina, as opposed to the latest version 13.0.2 that I was using.
This may be a bug in BBEdit, or else there's something else that changed this functionality between 12 and 13.
Would love to learn more if anyone has any information on this issue. Google is turning up next to nothing on this problem
In case it is helpful to anyone who comes across this issue, I was able to resolve this by importing and setting trace on the pdb module in lines 2 and 3 (right after the virtual environment path set on line 1):
import pdb
pdb.set_trace()
This allows the debugger to run normally in BBEdit 14.1.2, macOS Monterey 12.3.1.
No idea what the underlying issue is. I guess pdb is naturally imported when using the native OS python, but must be manually imported when using a virtual environment.
Hope this helps.
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.
