Visual Studio Code - ModuleNotFoundError, different sys.path in terminal and VSCode?

Question

I try running code in Visual Studio code but I keep getting a ModuleNotFoundError. When I run the code in my terminal or in debug mode in VS with the activated conda environment it works fine.

System: Mac M1 12.3

Conda Environment, selected in Visual Studio Code.

I have added this

import os
print('cwd is %s' %(os.getcwd()))
import sys
print('executable is %s' %(sys.executable))
print('path is %s' %(sys.path))

and running in terminal gives:

cwd is /Users/USERNAME/xyz/CodeFolder
executable is /Users/USERNAME/miniforge3/envs/conda_envNAME/bin/python
path is ['/Users/USERNAME/xyz/CodeFolder', '/Users/USERNAME/miniforge3/envs/conda_envNAME/lib/python38.zip', '/Users/USERNAME/miniforge3/envs/conda_envNAME/lib/python3.8', '/Users/USERNAME/miniforge3/envs/conda_envNAME/lib/python3.8/lib-dynload', '/Users/USERNAME/miniforge3/envs/conda_envNAME/lib/python3.8/site-packages']

running in VS via Run Python File (upper right corner button) gives:

cwd is /Users/USERNAME/xyz/CodeFolder
executable is /Users/USERNAME/miniforge3/bin/python
path is ['/Users/USERNAME/xyz/CodeFolder', '/Users/USERNAME/miniforge3/lib/python39.zip', '/Users/USERNAME/miniforge3/lib/python3.9', '/Users/USERNAME/miniforge3/lib/python3.9/lib-dynload', '/Users/USERNAME/miniforge3/lib/python3.9/site-packages']

running in VS via Debug Python File (upper right corner button) gives:

cwd is /Users/USERNAME/xyz/CodeFolder
executable is /Users/USERNAME/miniforge3/envs/conda_envNAME/bin/python
path is ['/Users/USERNAME/xyz/CodeFolder', '/Users/USERNAME/miniforge3/envs/conda_envNAME/lib/python38.zip', '/Users/USERNAME/miniforge3/envs/conda_envNAME/lib/python3.8', '/Users/USERNAME/miniforge3/envs/conda_envNAME/lib/python3.8/lib-dynload', '/Users/USERNAME/miniforge3/envs/conda_envNAME/lib/python3.8/site-packages']

I am confused - How can I get this running in VS Code?

---- Update March 23 2022:

I have three options

When I add

    "code-runner.executorMap": {

        "python": "$pythonPath -u $fullFileName"
        
    }

to

settings.json

(see [https://www.wiseowl.co.uk/blog/s2930/module-not-found-error.htm] 2 from @Kyouya Sato)

and run Run Code it works and I also get

cwd is /Users/USERNAME/xyz/CodeFolder
executable is /Users/USERNAME/miniforge3/envs/conda_envNAME/bin/python
path is ['/Users/USERNAME/xyz/CodeFolder', '/Users/USERNAME/miniforge3/envs/conda_envNAME/lib/python38.zip', '/Users/USERNAME/miniforge3/envs/conda_envNAME/lib/python3.8', '/Users/USERNAME/miniforge3/envs/conda_envNAME/lib/python3.8/lib-dynload', '/Users/USERNAME/miniforge3/envs/conda_envNAME/lib/python3.8/site-packages']

without changing

settings.json

it does also not work using Run Code.

Run Python File is not working at all.

Workaround:

1. Set "python.terminal.activateEnvironment" to false in the settings.json.
2. Downgrade to the previous version of the extension which works fine(avoid conda run).
3. Try out the following VSIX which has the potential fix: https://github.com/microsoft/vscode-python/suites/5578467772/artifacts/180581906, Use Extension: Install from VSIX command to install the VSIX.

Reason:

Conda has some problems:

1. conda run -n MY-ENV python FILE.py uses the base interpreter instead of environment interpreter.
2. Running using conda run inside already activated environment should be the same as running it outside
3. conda run does not remove base environment components from $PATH
