Other Information:

• OS: Windows10
• Python Version 3.7.2
• VSCode Version 1.53.2
• ARPEL Version v2.0.1

Additional context

• python.pythonPath is set to "C:\Users\\.virtualenvs\Test_Project-Sy3-GYB1\Scripts\python.exe"
• I also tried setting AREPL.pythonPath to the same path, did not change anything
• When python for ARPEL is set to system python it works. However, modules can not be found as they are only in pipenv

[Almenon]

Thanks for reporting the issue, what version of python are you using for pipenv? You can find out the version with python --version

[Almenon]

Ooops you specified tha already, nevermind. Python 3.7 should work...

[Almenon]

I wasn't able to reproduce this on windows 10 w/ python version 3.7.1, pipenv version 2020.11.15, arepl 2.0.1 (same version), and vscode 1.53.2 (same version)

[Almenon]

it looks like you have a extra slash in your path, maybe try removing that?

C:\Users\\.virtualenvs\Test_Project-Sy3-GYB1\Scripts\python.exe
         ^

[freyn42]

Thanks for your reply.

I actually have double backslashes everywhere ("C:\\Users\\<username>\\.virtualenvs\\Test_Project-Sy3-GYB1\\Scripts\\python.exe"). They are seen as escape character otherwise. They were removed when copying except for the one followed by the dot... ah no, there should have been "<username>" in between there which I forgot.

Edit:
Ok. I did not forget anything... it's seen as formatting here... here we go.

So, I did the following:

• Installed python 3.7.9 over the 3.7.2 one.
  -> python --version within the venv in vscode showd 3.7.9 without changing anything in the venv-
  -> error still occurred
• Install python 3.8.7
  -> had to update Pipfile to 3.8 and recreate venv for 3.8.7
  -> everything worked fine
• Changed Pipfile back to 3.7 and recreated venv for 3.7.9
  -> everything worked fine
• Removed python 3.7.9 and reinstalled 3.7.2
  -> recreate venv for 3.7.2
  -> same error as before

To me it seems there is an issue with python 3.7.2.

[Almenon]

I tried 3.7.2 and it works for me. Can you try 3.7.2 without the venv?

[freyn42]

Yes. Without pipenv it works fine.
I mentioned that on my first post, but did not formulate this clearly 😏 .
