I get a traceback error when using the command "pipenv run python"

UPDATE: The issue comes from the special characters in the path where the .virtualenv directory is created. I fixed it by rerouting the .virtualenv in C: and will eventually edit the username to avoid this issue in the future.

I am having some trouble with "pipenv run" on my work laptop (windows pro) and can't seem to find an explanation to my issue. For example, I create a test directory on the desktop in which I put a basic scripts that prints "Hello".

I initiate pipenv in the project folder and it works fine, I can fire up the shell, install packages, run the script (While in the shell), etc..

However, I get a traceback whenever I try to run the script from the main command prompt as such (not inside of pipenv shell):

C:\Users\jérôme\Desktop\tester> pipenv run python testit.py

some other details:

  • running the above command on my personal machine (windows family edition) works fine
  • I did "pipenv lock" before to check if it could be the issue. It was not
  • I am using python 3.7.9 on both machine
  • Python was added to path variables on installation
  • I tried with python 3.8.6 as well and get the same error
  • I tried uninstalling completely all python versions and reinstalling it
  • the username on my work machine as special characters (é, ô) could it be the reason?

Solution

  • The root cause of the problem are the special characters in the user's directory path, where the pipenv's .virtualenv directory is also created by default. The OP reports to have fixed the problem by rerouting the .virtualenv in C: 

    A quick test in, e.g. c:\tmp can help to rule out this cause.
