'Returned non zero exit status 101 giving an error when I tried create a Virtual environment

When I run py -3 -m venv venv on command prompt to create a virtual environment it fails.

"Error: Command '['C:\\Users\\Guest\\Desktop\\Python Web 
 App\\venv\\Scripts\\python.exe', '-Im', 'ensurepip', '--upgrade', '--default- 
 pip']' returned non-zero exit status 101. 

How to fix this? I've installed the latest Python Version. I'm stuck here on my way to set up Flask for web development.



Solution 1:[1]

This happened after I upgraded from python3.8 to python3.9.

sudo apt install python3.9-venv

should solve the issue

I had this problem - the workaround was to uninstall Python and reinstall it with the Install for all users option. See my longer answer: https://stackoverflow.com/a/62207756/11308690

I tried reinstalling python to no avail. This problem seems to occur when copying the python executable doesn't work (fully) for whatever reason. I recreated my venv with the --clear --symlinks:

python -m venv --clear --symlinks ./venv

I also faced the same problem after upgrading to python 3.9.2 "Error: Command '['C:\Users\Chicool Ph G\PycharmProjects\InvenoryTrackingSystem\venv\Scripts\python.exe', '-Im', 'ensurepip', '--upgrade', '--default- pip']' returned non-zero exit status 101"

It worked;

  1. unistall the Python 3.9.2
  2. reinstall the Python 3.9.2
  3. Select Custom install
  4. Check(Tick) install for all users
  5. Click install
