:bulb: This post covers how to fix the process path error that prevents Python or pip commands from running.

[01] Situation

  • Environment: Windows 10, VSCode, Git
  • Set up a Python venv on Machine A
  • Uploaded the result to a GitHub repository
  • Downloaded (git clone) the repository on Machine B to continue work
  • Entered the virtual environment (.\venv\Scripts\activate) and ran python/pip commands, triggering the following error:
    • Fatal error in launcher: Unable to create process using “path1” “path2”

python-interpretor error

[02] Cause

The Python/pip paths baked into the virtual environment differ between machines (e.g., E:... on Machine A vs. D:... on Machine B).

[03] Solution

:warning: The methods below are workarounds. If the runtime environment changes, you have to reinstall every time. You should look into whether only the venv environment variables can be updated.

3-1. Upgrade the virtual environment

# Before entering the virtual environment
