How to use the same Python virtualenv on both Windows and Linux

Short answer, NO. But you can share the venv build scripts.

1. pip freeze all libraries to a requirements.txt file.

   pip freeze > requirements.txt
   

2. Create the venv on each OS:

   python -m venv env
   source env/bin/activate
   pip install -r requirements.txt  # Install all the libs.
   

There are several reasons why venvs cannot be shared across OSes:

1. Some packages contains C extensions, and the OS’ .dlls are not compatible with each other.
2. venvs contain scripts with hardcoded paths. Windows and Linux paths are different.
