update source code of locally installed pip package

I installed my package with pip install -e . If I now change something in the source code, do I need to run pip install -e . again or will it consider the updated source files when I run the program? Thanks for your help! Tamme

Solution

  • No, you don't need to reinstall the package. That's what the editable install (mentioned by the -e option) does; instead of installing the package to site, it only puts a link to the source files.

    However if you modify the package metadata (things like author's name, description, version etc. the stuff found in setup.cfg or setup.py) that wouldn't be carried over, for that change to reflect you need to reinstall the package.
