Different pip install behavior depending on usage underscore/dot/dash in package name #5021
Description
- Pip version: 9.0.1
- Python version: 3.5.2
- Operating system: Ubuntu 16.04.3 LTS
Description:
Package name defined in setup.py is foo.bar. When running pip install --no-index --force-reinstall --use-wheel --upgrade foo.bar it works ok and package is uninstalled first. When running same command using package name foo_bar or foo-bar it seems to works but packages is not uninstalled first.
Why is it like that?
In my opinion upgrade behavior should be the same regardless of the used name of the package.
What I've run:

New python executable in /home/qba/.virtualenvs/foo/bin/python3
Not overwriting existing python script /home/qba/.virtualenvs/foo/bin/python (you must use /home/qba/.virtualenvs/foo/bin/python3)
