Specify extras_require with pip install -e

Question

How can one manage to install extras_requires with pip when installing from a git repository ?

I know that you can do pip install project[extra] when the project is on pypi.
And you have to do pip install -e git+https://github.com/user/project.git#egg=project for a git repo but I didn't manage to find how to link these two options together.

Answer 1

This should work, per example #6

For remote repos:

pip install -e git+https://github.com/user/project.git#egg=project[extra]

And this for local ones (thanks to @Kurt-Bourbaki):

pip install -e .[extra]

---

As per @Jurt-Bourbaki:

If you are using zsh you need to escape square brackets or use quotes:

pip install -e .\[extra\]
# or
pip install -e ".[extra]"

Answer 2

Important to notice: you should not have whitespaces around or within brackets. I.e. this will work: -e ".[extra1,extra2]" but this won't: -e ". [extra1, extra2]" - and even as a row in requirements.txt file, where it is not so obvious. The worst thing about it is that when you have whitespace, extras are just silently ignored.
