Python setup.py install specify extras_require

Question

I have "extras_require" declared in setup.py. Is there a way I can specify optional features with something like python setup.py[extras] install.

I know that pip can handle optional features like:

pip install .[extras]

or

pip install -e .[extras]

Is there something like python setup.py install [extras] or python setup.py develop [extras] that can do the similar things. Or is there another way to tell python setup.py to install some optional requirements.

Answer 1

python setup.py install easy_install pkg_name[extras]

or

python setup.py develop easy_install pkg_name[extras]

This of course requires pkg_name to already exist in the search paths. It shouldn't install pkg_name a second time since the install/develop option would've already installed it. However the extras will be processed.

The advantage of this over pip install (options) .[extras] is that you can pass specific options to build/install/develop.
