How to use setup.py to install dependencies only?

问题

I am not interested in installing my package itself but I am interested installing all the dependencies used by my package. Is there a way to do this using setup.py? It seems setup.py installs my package and all dependencies.

回答1:

Use the -e flag on pip install

pip install -e .

回答2:

The only way I've found to reliably do this in a straightforward manner is this:

pip install . && pip uninstall `python setup.py --name`
