Python setup.py develop vs install
Two options in setup.py
install are confusing me. According to this site, using
develop creates a special link to site-packages directory.
People have suggested that I use
python setup.py install for a fresh installation and
python setup.py develop after any changes have been made to the setup file.
Can anyone shed some light on the usage of these commands?
python setup.py install is used to install (typically third party) packages that you're not going to develop/modify/debug yourself.
For your own stuff, you want to first install your package and then be able to frequently edit the code without having to re-install the package every time — and that is exactly what
python setup.py develop does: it installs the package (typically just a source folder) in a way that allows you to conveniently edit your code after it’s installed to the (virtual) environment, and have the changes take effect immediately.
Note that it is highly recommended to use
pip install . (install) and
pip install -e . (developer install) to install packages, as invoking setup.py directly will do the wrong things for many dependencies like pulling prereleases and incompatible packages versions and make the package hard to uninstall with pip.
