Python: How to force overwriting of files when using setup.py install (distutil)

I am using distutil to install my python code using

python setup.py install

I run into problems when I want to install an older branch of my code over a new one: setup.py install won't overwrite older files. A work around is touching (touch <filename>) all files so they are forced to be newer than those installed, but this is pretty ugly.

What I am looking for is an option to force overwriting of all files, eg. something like

python setup.py --force install

Any Ideas?

Solution

  • The Python developers had the same idea, they just put the option after the command:

    python setup.py install --force

    The distutils documentation doesn't mention the --force option specifically, but you can find it by using the --help option:

    python setup.py --help install
