I'm using pip and virtualenv for my python application. I would like to upgrade to a new version of the application without touching the dependencies. When I use
pip install -U, it tries to upgrade all the packages, and even uninstalls and re-installs the same version of a dependency package when there isn't a new version available.
I also tried
pip install -U --no-deps but that seems equivalent to a regular install instead of an upgrade. Is there a combination of flags that will do what I want?
