Can I force pip to reinstall the current version

Question

I ve come across situations where a current version of a package seems not to be working and requires reinstallation  But pip install -U won t touch a package that is already up-to-date  I see how to force a reinstallation by first uninstalling  with pip uninstall  and then installing  but is there a way to simply force an  update  to a nominally current version in a single step

pip install --upgrade --force-reinstall  lt package gt    When upgrading  reinstall all packages even if they are already up-to-date   pip install -I  lt package gt  pip install --ignore-installed  lt package gt    Ignore the installed packages  reinstalling instead

You might want to have all three options  --upgrade and --force-reinstall ensures reinstallation  while --no-deps avoids reinstalling dependencies     sudo pip install --upgrade --no-deps --force-reinstall  lt packagename gt    Otherwise you might run into the problem that pip starts to recompile Numpy or other large packages

If you want to reinstall packages specified in a requirements txt file  without upgrading  so just reinstall the specific versions specified in the requirements txt file   pip install -r requirements txt --ignore-installed

If you have a text file with loads of packages you need to add the -r flag  pip install --upgrade --no-deps --force-reinstall -r requirements txt
