How to "re-install" a gem?

Question is pretty simple so instead of writting two commands is there one substitute? e.g.

gem uninstall subexec

gem install subexec

Is there just re-install, or something similar?

gem update <gem-name>

would update to latest available version. or

gem update

would update all gems to latest versions.

If you use bundler for gem installations then all you need to do is edit the gemfile and then run bundle install.

Depending on what you're trying to achieve, the following restores the gem to the contents of the .gem file:

gem pristine <gem name here>

You can also run that with --all if you want to clean your entire set of installed gems.

Nope, you have to do an uninstall and install.

No, there's no such command. You can, however, fit them on one line, if that's what you seek.

gem uninstall subexec && gem install subexec
