RailsInstaller: Can I maintain the gem fold when re-installing a new version?

This is on Windows.

I just upgrade from Ruby 1.9.3 to Ruby 2.1.0 using RailsInstaller( and with other component like git, devkit, etc..). I doing this by uninstall the previous version, and then install a newer one.

The problem is that after uninstall , there is a Ruby1.9.3 left, with gem previouslly installed.

Now, since I upgrade to Ruby2.1.0, can I re-use this fold's gems? If so, How? Or I just delete that folder and re-install every gem again?

Solution

  • Gems are specific to ruby version.

    You should just delete the ruby1.9.3 related folder, and re-install all the gems for ruby 2.1.0 version by running bundle install.

    No harm in leaving behind the ruby 1.9.3 gems as well, but a good practice to remove them.
