[solved]Ruby require failed

blubbb · 2015-01-07 11:47:38

Since I the upgrade to ruby 2.2 I can't require any gems in my ruby scripts(gem is installed):

/usr/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- nokogiri (LoadError)

Uninstalling and reinstalling gem didn't work. To run my scripts I now need to downgrade ruby, whenever I want to use vim I need to upgrade again to 2.2, because it depends on ruby 2.2:

/usr/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- nokogiri (LoadError)

Any solution on this?

Ruby uses /usr/lib/ruby/gems/2.2.0/$VERSION for gems so every major update it requires gem reinstallation.

Uninstalling and reinstalling gem didn't work.

Hmmm, it should help. How do you install/reinstall gems? Make sure you have your gem sources in /usr/lib/ruby/gems/2.2.0/

Another option is to use binary rubygems repo that I maintain - Quarry. It supports ruby 2.2.

Consider it solved, I tried it again and it worked. Insanity here I come...

Is there a fast/easy way to do this for ALL gems at once?

Collect ruby packages installed via AUR:

pacman -Qqm | grep ^ruby-

and install them via makepkg or any of the AUR helpers. After that /usr/lib/ruby/gems/2.1.0/ should be empty.

Another thing to check is output of https://aur.archlinux.org/packages/lostfiles/ script that shows files that do not come from arch packages (i.e. were installed via gem directly).

Arch Linux
