Is there a way via CLI to determine which version number of a gem is installed on my machine? Similar to yolk -l for python?
I'm trying to see if I have the latest version of compass / sass / zurb foundation. I have a dependency that requires a particular version number. So I need to see what version it is.
gem list
should give you a list of all your gems with version number in brackets behind it
StackOverflow has the answer and it might be a more useful place (for you) for Ruby architecture questions (they're still welcome here)
gem outdated
Not being a Ruby dev or having any gems installed, I'm not sure this is going to give you exactly what you're after but it should show you which ones need attention.
Otherwise I would have suggested gem query <package> (searches local) and gem query --remote to see available versions. If you only need local gem versions, the first aught to do.
If your gem's name is compass, then you could run:
gem list | grep compass
It will give you a list of gems, containing the phrase compass, and corresponding versions.
You can do it like this:
bundle info { gem name }
Or look in Gemfile.lock:
grep { gem name } Gemfile.lock
To add to @Belogron’s answer you can use
gem list MyGem
To list the installed versions of MyGem
You can then type
gem which MyGem
To display the specific version that is being used.
gem -v
It works for me. Checked in deepin 15.9.1(debian distro)
