RubyGems

Like Pip, we can check which version of RubyGems we have installed with a simple gem command:

$ gem --version2.7.6

To list the installed gems, we can use list, funnily enough:

$ gem list*** LOCAL GEMS ***bigdecimal (default: 1.3.4)cmath (default: 1.0.0)csv (default: 1.0.0)date (default: 1.0.0)dbm (default: 1.0.0)did_you_mean (1.2.0)...

If we want to search for a package, we use gem search (we also have the --exact option in RubyGems, which Pip lacks):

$ gem search -e chef*** REMOTE GEMS ***chef (14.5.33 ruby universal-mingw32, 12.3.0 x86-mingw32)

We can also install (as a user) with gem install:

$ gem install chef --user-install

Note that by default, the .local gem installation location will not be in your PATH, but we can call it ...
