gem: Install the latest version of a gem.
$ gem install ${gemname}
try on your machine
The command "gem install ${gemname}" installs a Ruby gem (a packaged Ruby library or application) specified by ${gemname}.
Here's how the command works:
-
"gem" refers to the RubyGems package manager which allows you to easily manage Ruby libraries and applications.
-
"install" is a command that tells gem to install a specific gem.
-
"${gemname}" is a placeholder that represents the name of the gem to be installed. You need to replace this placeholder with the actual name of the gem you want to install.
For example, if you wanted to install the "rails" gem, you would use the following command: "gem install rails".
