How to install multiple ruby gems at once?

Question

Is is possible to install more than one gem at the same time with only one command?

Answer 1

You can put them in a Gemfile and use bundler (bundle install).

Alternatively, you could list the commands in a file:

gem install pg
gem install sqlite3

and use something like cat | xargs sudo to execute them.

**Consider using RVM to manage your gems into gemsets rather than installing them globally with sudo.
