Creating gemsets

Gemsets must be created before being used. To create a new gemset for the current ruby, do this:

$ rvm 2.1.1
$ rvm gemset create teddy
Gemset 'teddy' created.

You can also create multiple gemsets in a single command.

$ rvm 2.1.1
$ rvm gemset create teddy rosie
Gemset 'teddy' created.
Gemset 'rosie' created.

Alternatively, if you prefer the shorthand syntax offered by rvm use, employ the --create option like so:

rvm use 2.1.1@teddy --create

If you would like to create gemsets automatically when used, export this flag in your ~/.rvmrc or /etc/rvmrc file:

rvm_gemset_create_on_use_flag=1
