Is there a way to create the associated .ruby-version and .ruby-gemset files when creating a new gemset?

With older versions of rvm, one could do rvm --create --rvmrc 1.8.7@project, but that creates .rvmrc files.

I thought I read somewhere we could use the --ruby-version command line switch, but I have been unsuccessful in doing so.

I recently had the same problem. rvm --help led me to:

rvm --create --ruby-version ruby-1.9.3@my-gemset

It created both .ruby-gemset and .ruby-version.

  • And what if you already created the gemset? Will you be forced to add .ruby-version and .ruby-gemset manually at that point? – Donato Apr 02 '15 at 02:15
  • @Donato no, this will simply create the files, and move aside any existing .ruby-version or .ruby-gemset file into .ruby-gemset.Todays.Date.Time. In your project, type `ls -a` to verify the hidden files are there and as you expect. – Danny Oct 16 '15 at 16:35

    `rvm --create --ruby-version use ruby-x.x.x@project` – Asarluhi Feb 27 '16 at 17:55

According to the official RVM docs you can use this:

echo 1.9.3 > .ruby-version

Or you can use this:

rvm --ruby-version use 1.9.3@my_app

The second form will create both .ruby-version and .ruby-gemset.

  • if you want to only specify a ruby version and do it with `rvm` you would do: `rvm --ruby-version use 1.9.3`. This only creates a `.ruby-version` file. – bantic Dec 11 '14 at 17:00

Suppose I am creating gemset for my rails app whose name is tptapp then we can do it in following way.

rvm use 2.2.2@tptapp --create

here tptapp is name of gemset, 2.2.2 is Ruby version.

All of the above examples require you to type in your ruby version and gemset name .. which is close to the same keystrokes required to vi .ruby-gemset and vi .ruby-version. Assuming you are in a directory where you've already chosen your ruby version and you are pointing at the desired gemset.. this does the trick.

rvm --ruby-version use $(rvm-prompt)
