Create .ruby-version and .ruby-gemset with rvm

Question

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

Answer 1

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.

Answer 2

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.

Answer 3

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)

Answer 4

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.
