It turns a blind eye to .ruby-version

In a Rails directory I have a file .ruby-version:

1.9.3-p392

I have this version installed, even so the main version of Ruby I use is 2.1.2. But for that project I need 1.9.3

In Gemfile I also have this:

source "http://rubygems.org"

ruby "1.9.3"

But nonetheless when I go to this directory in the terminal, it says:

ruby-1.9.3-p392 is not installed.
To install do: 'rvm install ruby-1.9.3-p392'

But as I said:

$ rvm list


 ruby-1.9.3-p547 [ x86_64 ]
 ruby-2.1.1 [ x86_64 ]
=* ruby-2.1.2 [ x86_64 ]

P.S. I also have another warning but I figure it's not related to this issue:

$ rvm list
Warning! PATH is not properly set up, '/Users/alex/.rvm/gems/ruby-2.1.2/bin' is not at first place,
         usually this is caused by shell initialization files - check them for 'PATH=...' entries,
         it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
         to fix temporarily in this shell session run: 'rvm use ruby-2.1.2'.

rvm rubies

Solution

Your .ruby-version file requires 1.9.3-p392. But you have installed ruby-1.9.3-p547. That are different versions.

To solve this problem install ruby-1.9.3-p392 (what the error message tells you):

rvm install ruby-1.9.3-p392

Or change your .ruby-version file to ruby-1.9.3-p547 and use that version.
