RVM: Can set the default ruby version but cannot set the current version

Question

Problem: Though the default ruby is set to ruby 2.2.2. When I open a terminal ruby 2.2.1 is loaded. How do I ensure that ruby 2.2.2 loads when I open a new terminal.

Problem phrased differently: I am not able to set current && default to ruby 2.2.2 unless I uninstall ruby 2.2.1. This is what I get when I type rvm list

   ~ $ rvm list

    rvm rubies

       ruby-1.8.7-head [ x86_64 ]
       ruby-1.8.7-p374 [ x86_64 ]
       ruby-1.9.3-p551 [ x86_64 ]
       ruby-2.0.0-p353 [ x86_64 ]
       ruby-2.2.0 [ x86_64 ]
    => ruby-2.2.1 [ x86_64 ]
     * ruby-2.2.2 [ x86_64 ]
       ruby-2.2.4 [ x86_64 ]

    # => - current
    # =* - current && default
    #  * - default

I want the current && default to be ruby-2.2.2. If I type rvm use default I get the result as the following (which is what I want).

~ $ rvm list

rvm rubies

   ruby-1.8.7-head [ x86_64 ]
   ruby-1.8.7-p374 [ x86_64 ]
   ruby-1.9.3-p551 [ x86_64 ]
   ruby-2.0.0-p353 [ x86_64 ]
   ruby-2.2.0 [ x86_64 ]
   ruby-2.2.1 [ x86_64 ]
=* ruby-2.2.2 [ x86_64 ]
   ruby-2.2.4 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

How can I make sure whenever I open a terminal the environment current && default is set to ruby 2.2.2 as shown above? An observation: If I uninstall ruby 2.2.1 it defaults to the above situation. I have some projects which need ruby 2.2.1 and I cannot do that.

What should I do about this?

By the way which ruby gives the following output:

~ $ which ruby
/home/rk/.rvm/rubies/ruby-2.2.1/bin/ruby

Here is a similar question which has been unanswered: RVM default is 2.1.1 but 2.1.2 is loaded initially

Here is the out put of rvm info :

Answer 1

For me following command doing the work

rvm --default use 2.2.2

You might have issue with login shell and required to use /bin/bash --login as the command

Answer 2

我通过将 Rails 应用程序中的 .ruby-version 文件更新为您尝试使用的较新的 ruby​​ 版本（在您的情况下为 2.2.2）解决了同样的问题
