Install the same version of Ruby in 2 different folders with rbenv

I installed rbenv from one directory, now I am in another directory and I no longer have the same version of Ruby installed, which I understand is the point of rbenv to have the option of multiple versions of Ruby installed.

I installed rbenv to begin:

brew install rbenv

Now in the following folder ~/Users/steven/xyz/work/ I installed Ruby 2.3.1:

rbenv install 2.3.1

Then I was told to add it to my bash_profile using nano ~/.bash_profile:

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

Now when I use ruby -v in ~/Users/steven/xyz/work/ I get ruby 2.3.1p112 which is good.

However, when I jump over to ~/Users/steven/xyz/projects, ruby -v gives me ruby 2.0.0p648 which is not good.

So, how do I now get Ruby 2.3.1 in the other folder?

Solution

  • If you use rbenv you can create a ".ruby-version" file using:

    rbenv local 2.0.0-p353

    which is stored inside the .ruby-version file. Just replace 2.0.0-p353 with your version of Ruby.

    You can specify a Ruby version inside gem file if you use RVM:

    source "https://rubygems.org"
ruby "2.3.1"

    When you switch folders it will load the Ruby specified in the Gemfile. For other engines you can use:

    ruby "2.2.2", :engine => "jruby", :engine_version => "9.0.0.0"
