Why do I get the error “Your Ruby version is 2.0.0, but your Gemfile specified 2.2.2” although I have 2.2.2 installed

Question

I\'m using rbenv and I get the error Your Ruby version is 2.0.0, but your Gemfile specified 2.2.2 when I run the bundle install command in my project.

Answer 1

For me the problem was that I hadn't properly re-initialized rbenv after installing and switching to the new ruby version.

In my shell config I had an incorrect check to avoid executing source (rbenv init -|psub) if rbenv wasn't installed. After manually sourcing it worked again.
