How to fix “Your Ruby version is 2.3.0, but your Gemfile specified 2.2.5” while server starting

Question

I am getting this error while running server, how do I fix this?

Answer 1

A problem I had on my Mac using rbenv was that when I first set it up, it loaded a bunch of ruby executables in /usr/local/bin - these executables loaded the system ruby, rather than the current version.

If you run

which bundle

And it shows /usr/local/bin/bundle you may have this issue.

Search through /usr/local/bin and delete any files that start with #!/user/bin ruby

Then run

rbenv rehash
