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

You better install Ruby 2.2.5 for compatibility. The Ruby version in your local machine is different from the one declared in Gemfile.

If you're using rvm:

rvm install 2.2.5
rvm use 2.2.5

else if you're using rbenv:

rbenv install 2.2.5
rbenv local 2.2.5

else if you can not change ruby version by rbenv, read here
