How to fix “Your Ruby version is 2.3.0, but your G

Question

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

Answer 1

For $ Your Ruby version is 2.3.0, but your Gemfile specified 2.4.1. Changed 2.4.1 in Gemfile to 2.3.0

Answer 2

Add the following to your Gemfile

ruby '2.3.0'

Answer 3

Your Gemfile has a line reading

ruby '2.2.5'

Change it to

ruby '2.3.0'

Then run

bundle install

Answer 4

You better install Ruby 2.2.5 for compatibility

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

Answer 5

I am on Mac OS Sierra. I had to update /etc/paths and add /Users/my.username/.rbenv/shims to the top of the list.

Answer 6

If you are using rbenv then make sure that you run the "rbenv rehash" command after you set local or global ruby version. It solved the issue for me.

rbenv rehash
