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

问题:

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

回答1:

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

回答2:

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

回答3:

Your Gemfile has a line reading

ruby '2.2.5'

Change it to

ruby '2.3.0'

Then run

bundle install

回答4:

If you have already installed 2.2.5 and set as current ruby version, but still showing the same error even if the Ruby version 2.3.0 is not even installed, then just install the bundler.

gem install bundler

and then:

bundle install

回答5:

Add the following to your Gemfile

ruby '2.3.0'

回答6:

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.

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
