Your Ruby version is 2.2.4, but your Gemfile specified 2.3.1

Question

How can I update my ruby version to from 2.2.4 to 2.3.1 I am new to Ruby, I am using windows 8 and I do not have any ruby version manager install.

I can not change the ruby version on the gem file because I have to use the ruby version everybody else is using. So changin the ruby version on the gem file is not a solution

I can not use a ruby version manager.

Answer 1

Use RubyInstaller to install version 2.3.1.
