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

I had this problem but I solved it by installing the version of the ruby that is specified in my gem file using the RVM

    rvm install (ruby version)

After the installation, I use the following command to use the the version that you installed.

    rvm --default use (ruby version)

You have to install bundler by using the following command in order to use the latest version

    gem install bundler 

After the above steps, you can now run following command to install the gems specified on the gemfile

    bundle install
