Rails: I installed Ruby, now “bundle install” doesn’t work

January 21, 2022 by admin

Bundle with Ruby 2.1.6

You just need to install bundler :

rvm use ruby-2.1.6
gem install bundler

This will be installed in a gemset specific to ruby-2.1.6, so it won’t interfere with anything you installed with ruby-2.3.0. You can use

bundle install

to install the required gems.

Alternatively, you could just try the example you downloaded with ruby-2.3.0 by either changing the

ruby '2.1.6'

line or deleting it from the Gemfile.
