How to fix rbenv: version `x.x.x` is not installed

Raw

fix_rbenv.md

So, you just cloned an existing project's repo and you run bundle install but you got the error: rbenv: version x.x.x is not installed....

What the issue means? The project uses a specific ruby version that you do not have on your system.

Here's how to fix it:

Install the Ruby build for the specified version using:

rbenv install x.x.x

If the above command doesn't run successfully and you get ruby-build: definition not found: x.x.x, upgrade brew and ruby-build using:

brew update && brew upgrade ruby-build

And run the rbenv install x.x.x command again.

Now, you have a new Ruby version, so you have to reinstall the gems you need (e.g. bundler, rails, etc). To be able to run bundle install again, run gem install bundler, gem install rails, etc to install the gems (bundler and rails) version for the newly installed ruby build
