I feel like this is a super beginner question with an obvious answer but I'm missing it.
I'm installing a Rails project that includes a gem requiring me to use a version of Ruby that is 2.2.2 or earlier. Since my current system is set up with a newer version of Ruby, when I run bundle install, it fails because one of the gems can't be installed with the newest version of Ruby.
So, I set my system to use ruby 2.2.2 with rvm, rvm use ruby-2.2.2.
I then run bundle install and get zsh: command not found: bundle. Why is this? All my other commands work and I can install the problem gem individually with gem install.
What am I missing?
