Introduction
Goal
My goal is to create a new app with the 5.2 Rails version.
Make sure you have Ruby installed
rbenv versions
ruby -v
Check the current installed Rails versions
gem list rails --local
Output
If you get nothing, it's because there's no Rails version associated with your current Ruby version.
List valid Rails versions
gem search '^rails$' --all
Output
Install the desired Rails version
gem install rails -v '5.2' -V --no-document
Output
Check the current installed Rails versions
gem list rails --local
Output
Double check the version
rails -v
Output
Rehash the directory
rbenv rehash
Output
Create the app
rails _5.2.0_ new myapp-backend --api
Output
Check the new app
cd app_name
Done
Celebrate
