So Rails 2.6 has been released and I just went thru the normal update dance. Here's how I handled upgrading my system. Let's start with the basics:

  • rvm
  • OSX Mojave
  • Ruby 2.5.1
  • MySQL (yeah, yeah I know; not apologizing)

Here is what I did (you should know that I hit issues with older versions of Yarn and Node so I've included updating them as part of this):

  1. Started a terminal session.
  2. Verified my ruby version:

    ruby –version

  3. Verified my rails version:

    rails –version

  4. Upgrade Yarn:

    curl -o- -L bash
  5. You can either start a new terminal to get your path exports correct (it is set on Terminal start) or simply do this:

    export PATH="$HOME/.yarn/bin:$HOME/.config/yarn/global/node_modules/.bin:$PATH"

  6. Upgrade node:

    brew upgrade node

  7. Upgrade Ruby to 2.6.2 (not required but I figured why not):

    rvm install 2.6.2

  8. Change to the new ruby:

    rvm use ruby-2.6.2

  9. Generate a new application:

    rails new lauck –database=mysql

  10. If you got anxious and generated a new application prior to installing a new ruby then, you would need to update the Gemfile to reflect the Ruby version and bundle install.

Note: I've named this new test application after one of my favorite librarians.
