There is a lot of documentation on both, so you can just pick one that seems like you'll be more comfortable with. You'll probably want something more robust like MySQL or PostgreSQL. Chances are you won't want to use it because it's stored as a simple file on disk. Rails ships with sqlite3 as the default database. We're going to install sqlite3 from homebrew because we can't use the built-in version with macOS Sierra without running into some troubles. Installing Rails is as simple as running the following command in your Terminal: gem install rails -v 7.0.4.3Īnd now we can verify Rails is installed: rails -v Installing RailsĬhoose the version of Rails you want to install: Once you've done this, you can check and see if it worked: ssh -T should get a message like this: Hi excid3! You've successfully authenticated, but GitHub does not provide shell access. You want to copy and paste the output of the following command and paste it here. Git config -global user.email -t ed25519 -C next step is to take the newly generated SSH key and add it to your Github account. Replace the example name and email address in the following steps with the ones you used for your Github account. If you don't already have a Github account, make sure to register. We'll be using Git for our version control system so we're going to set it up to match our Github account. # Install yarn for Rails jsbundling/cssbundling or webpacker Then we can install the latest Node.js for handling Javascript in our Rails apps: asdf install nodejs 18.15.0 To install Ruby and set the default version, we'll run the following commands: asdf install ruby 3.2.1Ĭonfirm the default Ruby version matches the version you just installed. For Rails, we can install Ruby and Node.js for our frontend Javascript. Then we can install ASDF plugins for each language we want to use.

'$HOME/.asdf/completions/asdf.bash'' > ~/.zshrcĮcho 'legacy_version_file = yes' > ~/.asdfrc First you install asdf, and then add it to your shell:Įcho '. Installing asdf is a simple two step process. The reason we use ASDF over rbenv, rvm or others is that ASDF can manage other languages like Node.js too. Next we're going to be installing Ruby using a version manager called ASDF.
