Setting up a dev environment for the first time

[matthewbadeau]

I recently replaced my Mac and am setting up a ruby dev environment for the first time. I have a rust and python dev dependencies installed, including XCode and homebrew. So not all steps may be applicable to everyone but here are the commands I needed to run to get a fully working dev environment on my Mac:

brew install ruby
brew install libarchive
# add to path as recommended by homebrew
echo 'export PATH="/opt/homebrew/opt/ruby/bin:$PATH"' >> ~/.zshrc
brew install postgresql
brew install mysql
brew install redis
brew install nodejs
brew install yarn
# fix for MySQL install
# https://stackoverflow.com/a/68154431
# Update the mysql2 version number to match the current value in the Gemfile
gem install mysql2 -v '0.5.6' -- --with-opt-dir=$(brew --prefix openssl) --with-ldflags=-L/opt/homebrew/opt/zstd/lib
bundle install
npm install # not sure if this was necessary
corepack enable
yarn set version stable
yarn install
npm run build
npm run build:css

Once all of the dependencies are installed, start your Postgres and Redis environments. Use separate terminal tabs and keep these alive while hacking away

/opt/homebrew/opt/postgresql@14/bin/postgres -D /opt/homebrew/var/postgresql@14

/opt/homebrew/opt/redis/bin/redis-server /opt/homebrew/etc/redis.conf

Run the migrations and then start the dev server

bin/rails db:migrate
bin/rails server -b 0.0.0.0 -p 3000 -e development

Good luck!

That's great, thanks! It's not required, but I'd recommend installing rbenv rather than ruby from homebrew, as that way you know you'll be on the correct Ruby version at all times (it picks up the value from the .ruby-version file and switches automatically). I've been meaning to set up a Brewfile so you can brew bundle all those dependencies, too.

This is great though! Might be a good idea to link it from the README in the development section, or update any of the details there that are wrong? I can't remember what is says tbh.
