Setting up a new Rails development environment on MAC M1/M2

Introduction

Hello buddy, if you are here, it is probably because you have just acquired a new computer equipped with a new chip from Apple, the M1/M2. Know that in addition to being a marvel of modern technology and engineering, this super machine is also capable of keeping you awake with a multitude of crazy, and sometimes inexplicable, problems that will prevent the correct installation of various software.

This guide assumes that the machine has not yet had any systems installed, and all the steps for installing them will be described here in the order in which they were done by me until I was successful in this endeavor.

This guide also assumes that you’re using zsh. If not, replace any references to .zshrc in the steps below with .bash_profile (if you’re using Bash) or the appropriate shell.

Implementation steps

Step #01

First, add the devise token auth gem to your Gemfile and run bundle to install it

Gemfile

gem 'devise_token_auth'

Prepare system for new installation

# Before start, make sure you've killed all old tmux servers that
# could be still running in the background
sudo killall -9 tmux

# Remove any previous installation
sudo apt-get -y remove tmux

Install needed dependences

	# Article for Dockerfile at ADD_URL_FOR_THIS
	# We're using the Ruby 2.3.1 base container and extend it
	FROM ruby:2.3.1

	# We install certain OS packages necessary for running our build
	# Node.js needs to be installed for compiling assets
	# libpq-dev is necessary for installing the pg gem
	# libmysqlclient-dev is necessary for installing the mysql2 gem
	RUN apt-get update && \
	apt-get install -yq \

	require 'csv'

	file = "#{Rails.root}/public/user_data.csv"

	products = Product.order(:first_name)

	headers = ["Product ID", "Name", "Price", "Description"]

	CSV.open(file, 'w', write_headers: true, headers: headers) do \|writer\|
	products.each do \|product\|

	heroku pg:backups capture

	heroku pg:backups public-url

	curl "http://[url]" > production.dump

	pg_restore --verbose --clean --no-acl --no-owner -h localhost -U myuser -d mydb file.dump

	# -----------------------------------------------------------------------------
	# This config is targeted for tmux 2.1+ and should be placed in ~/.tmux.conf
	# Read the "Plugin Manager" section (bottom) before trying to use this config!
	# -----------------------------------------------------------------------------

	# -----------------------------------------------------------------------------
	# Change the default prefix key from CTRL+b to CTRL+a
	# -----------------------------------------------------------------------------
	set -g prefix C-a
	bind C-a send-prefix

	ActiveRecord::Base.connection.tables.each do \|table_name\|
	ActiveRecord::Base.connection.reset_pk_sequence!(table_name)
	end
