You have a fresh install of Mac OS X Catalina, and all the latest updates installed. Now you want to do some web development with Ruby on Rails.

I am writing this as a reference for myself, because I go through this process frequently.

Installations

Core Setup

  • Login to iCloud

  • Install Apps from App Store

  • Install iTerm2

  • Install Franz and Telegram

  • Install homebrew (which will also auto-install Apple’s “command line developer tools”) and some packages

    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install cmake libxml2 git hub asdf pinentry openssl libyaml libffi pkg-config autoconf readline coreutils

  • Install GnuPG using the GPG Suite, which provides a DMG based install, then:

    echo "test" | gpg2 --clearsign
git config --global user.signingkey BA3C3507
git config --global commit.gpgsign true
git config --global gpg.program gpg2

  • Jetbrains Toolbox: https://www.jetbrains.com/toolbox-app/

  • Google backup and sync: https://www.google.com/drive/download/backup-and-sync/

  • Dropbox: https://www.dropbox.com/install#downloaded

  • Install the latest Postgres.app.

pboling’s (My) Dotfiles

git clone git://github.com/pboling/dotfiles ~/Documents/src/dotfiles
ln -s $HOME/Documents/src/dotfiles ~/.dotfiles
cd ~/.dotfiles
rake install

NOTE: Quit and reopen iTerm to ensure all shells pickup the new paths, aliases, and other goodies.

asdf

Ruby

asdf plugin-add ruby https://github.com/asdf-vm/asdf-ruby.git
asdf install ruby 2.7.0
asdf global ruby 2.7.0

NodeJS

asdf plugin-add nodejs https://github.com/asdf-vm/asdf-nodejs.git
bash ~/.asdf/plugins/nodejs/bin/import-release-team-keyring
asdf install nodejs 12.11.1
asdf global nodejs 12.11.1

Yarn

For yarn I did not use the brew install because it would brew install other things, like nodejs, which I have through asdf.

curl -o- -L https://yarnpkg.com/install.sh | bash

Java

Next, run java, which prompts with a dialog that has a button “More Info” which takes you to a website where you can accept the license and download the Java .dmg file. You need the JDK, not the JRE, if you intend to run java command-line based tools.

Unable to find any JVMs matching version "1.7".
No Java runtime present, try --request to install.
∴ java
No Java runtime present, requesting install.

Once downloaded, open the .dmg (for me it was jdk-13.0.2_osx-x64_bin) and install.

SSH

Setup a new key, and add it to github.

chmod 600 ~/.ssh/config
chown $USER ~/.ssh/config

Postgresql

Install latest Postgres.app. I use the alternate installer on the downloads page that includes all supported versions (back to v9.4!)

ERRORS?

libxml-ruby

If you get an error installing the libxml-ruby gem:

bundle config build.libxml-ruby --with-xml2-config=/usr/local/opt/libxml2/bin/xml2-config --with-xml2-dir=/usr/local/opt/libxml2 --with-xml2-lib=/usr/local/opt/libxml2/lib --with-xml2-include=/usr/local/opt/libxml2/include

pg gem

If you use Postgres.app as I suggest above, and you are not using my dotfiles, then you will also need to add Postgress.app’s bin files to the PATH.

# Postgres.app Integration (for latest version)
export PATH="/Applications/Postgres.app/Contents/Versions/latest/bin:$PATH"

MySQL

If you get an error installing a mysql gem:

brew tap homebrew/services
brew uninstall mysql@5.7
brew install mysql@5.7
brew services list
brew services start mysql@5.7
brew link mysql@5.7 --force
mysql -V
bundle config build.mysql2 --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include
bundle install

NOTE: Mostly I followed this gist, and this gist.

compaudit

You may need to run compaudit and fix some directory permissions.

zsh compinit: insecure directories, run compaudit for list.
Ignore insecure directories and continue [y] or abort compinit [n]? y
/Users/pboling/.zshrc:12: command not found: rbenv

$ compaudit
$ sudo chmod g-w /usr/local/share/zsh/site-functions
$ sudo chmod g-w /usr/local/share/zsh
