セットアップ

Homebrew手順

１. Homebrewインストール

Homebrew総集編を参照

Terminal

$ brew --version
Homebrew 2.2.2
Homebrew/homebrew-core (git revision f246; last commit 2020-01-14)
Homebrew/homebrew-cask (git revision 7585; last commit 2020-01-15)

rbenv + Bundler手順

１. rbenvをインストール

Terminal

$ brew install rbenv ruby-build

==> Pouring readline-8.0.1.mojave.bottle.tar.gz
==> Caveats
readline is keg-only, which means it was not symlinked into /usr/local,
because macOS provides the BSD libedit library, which shadows libreadline.
In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only.

For compilers to find readline you may need to set:
  export LDFLAGS="-L/usr/local/opt/readline/lib"
  export CPPFLAGS="-I/usr/local/opt/readline/include"

For pkg-config to find readline you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/readline/lib/pkgconfig"

==> ./install.sh
==> Caveats
ruby-build installs a non-Homebrew OpenSSL for each Ruby version installed and these are never upgraded.

To link Rubies to Homebrew's OpenSSL 1.1 (which is upgraded) add the following
to your ~/.bash_profile:
  export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@1.1)"

Note: this may interfere with building old versions of Ruby (e.g <2.4) that use
OpenSSL <1.1.

後編の `bundle install`で ld: library not found for -lmysqlclientが出る場合

mysql-clientをbrew installする
今回は便宜上mysql本体もインストールします

A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
  /usr/local/etc/openssl@1.1/certs

and run

openssl@1.1 is keg-only, which means it was not symlinked into /usr/local,
because openssl/libressl is provided by macOS so don't link an incompatible version.

If you need to have openssl@1.1 first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.bash_profile

For compilers to find openssl@1.1 you may need to set:

５. rbenvで認識しているすべてのRubyバージョンを一覧表示

Terminal

$ rbenv versions
* system (set by /Users/webmaster-patche/.rbenv/version)
  2.6.5

systemはMacに最初から入っているRubyを意味します

６. globalのRubyバージョンを変更

Terminal

$ rbenv global 2.6.5

$ rbenv versions
  system
* 2.6.5 (set by /Users/webmaster-patche/.rbenv/version)

７. rbenv init

Terminal

$ rbenv init
# Load rbenv automatically by appending
# the following to ~/.bash_profile:

eval "$(rbenv init -)"

８. プロファイルにinitを追記

Terminal

echo 'export PATH="~/.rbenv/shims:/usr/local/bin:$PATH"' >>  ~/.bash_profile
echo 'eval "$(rbenv init --no-rehash -)"' >>  ~/.bash_profile

$ source ~/.bash_profile

*尚、 7〜8の手順をしないと、 You don't have write permissions が発生します

Terminal

$ gem install bundler
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.

９. bundlerのインストール

Terminal

$ gem list bundler --remote

Docker手順

１. Brew経由でインストール

Terminal

$ brew install docker

２. バージョン確認

Terminal

$ docker --version
Docker version 19.03.5, build 633a0ea

３. 起動確認

Terminal

$ open /Applications/Docker.app

４. アクセス権付与

ログインユーザーのパスワード要求がされます

パスワード入力後、ボタンに文言がありませんが(汗クリックします

起動しました

５. セットアップ

まずは Reset to factory defaults で　rawフォーマットを行う

再起動します。この際に、権限付与のダイアログが表示されます

ただ、 Disk の情報を見る限り、デフォルトでrawフォーマットになっていると考えられる
リリースノートを見る限りでは、rawフォーマットについては2018年以降、記述がありません

６. メンテナンス

(*GB on disk) がDisk image sizeに限りなく近くなった場合、build時のゴミなどが溜まってきている可能性が高い

定期的に Reset disk image する必要がありますが、再度、ビルドし直しとなります。
