# Do any other automated setup that you need to do here

bin/setupはbundle installを実行するもので、その他のセットアップ処理を追加する場合は、こちらを利用しましょう。

bin/setupスクリプトが導入されました。これはアプリケーションの初期設定時に設定を自動化するためのコードの置き場所となります。

vim ./bin/setup

#!/usr/bin/env bash
set -euo pipefail
IFS=$'\n\t'
set -vx

bundle install

# Do any other automated setup that you need to do here

#!/usr/bin/env ruby

require "bundler/setup"
require "sample_project"

# You can add fixtures and/or initialization code here to make experimenting
# with your gem easier. You can also use a different console, if you like.

# (If you use this, don't forget to add pry to your Gemfile!)
# require "pry"
# Pry.start

require "irb"
IRB.start
