Ruby3.1 + Rails7でRSpecの検証環境を作る




OS macOS Monterey
MacBook Pro(14インチ、2021)
チップ Apple M1 Pro

Ruby 3.1.0 -> 3.1.0より古いとうまくいかない
Rails 7.0.1


M1 Macの初期状態だとopensslの設定がLibreSSLになっているので、切り替える必要がある

# openssl確認
$ openssl version
LibreSSL 2.8.3

# LibreSSLからOpenSSLに切り替える
$ brew install openssl
$ brew link --force openssl@3
Linking /opt/homebrew/Cellar/openssl@3/3.0.1... 5487 symlinks created.

If you need to have this software first in your PATH instead consider running:
  echo 'export PATH="/opt/homebrew/opt/openssl@3/bin:$PATH"' >> ~/.zshrc

$ echo 'export PATH="/opt/homebrew/opt/openssl@3/bin:$PATH"' >> ~/.zshrc

$ source ~/.zshrc
$ which openssl



$ mkdir test-app
$ cd test-app

$ bundle init
Writing new Gemfile to /path/to/project_name/Gemfile

$ vi Gemfile
# frozen_string_literal: true
source "https://rubygems.org"

git_source(:github) {|repo_name| "https://github.com/#{repo_name}" }

gem "rails"

$ bundle install --path vendor/bundle --jobs=4
  • bundle install オプション
    • gemをプロジェクト内で管理するために --path を vendor/bundleに指定
    • --jobs=4で並行処理でインストールできるらしい(多分速い)

    The 'rails new' command creates a new Rails application with a default
    directory structure and configuration at the path you specify.

    You can specify extra command-line arguments to be used every time
    'rails new' runs in the .railsrc configuration file in your home directory,
    or in $XDG_CONFIG_HOME/rails/railsrc if XDG_CONFIG_HOME is set.

    Note that the arguments specified in the .railsrc file don't affect the
    defaults values shown above in this help message.

    rails new ~/Code/Ruby/weblog

    This generates a skeletal Rails installation in ~/Code/Ruby/weblog.

今回はサクッと検証用のアプリが作ることを前提にするので、Asset Piplineを使う

  • rails new オプション
    • -B:ここでbundle installを行うとvendor以下に保存されないためskipさせる
    • -d:mysql:DBをmysqlに変更。デフォルトはsqlite3
    • -M:Mailer関連の項目をスキップ
    • -C:websocket使う予定がないのでActionCableをインストールしない
    • –skip-test:Rspecを使う予定なので、minitestはスキップ
    • --skip-turbolinks: turbolinksはいれない
$ bundle exec rails new . -d mysql -B -M -C --skip-test --skip-turbolinks
Gemfileを上書きしていいか聞かれる → yes

rails newの際にbundle installが走るが、vendor/bundleにインストールされないため、スキップ
なぜかsprockets-railsがインストールされないので、ここで手動でbundle install して入れる

$ bin/rails s
Could not find gem 'sprockets-rails' in locally installed gems.
Run `bundle install` to install missing gems.

$ bundle install
$ bin/rails db:create
$ bin/rails db:migrate
$ bin/rails s



group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
  gem 'factory_bot_rails' # 追記
  gem 'rspec-rails' # 追記
$ bundle install
$ bundle exec rspec

こっちの方がオススメだよ! 等のアドバイス等ありましたら、よろしくお願いします🙏
