Ruby3.1 + Rails7でRSpecの検証環境を作る

2022/02/07に公開約8,000字

Rails7系がリリースされたので、それでRSpecの検証環境を作るためにやったことをまとめる

開発環境

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

ハマりどころ

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
Ruby3.1.0からはOpenSSL@3が使えるが、3.1.0以前だとOpenSSL@1.1でないと動かない
Ruby2.4以下だとOpenSSL@1.1だと動かないので、更にダウングレードする必要があるらしい

# 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
/opt/homebrew/opt/openssl@3/bin/openssl

手順

$ mkdir test-app
$ cd test-app
$ rbenv local 3.1.0
$ ruby -v
ruby 3.1.0p0 (2021-12-25 revision fb4df44d16) [arm64-darwin21]

$ 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)

悩ましいRails new

rails7のnewのオプションは以下の通り

$ rails new --help

Description:
    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.

Example:
    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

動くのを確認

その後、Gemfileに

.
..
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
end
..
.
$ bundle install
$ bundle exec rspec
No examples found.

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🙏
