Railsでbcryptを使いたい

Question

railsでhas_secure_passwordを使いたい

rails tutorialを進めていたら、パスワードの部分でエラーが起きました（https://railstutorial.jp/chapters/modeling_users?version=5.1#sec-adding_a_secure_password）

gemfileでbcryptをコメントアウトして、bundle installを実行して、rails testをしようとしたらエラーになりました。

全く、お手上げの状態です。

試したこと

1. Gemfileを編集
2. bundle install
3. rails test
4. error!!!

Answer 1

なんかgem install bcrypt叩いたらできた。

よかったです

Answer 2

コメントアウトしてはいけません。
コメントであったのをコメントでなくした、のですよね。
コメントアウトは　コメントにして掃き出す　ことをいいます。

で、
wrong architecture だと言ってます。
Macだと
＃ Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
これが悪さしているのでは？？
「コメントアウト」してみてください

コメントアウトの使い方を間違えていました。正しくは「gemfileでbcryptのコメントを外して」ですね...

早速、'tzinfo-data'の行を「コメントアウト」してみたのですが、やはり同じエラーが起きます。エラー文も同じでした。
