最新版のDevise 4.7.3が入っている状態でOmniAuth 2.0.0をインストールすると、Rails Serverを起動することができない問題の対処方法

Dependabotに「Devise 1.9.1はSecurityに脆弱性があるからDevise 2.0.0にアップデートしよう」と通知をもらったので、ライブラリのバージョンをアップデートしようとしたところ、Rails Serevrが起動しなくなりました。😢

OmniAuthのバージョンは2.0.0なので、1.0.0より古いはずはない・・・🤔

原因

原因を調べてみたところ、

lib/devise/omniauth.rb のファイルに

github.com

unless OmniAuth::VERSION =~ /^1\./
  raise "You are using an old OmniAuth version, please ensure you have 1.0.0.pr2 version or later installed."
end

と書いてあって、OmniAuthのバージョンが 1.X.X じゃないとエラーになってしまうようでした。

対処方法（更新：2021/5/5）

Devise 4.8.0がリリースされているので、Gemのバージョンアップをすることで対処可能です。

github.com

バージョンアップの方法はGemfileに

gem "devise"

と記載して、ターミナルで

$ bundle update devise

を実行すれば更新されます。
