3行で書くと

config.google_cloud.use_logging = false 等の設定を入れていると $ bundle install や $ rails test（minitest）が通らなくなることがあった¹
その設定をそのまま外したら通った
その設定を入れた理由の事象も解消されていたので恒久的に外したままで大丈夫そう

環境

Windows 10 Pro、Ruby3.2.2、Rails7.1.2

経緯

Gemfileの、主にGoogle Cloud絡みのものをガチャガチャ弄っていたらある時 $ bundle install や $ rails test（minitest）が通らなくなってしまいました。

実際に出たエラーはこんな感じ。

bundle installのエラー

rails s とかでも出るかもしれません

調べてみたらあまり情報はなかったんですが、古い情報ながら下記に行き当たりまして

話の本筋はだいぶ違うような気はするものの、どうも config.google_cloud.use_logging 辺りが怪しそう。
確かにgcloud CLI のインストール・セットアップ後、あらゆる rails コマンドで警告が出ていたため（下記記事と同事象）

これに倣って config/enviroments/ 以下の development.rb test.rb に下記の設定を入れていました。

config.google_cloud.use_logging = false
config.google_cloud.use_debugger = false
config.google_cloud.use_error_reporting = false
config.google_cloud.use_trace = false

ならば一旦こいつらを消してみようと、設定前の状態に戻してみたら

エラーは解消し、$ bundle install も $ rails test も通った
そして当初の警告も何故か表示されなくなっていた

ので、再現条件や発生理由等掘り下げていないですしその予定もないのですが
もし同じ事象で困っている方がいれば一助になれば幸い🙏ということで一応記事にしておきました。

詳細な再現条件は不明 ↩
