ローカルのcircleCI CLIで通るrspecがオンラインでは通らない問題

Question

前提

docker、mysqlを使用しrailsでポートフォリオ用のweb appを作ろうとしており、githubにpushした際に自動でcircleCI上でrspec、rubocopが回るようにしようとしております。
circleCI CLIを用いてローカルでテストを実行した際には現れなかったエラーが出て困っております。
また、ローカルのdocker内でrspecを回した場合もエラーは表示されません。

実現したいこと

ここに実現したいことを箇条書きで書いてください。

試したこと

Failure/Error: __send__(method, file)

LoadError:
  cannot load such file -- /home/circleci/project

という記述からbundle install周りがうまくいっていないのかと思い試行回数を増やすために
circleCI CLIでローカルに行った場合再現できなくなったため原因の検討がつかず困っております。
参考にしたサイトなどではorbを使わずに実装していることが多いためそちらで行うべきなのでしょうか？

また、rubyのorbのsample(https://circleci.com/developer/ja/orbs/orb/circleci/ruby)
において、
orb
node: circleci/node@x.y
の使用及び

- node/install-packages:
          cache-key: yarn.lock

の実行が行われており、postgresを使用する場合に行う操作かと思い省いているのですが
これが今回のエラーに関わる可能性はあるのでしょうか？

Answer 1

とりあえず自力で解決いたしました。
この質問者様のコードから、昔のorbではテストが通るようでしたのでorbを昔のバージョン(1.1.0)に下げてみたところ
rspecが通るようになりました。
circleci -> cimgへのイメージの変化は関係ありませんでした。
また、mysqlやnode関連のインストールもしていますがその時点ではエラー内容に変化ありませんでした。

結論

cannot load such file -- /home/circleci/project
の原因はorbのせいだと考えていますがもし勘違いであるとお気づきの方がいらっしゃいましたらお教えいただけると幸いです。
