Dockerで何もしていないのにRubyのバージョンが変わった時の対処法

Posted at

エラー内容

突然、Dockerで環境構築していたアプリで、

terminal
Your Ruby version is 2.7.4, but your Gemfile specified 3.1.2

となり、何もできなくなった。。。

解決方法

vscodeの拡張機能「Remote - Containers」を使っていたので、そこの「Rebuild Container」をクリック!

ビルドされるのを待って、再度試すとエラー解決していました👏

正常にビルドされていなかったことが原因っぽいです。
