発現状況

Windows 11で直にnpx create-next-app@latest [project-name] [options]をし、Next.jsのプロジェクトの開発
WSL Ubuntu 24.04.1 LTS環境での開発に切り替えたくなる。
SSHでリポジトリをクローン
リポジトリディレクトリでnpm installを実行→エラー

解決策

この方法だと完全に以前と同じバージョンのパッケージを読み込めるとは限りません。
package.jsonに書かれたものを参考にインストールされるため、バージョンにズレが生じる可能性があります。

理解してから行動したい人は以下をおすすめします。

package.jsonとpackage-lock.jsonのバージョン指定や必要性について

package-lock.jsonを削除

bash

npm install

を実行。

EINTEGRITYを日本語訳すると「誠実」という意味らしい。誠実エラー。
