コマンドで「npm install」を実行したのですが、エラーが出てしまいます。

Question

プログラミング学習中のものです。
Udemyで、Sassの学習をしているのですが、動画の指示どおりに学習のリソースをダウンロードして解凍し、そのリソースを全て作業ディレクトリにコピーして、コマンドでそのディレクトリに移動し、コマンドで「npm install」を実行したのですが、エラーが出てしまいます。VS codeのコマンドで同じことをやっても同じエラーですし、node_modules と package-lock.json を 削除してみましたが、それでもエラーです。
どうしたらいいでしょうか？
宜しくお願いいたします。

Answer 1

node-sassのインストールでエラーが発生しているようです。
node-sassとnode.jsのバージョンは厳しく依存しています。
package.jsonに記載されているnode-sassのバージョンを確認してみてください。

追記
見落としていましたが、pythonが見つからないエラーも見られますので、確認してください。

npm ERR! gyp verb `which` failed Error: not found: python2
npm ERR! gyp verb `which` failed python2 Error: not found: python2
npm ERR! gyp verb check python checking for Python executable "python" in the PATH

Nodeのバージョンをダウングレードしたら、解決しました。
