javascript - React-native: [NODEMON] `babel-node src` を起動すると、「npm run dev」の実行中に「babel-node」が内部コマンドまたは外部コマンドとして認識されない

Question

nodemon を使用して、React Native アプリで hello world の例を開始しています。しかし、 「npm run dev」を実行すると「babel-node」コマンドを認識しないため、アプリがクラッシュし続けます。エラー出力は次のとおりです。

[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,mjs,json
[nodemon] starting `babel-node src`
"babel-node" is not recognized as an internal or external command,
operable program or batch file.
[nodemon] app crashed - waiting for file changes before starting...

このエラーをどのように修正しますか?
