npmは複数のパッケージ名をインストールします

このコマンドを実行するとどうなりますか？

npm install --save-dev package1 package2

確かに複数のパッケージをインストールするわけではありませんが、必須のようです。 （たとえば https://www.browsersync.io/docs/gulp ）

私にとっては、次のエラーがスローされます：

依存関係として保存：

npm i package1 package2

dev-dependenciesとして保存：

npm i -D package1 package2

npm i --save-dev package1 package2

複数のパッケージをインストールすることは間違いありません

どうして？ package1およびpackage2をインストールし、devDependencies with --save-dev。

ドキュメント で述べたように、複数の引数を組み合わせたり、複数の種類の引数を組み合わせたりすることもできます。あなたの場合、レジストリに公開されている2つのパッケージ名を組み合わせています。

npm install -save module1 module2

例：npm install -save morgan chalk errorhandler lusca dotenv path mongoose

上記のコマンドは、morgan、chalk、errorhandler、lusca、dotenv、path、およびmongooseの最新バージョンをインストールします。
