Webpackのインストール[email protected]が必要です

Question

UbuntuとDebianの両方にwebpackをインストールしようとすると問題が発生しました。「npm install -g webpack 」を実行すると、次のエラーが表示されます。私はアップデートとアップグレードを行いましたが、IveはDebianとDebianの間でオペレーティングシステムを入れ替えました。かなり混乱しました。

Answer 1

ノードバージョン4.2.6は4.3より下です。 Webpackには4.3以上のノードのバージョンが必要です

可能であれば、ノードのバージョンを更新してください。

$ sudo apt-get install curl 
$ curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash – 
$ sudo apt-get install -y nodejs 

またはnnpmのライブラリを使用してください。
