npm run dev 失敗

[Malarkey-Jhu]

scripts 中已經添加這行：
"dev": "webpack-dev-server --devtool eval --progress --colors --content-base build",

但terminal還是顯示錯誤，好像是要叫我裝webpack
但按照他給我的提示npm install webpack-cli -D
之後還是出錯

以下是報錯信息，有人知道怎麼解決嗎

The CLI moved into a separate package: webpack-cli.
Please install 'webpack-cli' in addition to webpack itself to use the CLI.
-> When using npm: npm install webpack-cli -D
-> When using yarn: yarn add webpack-cli -D

請問是不是裝新版的babel webpack之後 這些方法都無效了?
