还是不行

One CLI for webpack must be installed. These are recommended choices, delivered as separate packages:

 - webpack-cli (https://github.com/webpack/webpack-cli)

   The original webpack full-featured CLI.

 - webpack-command (https://github.com/webpack-contrib/webpack-command)

   A lightweight, opinionated webpack CLI.

We will use "npm" to install the CLI via "npm install -D".

Which one do you like to install (webpack-cli/webpack-command):

按照大神的方法出现了这个问题，是什么原因怎么破？我试着安装了webpack-cli后报以下错误

Installing 'webpack-cli' (running 'npm install -D webpack-cli')...

厉害了，问题已经解决

可以,已解决

这个可以，已解决。

是webpack升级到4以后的问题

可以，解决了

1，修改package.json中代码

将老师编辑的 

"build": "webpack --config webpack.config.js"

修改为

"build": "webpack --mode development"

2，修改webpack.config.js中代码

顶部添加

const {

VueLoaderPlugin

} = require('vue-loader');

将【module】中新增【css】以及末尾添加【plugins】

修改为：

module: {

rules: [{

test: /.vue$/,

loader: 'vue-loader'

}, {

test: /.css$/,

use: ['vue-style-loader', 'css-loader']

}]

},

plugins: [

new VueLoaderPlugin()

]
