使用webpack命令打包时,报错TypeError: Cannot read property 'presetToOptions' of undefined的解决办法

我只安装了webpack,没有安装webpack-cli,第一次输入webpack打包时,提示

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.
We will use "npm" to install the CLI via "npm install -D".
Do you want to install 'webpack-cli' (yes/no):

输入yes后报错

Error: Cannot find module 'webpack-cli'
Require stack:

requireStack: [

]
}

解决办法:输入命令npm install webpack-cli -g全局安装一下webpack-cli

再次运行webpack命令打包,出现新错误

解决办法:根据错误提示信息,打开node_modules\webpack-cli\bin\cli.js,第137行,把const statsPresetToOptions = require("webpack").Stats.presetToOptions;中间Stats下标的这个.删掉。

保存后再次运行webpack就成功了!
