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:

  code: 'module_not_found',
  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！
