## 二、报错原因 ##

**webpack5和html-webpack-plugin4二者之间的版本兼容问题。**

## 三、解决方案(我用的是第二种) ##

### 第一种是将webpack的版本降到4点几的版本 ###

**首先卸载之前安装的webpack**

npm uninstall webpack -g

**之后再安装指定的webpack版本**

npm install webpack@4.44.2 -g

**在安装html-webpack-plugin**

npm i --save-dev html-webpack-plugin

**在webpack.config.js中设置：**
