方法将"html-webpack-plugin"版本由 "^4.2.0"改为 "^3.2.0",

npm uninstall html-webpack-plugin

npm install html-webpack-plugin@3.2.0 -D

原因尚不清楚

下面这个一样道理，感觉出现这种bug,就是版本问题

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 i -D webpack-cli
-> When using yarn: yarn add -D webpack-cli
