问题 E:\webpack_vue\node_modules\clean-webpack-plugin\dist\clean-webpack-plugin.js:17 throw new Error(`clean-webpack-plugin only accepts an options object. See: ^
Error: clean-webpack-plugin only accepts an options object. See: https://github.com/johnagan/clean-webpack-plugin#options-and-defaults-optional at new CleanWebpackPlugin (E:\webpack_vue\node_modules\clean-webpack-plugin\dist\clean-webpack-plugin.js:17:13) at Object.<anonymous> (E:\webpack_vue\webpack.config.js:28:4) at Module._compile (module.js:573:30) at Object.Module._extensions..js (module.js:584:10) at Module.load (module.js:507:32) at tryModuleLoad (module.js:470:12) at Function.Module._load (module.js:462:3) at Module.require (module.js:517:17) at require (internal/module.js:11:18) at WEBPACK_OPTIONS (E:\webpack_vue\node_modules\webpack-cli\bin\convert-argv.js:115:13)
原因： webpack.config.js文件的配置有问题
解决办法 webpack4关于clean-webpack-plugin的写法为： plugins:[ new CleanWebpackPlugin(),//*** ],
