Invalid configuration object. Webpack has been initialized using a configuration object that does no

配置webpack打包报错：

Invalid configuration object. Webpack has been initialized using a configuration object that does not match the API schema.- configuration.devtool should match pattern "^(inline-|hidden-|eval-)?(nosources-)?(cheap-(module-)?)?source-map$". BREAKING CHANGE since webpack 5: The devtool option is more strict. Please strictly follow the order of the keywords in the pattern

百度说是版本不兼容问题，就是假设你webpack版本是5，但是用到的插件版本还是4，不兼容webpack5。

所以此时你可以选择降级webpack，

npm install webpack@4.41.5

之后又报错：

TypeError: Cannot read properties of undefined (reading ‘tap’)

还是百度的答案：将webpack降级后，html-webpack-plugin需要和webpack保持同一个版本，这里我执行了：npm install html-webpack-plugin@4.41.5会报错，去了npm官网，只需要@4就行了

npm i --save-dev html-webpack-plugin@4

最后解决了问题。
