webpack5使用cheapmoduleevalsourcemap报错

今天在构建demo时&＃xff0c;运行报错&＃xff0c;
Invalid configuration object. Webpack has been initialized using a configuration object that does not
match the API schema.
惯性思维先查找了下百度&＃xff0c;似乎没找到合适的解答。

于是&＃xff0c;耐心看了下报错提示&＃xff0c;大致是说webpack5的版本规范更严格了&＃xff0c;我的某段代码写的不规范。

报错我贴一下

根据提示&＃xff0c;改成eval-cheap-module-source-map,运行成功
