由于最近在尝试运行npm run build时出现此错误，原因是在mini-css-extract-plugin中找不到webpack。我不知道是什么原因造成的。
我最近创建了一个发布分支，但是与build仍然可以使用的master分支相比，我没有太多更改（在package.json中）。但是几个星期前（假期之前）它仍然有效，我无法理解这个问题。

我已经尝试通过npm install手动将依赖项安装在node_modules \ mini-css-extract-plugin文件夹中，但是随后我得到了其他无法加载的依赖项。安装它们时。

到那时我迷路了，我可以在线查找所有内容，因此我重新安装了所有的node_modules，结果仍然相同。另外，我尝试使用npm ci进行全新安装，仍然是同样的问题。

答案 0 :(得分：1)
因此，我删除了package-lock.json，npm告诉我缺少的依赖项。我安装了这些。当我运行构建时，它需要有关eslint-loader的更多信息。
总结：
npm install --save-dev webpack html-webpack-plugin typescript vue-loader babel-loader eslint-plugin-import eslint-import-resolver-webpack
和
npm run build
屈服
DONE Build complete. The dist directory is ready to be deployed.
虽然并没有真正回答这个问题：//
答案 1 :(得分：0)
尝试运行
npm i -g webpack webpack-cli
看看是否有效
