为什么vue-cli-3无法构建，“找不到'wepack'？”

Question

由于最近在尝试运行npm run build时遇到此错误，表示在mini-css-extract-plugin中找不到webpack。我不知道是什么原因引起的。

我最近创建了一个发布分支，但是与build仍然有效的master分支相比，我没有太多更改（在package.json中）。但是几个星期前（在我的假期之前）它仍然有效，并且我对此问题一无所知。

这也是初始错误：

Error: Cannot find module 'webpack'
    at Function.Module._resolveFilename (module.js:538:15)
    at Function.Module._load (module.js:468:25)
    at Module.require (module.js:587:17)
    at require (internal/module.js:11:18)
    at Object.<anonymous> (D:\EnviDat\Frontend\envidat_frontend\node_modules\mini-css-extract-plugin\dist\index.js:8:39)
    at Module._compile (module.js:643:30)
    at Object.Module._extensions..js (module.js:654:10)
    at Module.load (module.js:556:32)
    at tryModuleLoad (module.js:499:12)
    at Function.Module._load (module.js:491:3)
    at Module.require (module.js:587:17)
    at require (internal/module.js:11:18)
    at Object.<anonymous> (D:\EnviDat\Frontend\envidat_frontend\node_modules\mini-css-extract-plugin\dist\cjs.js:3:18)
    at Module._compile (module.js:643:30)
    at Object.Module._extensions..js (module.js:654:10)
    at Module.load (module.js:556:32)

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。

我遇到以下错误时结束了：

Module build failed (from ./node_modules/thread-loader/dist/cjs.js):Thread Loader (Worker 0)webpack with invalid interface loaded as resolver

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

我不知道为什么会发生错误，以及如何更改才能使其再次起作用

完整的package.json在这里：https://github.com/EnviDat/envidat_frontend/blob/release/Navigation_integration/package.json

和vue.config.js：

module.exports = {
  publicPath: './',
  assetsDir: './static',
  runtimeCompiler: true,
  css: {
    modules: false,
    sourceMap: true,
  },
  pluginOptions: {
    storybook: {
      allowedPlugins: ['define'],
    },
  },
};

我该如何更改依赖项或配置以使其重新构建？

尝试运行

npm i -g webpack webpack-cli 

查看是否有效
