为什么vue-cli-3无法构建，“找不到'wepack'”？

标签： javascript webpack vue-cli-3

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。

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 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。

当我遇到以下错误时，我结束了：

 @ multi ./src/main.js

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。

我无法弄清楚为什么会发生错误以及如何进行更改才能使其再次正常工作

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

还有vue.config.js：

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

我如何更改依赖项或配置以使其重新构建？

2 个答案:

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
