ERROR in multi common Module not found: Error: Cannot resolve module 'react-router' in /path-to-project/app-name @ multi common

Question

希望我能得到一些帮助。我正在使用 electron (Atom Shell) 和 react 和 webpack 来构建 UI。当我运行 npm run build 在 package.json 文件中时

 "scripts": {
    "start": "electron main.js",
    "build": "webpack --progress --profile --colors",
    "watch": "webpack-dev-server --hot --inline --progress --colors"
  },

在运行宁npm run build我得到

> electron-quick-start@0.0.1 build /Users/Mavericks/Documents/apps/electron-quick-start
> webpack --progress --profile --colors

    |     ^

我知道第三个错误（ERROR in ./lib/main.js）是基于 babel 没有编译 ES6 代码。我的主要问题是为什么我要得到其他人

ERROR in multi common
Module not found: Error: Cannot resolve module 'react-router' in /Users/Mavericks/Documents/apps/electron-quick-start
 @ multi common

ERROR in multi common
Module not found: Error: Cannot resolve module 'alt' in /Users/Mavericks/Documents/apps/electron-quick-start
 @ multi common

我在提问之前做了什么 我删除了 node_modules 文件夹和运行 npm install..... 仍然出现相同的错误。

提前致谢。

这些错误说明您还没有安装相应的模块。运行 npm install --save alt react-router.
