这是package.json，已经参考了老师源码，但是运行时还是报错：

ERROR  Failed to compile with 5 errors                                                                                                                                                                                      10:08:58

These dependencies were not found:

* base/scroll/scroll in ./~/babel-loader/lib!./~/vue-loader/lib/selector.js?type=script&index=0!./src/components/recommend/recommend.vue

To install them, you can run: npm install --save api/recommend api/config base/slider/slider base/loading/loading base/scroll/scroll

按照提示去安装依赖，结果又报错提示：

npm ERR! code ENOLOCAL
npm ERR! Could not install from "base\slider\slider" as it does not contain a package.json file.

npm ERR! A complete log of this run can be found in:

请问老师，这要怎样解决？

显然你要在 package.json 里添加 better-scroll、 axios 这些依赖库啊

  非常感谢！

找到原因了， 我的 package.json 里是有添加 better-scroll、 axios 这些依赖库的，但是执行 npm install 不知道为什么就这几个依赖库一直没有安装上，多安装了几次然后才安装上，可能是因为网络原因吧。后面遇到这问题的同学可以换 淘宝的 cnpm 试试。另外，感谢老师的解答！

你有配置 api、base 这些的 alias 吗

Answer 4

提问者 半晴雨滴 2018-04-03 12:11:17

resolve: {
  extensions: ['.js', '.vue', '.json'],
  alias: {
    '@': resolve('src'),
    'common': resolve('src/common'),
    'components': resolve('src/components'),
    'base': resolve('src/base'),
    'api': resolve('src/api')
  }
},

这要配置，然后再运行还是报错。

 ERROR  Failed to compile with 4 errors                                                                                                                                                                                      11:35:09

These dependencies were not found:

* axios in ./src/api/recommend.js
* better-scroll in ./~/babel-loader/lib!./~/vue-loader/lib/selector.js?type=script&index=0!./src/base/slider/slider.vue, ./~/babel-loader/lib!./~/vue-loader/lib/selector.js?type=script&index=0!./src/base/scroll/scroll.vue
* jsonp in ./src/common/js/jsonp.js

To install them, you can run: npm install --save axios better-scroll jsonp

试过删掉所有插件再重新 npm install后运行还是这样报错。

我跟着视频一步步来的，但是视频里面有些地方要加哪些文件没有说明白诶，对比源码才知道少了哪些文件，不过有些文件有变动的话对比起来很麻烦，请问老师有每个章节未完成的源码吗？就是每个章节视频开始的时候的素材。
