在这里有个前提，在我同事的电脑上代码是可以跑通的，到我把代码拉下来就开始报这些错

出现问题时用了几个解决思路
1.  查询报错Error: getaddrinfo ENOTFOUND 96f0e031-f37a-48ef-84c7-2023f6360c0a.bspapp.com
2.查询报错Module build failed (from ./node_modules/@dcloudio/vue-cli-plugin-uni/packages/sass-loader/dist/cjs.js):
3. 因为报错都有/deep/所以这个也查了一下
4. 查询报错SassError: expected selector.

由于上面的解决思路是按照先后顺序发生的，所以就我运行的项目，在尝试第四个的时候问题解决了，
尝试1的时候搜索了一些相关的文章，有关于这个问题怎么解决的，挑着可能有用的尝试了以下方法：
1). 在控制台
yarn add node-sass@4.14.1 --dev
yarn install
2). 按照官方文档配置下载安装方式配置 | uView 2.0 - 全面兼容 nvue 的 uni-app 生态框架 - uni-app UI 框架
3). ping 报错的网址通不通换网络
ping 96f0e031-f37a-48ef-84c7-2023f6360c0a.bspapp.com（这个网址在我电脑和他人电脑上都ping 不通，换网络也没用）这个方法舍弃，后来想了一下，要是可以通就不会报这个错了。
以上三个方法都没解决我在运行过程中遇到的问题，针对不同的环境可能就会有效果。但是我尝试的第三种方案建议舍弃

尝试2在查询过程中没有发现具体有效的办法，所以觉得解决问题的方向是不对的，就舍弃了这个思路
尝试3在查询的时候也试过了，在Vue中scss不识别/deep/，尝试屏蔽了/deep/也无效，其实当时已经很接近问题解决方案了，但是走到这放弃了
深度选择器>>>,/deep/和::v-deep都是>>>的别名，在scss中不识别/deep/, 可以使用::v-deep，我在hx中安装的sass插件，一些预处理器(Sass）是不识别>>>的，所以需要改成/deep/或者::v-deep,但是scss中不识别/deep/所以尝试使用::v-deep。
这也就是我在尝试4的时候发现的，在这个文章中找到了原因：sass 中使用/deep/报错 SassError: expected selector. - 简书
把/deep/改成 ::v-deep后问题解决了
