ionic报错： Failed to load resource

隔了一天，才发现是代码写错了

出错的原因是在ts 文件中使用这样的定义

data: [] = ['高新区', '经开区', '其他园区'];

错误在于这个定义的类型，不能是 []，修改成 any就没有问题了

data: any = ['高新区', '经开区', '其他园区'];

醉了

不知道怎么搞的，突然ionic报错： Failed to load resource 导致项目启动不起来

该问题的最终解决办法是，把git项目重新克隆了一遍。所以今天并没有找到错误的原因

记录解决过程

发现这些丢失的文件都是在build目录下的

所以执行build命令，但是报错如下：

这个错误搞不懂，没搜到解决办法，于是想先删除了node_modules，在安装
重新运行npm install命令 安装

结果报错：从github下载超时

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-57_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-57_binding.node":

connect ETIMEDOUT 54.231.49.194:443

这里尝试了很多解决办法，终于可以下载了

但是再返回执行 build命令，还是报错，绝望了
