preface

之前遇到几次 node-sass 安装失败， 又遇到一次， 本次记录下吧

现象

个人感觉 本次错误跟之前的不一样
我的是 下载 404 错误， 之前的方式都尝试了， 本地也强制清除了缓存

解决方案

1. $ npm install -g mirror-config-china

取自 taro 的官方方案

虽然用了 安装了国内镜像源但是，还是同样的错误

2. npm install node-sass

更新了 sass 版本， 然后就可以了

总结

个人感觉是 node-sass 版本问题， 因为尝试过手动添加 npm registry taobao 镜像源
如果不可以的话，我还准备 使用 cnpm 直接安装 node-sass
