ionic2初始化错误的解决办法

Posted on by king2088

第一次使用ionic2，安装的过程中就出现了问题，查看相关的问题，刚开始以为是python安装不正确，后来又以为是c ++ 环境没有配置好，折腾了好几个小时。我靠，基本都已经快要让我失去信心了，但是一不小心我发现了一个错误Cannot download “https://github.com/sass/node-sass/releases/download/3.13.1/win32-x64-46_binding.node”就是这个下载失败了，原来是sass环境搭建错误啊。搞得我浪费了那么多时间！先来看看错误提示吧。

ionic start myApp --v2

解决的办法也很简单哦。
直接用迅雷下载https://github.com/sass/node-sass/releases/download/3.13.1/win32-x64-46_binding.node，然后设置环境变量。
变量名称：SASS_BINARY_PATH，变量值：c:\ccc\win32-x64-46_binding.node，这样就可以了。基本就解决了问题了！
