正准备学 ionic，然后各种问题，貌似都是因为 node 版本太新了？

问题一

Error: `libsass` bindings not found. Try reinstalling `node-sass`?

尝试的解决方案是跟着 sass 官方教程：Building on Mac OS X做的，但依然出现同样的错误提示。 我知道我肯定已经装了 libsass 的，但 binding 这是怎么设置？ export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig 也是设置过了的。

而且

npm ls node-sass

问题二

gyp ERR! stack Error: `make` failed with exit code: 2

完整版本是

乱七八糟试了很多，比如什么

sudo npm i -g node-inspector --unsafe-perm npm install contextify

但这个帖子有人说『there appears to be an issue with the subdependency contextify installing on node v4. 』好吧，看来版本太新就是坑啊！

要不我还是暂时先卸载 v4.1.1，用回 v0.12.7 吧……好惨…… 呜呜呜，再也不随便升级了……
