无法在 Windows 中安装 ionic

Question

参考堆栈溢出link中已经发布的问题，我只是跟进了ionic的基本安装过程，但突然之间出现了这个奇怪的错误。

我尝试了以下步骤作为安装过程

• 已安装node.js 最新7.2.1 v - 安装成功
• npm install -g cordova - 安装成功
• npm install -g ionic@1.7 - 失败。

附上捕获的日志以供参考。 npm-debug.log

好像你没有安装python，先安装python，

如果python存在，则由set PYTHON=C:\Python27\Python.exe设置路径，如果python安装在默认路径，否则将其更改为python所在的位置。
