安装Ionic2

Question

我正在尝试安装ionic@2.0.0-beta.11，但是我得到了以下错误。

如果我必须重新安装node或cordova，我并不介意。有人知道我要做什么才能成功安装ionic@2.0.0-beta.11吗？

谢谢

npm install -g ionic@2.0.0-beta.11

我发现我下载了Python，现在它似乎有了进一步的发展。但我有个错误，说我需要.NET Framework 2.0 SDK。当我从微软下载exe时，它什么也不做。

关于如何安装.NET Framework 2.0 SDK的任何想法

尝试以下命令(以管理员身份打开cmd )：

npm install --global --production windows-build-tools

这将安装所需的所有组件。
