我正在尝试安装[email protected]，但是出现以下错误。安装Ionic2
我不介意我是否必须重新安装node或cordova。有没有人有任何想法，我需要做什么来成功安装[email protected]？
感谢

UPDATE
我发现我下载Python现在看来得到进一步。但我有一个错误，说我需要.NET Framework 2.0 SDK。当我从微软下载exe时，它什么都不做。
任何想法如何安装.NET Framework 2.0 SDK？

他们”基本上向你解释问题。阅读错误信息，它不能在你的PATH上找到'python2'。安装python。问题是否持续？看看这个问题http://stackoverflow.com/questions/37411607/command-python2-not-found – Ivaro18
谢谢。我现在正在寻找安装'Python'。我看到'Python 3.5.2'是最新版本。我应该安装吗？或者“Python 2.7.12”？ – Richard
