所以我为angular5做了一个教程，并且按照指示我首先安装了node / npm，然后在最后我安装了angular cli ghpages，git（win64）并将我的项目上传到github。一切都运作良好。
然后我尝试为角度素材做另一个教程，使用此命令时出错：
npm install @angular/material @angular/cdk --save
以下是它给我的错误日志：

updated 2 packages in 11.873s
在视频中它添加了116个软件包，对我来说它只更新了2个，这就是我的选择。 我注意到我得到的一个错误是“错误：找不到：python2”，所以我决定检查我应该拥有的python。
然而，python -v也给了我错误，所以我决定重新安装它。我第一次安装python2但仍然出错，所以我也安装了python3，但没有用。
这是python 2的日志：

所以基本上，我不知道我做错了什么，但没有什么工作正常。我相信我已经超越了我的头脑所以任何帮助都会受到欢迎...... 我只是希望python / node / angular / git按预期工作。对不起，如果答案很明显，我对这一切并不熟悉，我只是按照我找到的教程。
