我正在尝试按照angularjs.org教程（https://docs.angularjs.org/tutorial）。它需要你安装和设置git，我在使一切工作时遇到一些麻烦。本教程的说明非常简单，所以不确定我哪里出错了。安装期间选择了所有默认选项。
在安装node.js和TRYING以安装项目所需的所有工具后，问题就开始了。我在git命令行和git bash中都试过这个（不确定区别是什么）。在安装node.js之后，教程说要将命令npm install放到其他工具中，而在git bash中你得到这个

现在我首先在Git CMD中尝试了这个，我得到了类似这样的东西npm WARN deprecated graceful-fs@3.0.8: graceful-fs version 3 and before will fail on newer node releases. Please update to graceful-fs@^4.0.0 as soon as possible.我刚刚在Git CMD中再次尝试过，现在看起来像是在bash中发生了同样的事情。我有节点版本5.6.0。
有人知道我应该从哪里出发吗？
好吧所以我最终做了@Oliver Queen发布的修复程序，除了我从GIT Bash而不是SDK 7.1（{sdk找不到我保存项目的目录，我认为因为我记得在git安装期间只能使用Git Bash而不是windows cmd吗？）。似乎工作，这是我得到的
npm install正如你在底部看到的那样我仍然得到

我要担心吗？
