我对nodejs完全不熟悉。我试图让nodejs在我的Windows 2008盒子上工作，以安装Karma，我将用于TDDing我的AngularJs代码。到目前为止，我已经完成了以下步骤
Install using Chocolatey ==> npm is not recognised Install using 64-bit nodejs installer from nodejs.org ==> npm is not recognised At this stage, running where npm gives me c:\User\<Username>\AppData\Roaming\npm which has nothing in it I figure out that nodejs is installed in C:\Program Files\nodejs. Opening a command prompt in this directory makes npm work fine. So I added C:\Program Files\nodejs to PATH only to get the same error again that npm is not recognized One of the github issues on nodejs repository says that I need to restart the machine and it would fix. But that has not helped so far I do see a Node.js icon in my Start -> Programms mennu which takes me to nodejs console but not sure what to do with that.
在这个过程中，我是否错过了任何重要的步骤?
Edit
我发现如果我从程序文件中打开“Nodejs命令提示符”，那么npm是可以识别的。如何让它在正常的命令提示符下工作?
Edit
在node之后，我开始在另一个应用程序中遇到类似的问题。我在超级用户上发布了这个问题，正如被接受的答案所正确指出的那样，我在我的PATH中有一个额外的引用，这导致了引用后添加的所有路径出现问题。我有一种感觉，一些Chocolatey安装添加了这句令人不安的引用，但我只是不确定是哪一个。
