Node.JS - How to Run Node Command from any path?
提问by nfa379
I have installed the latest node.js from here. I see the %Path% variables have been set for Node.js. But, When i run node from C:\ , i get a "Node is not an recognized comman". But node command is working fine from "C:\Program Files (x86)\nodejs" path. Can i not run Node commands from C:\ or Say from an other path if i set the Env variables right? Please help. I am running a Win7 X64.
我从安装了最新的node.js这里。我看到已为 Node.js 设置了 %Path% 变量。但是，当我从 C:\ 运行节点时，我得到一个“节点不是公认的命令”。但是 node 命令在“C:\Program Files (x86)\nodejs”路径下工作正常。如果我正确设置了 Env 变量，我不能从 C:\ 或从其他路径运行 Node 命令吗？请帮忙。我正在运行 Win7 X64。
Thank You, Faraaz

What happens if you run node --version? I have never tried node.js from windows but if that doesn't work there is something wrong with your paths.
如果你跑会发生什么node --version？我从未尝试过 Windows 中的 node.js，但如果这不起作用，则说明您的路径有问题。
What do you get when you run echo %PATH%?
当你跑步时你会得到什么echo %PATH%？

I had the exact same problem, but in my PATH variable I had: C:\Program Files\nodejs\.
After changing it to C:\Program Files\nodejsI could access it from anywhere.
我遇到了完全相同的问题，但在我的 PATH 变量中我有：C:\Program Files\nodejs\. 将其更改为C:\Program Files\nodejs我可以从任何地方访问它。

You should check if the path C:\Program Files (x86)\nodejsis present in your %PATH. If not, add it via the system properties (persistent change). In any case, restart your command prompt, it'll reload the %PATHvariable. If you're lucky, it should work now :)
您应该检查路径C:\Program Files (x86)\nodejs是否存在于您的%PATH. 如果没有，请通过系统属性添加它（持续更改）。无论如何，重新启动命令提示符，它会重新加载%PATH变量。如果你很幸运，它现在应该可以工作了:)

Most likely it happens because there is no Node path in your PATH environment variable.
很可能是因为您的 PATH 环境变量中没有 Node 路径。
I see two ways to solve this
我看到有两种方法可以解决这个问题
- Just add Node path into the end of PATH.
- Reinstall Node as administrator
- 只需将节点路径添加到 PATH 的末尾。
- 以管理员身份重新安装节点
run 7-zip(or some file manager) with administrator privileges >> browse to node-installer.msi >> open it, install node >> enjoy
以管理员权限运行7-zip（或某些文件管理器）>> 浏览到 node-installer.msi >> 打开它，安装 node >> 享受

My Sublime was working with Nodejs fine. I could press Alt-R and see the output from Node in Sublime. Then at some point I upgraded Sublime. I now have version 2.02 build 2221 And at some later point I tried Alt-R and got this infamous message
我的 Sublime 与 Nodejs 一起工作得很好。我可以按 Alt-R 并在 Sublime 中查看 Node 的输出。然后在某个时候我升级了 Sublime。我现在有版本 2.02 build 2221 后来我尝试了 Alt-R 并收到了这条臭名昭著的消息
'node' is not recognized as an internal or external command
“节点”未被识别为内部或外部命令
But it had worked, so what changed?
但它奏效了，那么什么改变了？
The steps I took to fix it were to install git bash and then
我修复它的步骤是安装 git bash 然后
$ git clone https://github.com/tanepiper/SublimeText-Nodejs.git
$ cd SublimeText-Nodejs/
$ git checkout 095ba03344
Back in Sublime I clicked Preferences > Browse Packages. This opened up Windows Explorer with the folder:
回到 Sublime，我点击Preferences > Browse Packages。这打开了带有文件夹的 Windows 资源管理器：
C:\Users\me\AppData\Roaming\Sublime Text 2\Packages
I replaced the contents of the Nodejs folder with the git version. Re-started Sublime and then Alt-R sprang back into life.
我用 git 版本替换了 Nodejs 文件夹的内容。重新启动 Sublime，然后 Alt-R 重新焕发生机。
Other things that turned out to be irrelevant were changing the file Nodejs.sublime-settingsand tampering with system environment variables. The only thing that worked was 095ba03344as described here https://github.com/tanepiper/SublimeText-Nodejs/pull/39
其他无关紧要的事情是更改文件Nodejs.sublime-settings和篡改系统环境变量。唯一有效的是095ba03344，如此处所述 https://github.com/tanepiper/SublimeText-Nodejs/pull/39
