“npm 常见问题"在 Windows 7 上失败(“spawn ENOENT"错误) [英] "npm faq" fails on Windows 7 ("spawn ENOENT" errors)

问题描述

我已经使用最新的安装程序在 Windows 7 上安装了 node.js.它似乎有效，我可以从控制台(cmd 或 PowerShell)调用 npm 和 node，但我不断收到错误.

I have installed node.js on Windows 7 with their latest installer. It seemed to work, I can call npm and node from the console (either cmd or PowerShell), but I keep getting errors.

这里有很多关于windows上node.js的问题，但都提到了一些特定的代码.如果我选择更新生成器"，我将使用许多简单的命令获得生成 ENOENT"，例如 yo:

There are a lot of questions here about node.js on windows, but they all mention some specific piece of code. I'm getting the "spawn ENOENT" with a lot of simple commands, for instance yo, if I then pick "update generators" :

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: spawn ENOENT
    at errnoException (child_process.js:988:11)
    at Process.ChildProcess._handle.onexit (child_process.js:779:34)

即使 npm faq 也失败:

PS E:\www\something> npm faq
npm ERR! Error: spawn ENOENT
npm ERR!     at errnoException (child_process.js:988:11)
npm ERR!     at Process.ChildProcess._handle.onexit (child_process.js:779:34)
npm ERR! If you need help, you may report this *entire* log,
npm ERR! including the npm and node versions, at:
npm ERR!     <http://github.com/isaacs/npm/issues>

问题似乎是 node 使用了像 dir 这样的 unix 命令名称，而这些名称在 Windows 上不存在.一些博客文章提到使用 Cygwin，但主要用于构建 node.js，而不是调用它.nodejs 官方网站也没有提到 cygwin 是先决条件.

It seems that the problem is that node uses unix command names like dir, which do not exist on Windows. Some blog posts mention using Cygwin, but mostly for building node.js, not for calling it. The official nodejs website doesn't mention that cygwin is a prerequisite, either.

这是 npm-debug.log :

推荐答案

确保您的路径"系统变量中有 c:\Windows\System32.我遇到了这个确切的问题，这是我需要的修复.我一定是在过去的某个时候错误地取出了它.

Make sure that you have c:\Windows\System32 on your 'Path' System Variable. I was having this exact problem and this was the fix I needed. I must have taken it out in error sometime in the past.
