Windows 已安装 node.js 但未找到 npm [英] Windows -installed node.js but npm not found

问题描述

我认为 npm 会在 Windows 上与最新的 node.js 安装程序一起自动安装.但是，当我尝试在命令控制台中使用 npm 时，出现以下错误

I thought npm is automatically installed with the latest node.js installer on Windows. However when I try and use npm in the command console I get the following error

C:npm install socketio

module.js:340
    throw err;
          ^
Error: Cannot find module 'C:\Users\foo\node_modules\npm\bin\n
pm-cli.js'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:906:3

我检查了并且 npm 确实存在于 nodejs Program Files 目录中.那么这是PATH环境问题吗?如果是这样，我该如何解决，以便我可以在任何打开命令控制台窗口的地方使用 npm?

I checked and npm DOES exist in the nodejs Program Files directory. So is this a PATH environment issue? And if so, how do I resolve so I can use npm anywhere I open a command console window?
