本文解决了一个Node.js应用程序中无法找到socket.io模块的问题。错误信息显示为Error: Cannot find module 'socket.io'。解决方法是在包含node.js文件的目录下执行npminstallsocket.io命令，确保在正确的位置创建了node_modules文件夹。

That's all. Then I try to use socket.io with this line:

var io = require('socket.io').listen(app);
And it output an error:

Error: Cannot find module 'socket.io'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Module.require (module.js:364:17)
    at require (module.js:380:17)
    at Object.<anonymous> (F:\nodejs\chat.js:8:10)
    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)

    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)

I've tried all suggested method like cleaning cache, reinstalling nodejs or changing socket.io module path. Unfortunately, all of those solutions didn't solve this problem.

This terrible error killed my whole day. I greatly appreciate any help.

解决方法：

Try to execute npm install socket.io in the folder where your node.js file is (where you require the module). npm creates a folder node_modules wherever you execute npm install socket.io and you probably didn't do this in the correct folder.

npm install supervisor -g did work because -g is the global flag and you can basically do that anywhere.
