Why this error happend? nodejs Error: write EIO

Question

I made a webApp with nodejs + mongodb + Backbone on window7-32bit, everything goes fine until yestoday. but I got this error this morning:

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: write EIO
    at errnoException (net.js:883:11)
    at Object.afterWrite (net.js:700:19)

I googled around but no luck, I tried update node, and then got this error:

npm ERR! Error: write EIO
npm ERR!     at errnoException (net.js:883:11)
npm ERR!     at Object.afterWrite (net.js:700:19)
npm ERR! If you need help, you may report this log at:

npm ERR! node -v v0.10.4
npm ERR! npm -v 1.2.18

why this error happened suddenly? any hint about it?

Thanks for any ideas.

I have just been playing with Unicode support in Windows command prompt, using the code-page 65001 I can't get npm to install, giving me the above error. Changing the code-page to 850 chcp 850 and running the exact same npm command it then works fine.

Thus your problem could very well be related to the encoding your environment is in.
