新人提问，安装formidable的时候出现了npm ERR! registry error parsing json

我的node版本是 node-v0.10.16-x86.msi 安装formidable的时候出现了下面这样的错误(我已经修改registry的url)，请高手指点下下该如何解决

E:\development\nodejs\node_modules\npm>npm install formidable -g npm http GET http://registry.npmjs.vitecho.com/formidable npm http 502 http://registry.npmjs.vitecho.com/formidable npm ERR! registry error parsing json npm http GET http://registry.npmjs.vitecho.com/formidable npm http 502 http://registry.npmjs.vitecho.com/formidable npm ERR! registry error parsing json npm http GET http://registry.npmjs.vitecho.com/formidable npm http 502 http://registry.npmjs.vitecho.com/formidable npm ERR! registry error parsing json formidable@1.0.14 E:\development\nodejs\node_modules\npm\node_modules\formidable

是不是formidable的版本有问题呢，请高手指点，感激不尽~
