过几个小时，或者几天就好了

试试npm cache clean 清下缓存看看 不行，就切官方源吧

cnpm sync 就可以吧（请自行参阅 cnpm 主页）

@AntSworD 过几个小时果然好了。 @coderfox cnpm sync是不可以的。

@pluswave @coderfox 是因为源上的模块包已经更新了，shasum校验也是新的了，但是cdn上的缓存没更新，下载下来的包还是旧的，只能等cdn刷新缓存

@AntSworD @coderfox 我弄错了，是公司这边的CDN缓存问题，实际上一直没有解决。我当时以为解决的时候是晚上回家了，CDN换了一个地址。

@pluswave 嗯，是阿里在你公司那块的cdn服务器没更新
