meteor报错之:MongoDB had an unspecified uncaught exception.

今天测试的时候meteor报了个错

如下：

MongoDB had an unspecified uncaught exception.
This can be caused by MongoDB being unable to write to a local database.
Check that you have permissions to write to .meteor/local. MongoDB does
not support filesystems like NFS that do not allow file locking.

纠结了好久终于知道答案了，请确保你的硬盘有大于50G的预留空间，然后不要在内存小的磁盘分区里测试，要在内存充足的磁盘测试，(如果你报了这个错误，尝试换个磁盘去测试)
