解压出现：

End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of AIR.zip or
AIR.zip.zip, and cannot find AIR.zip.ZIP, period.

如何解决


[解决办法]
所有的Archive都有这个问题么？ 怎么感觉是AIR.zip包下的有问题，md5正确么？
