在linux上使用unzip解压一个.zip文件时，如果遇到下面这样的错误：
Archive: common_library.zip
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 common_library.zip or
common_library.zip.zip, and cannot find common_library.zip.ZIP, period.
原因有两种：
1) 以ASCII格式上传了.zip文件
2) .zip文件大小超过了2G。
