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。
