我试图用cpanm来安装MIME :: Base64，它给了我sys / types.h缺失的错误。 然后我尝试安装libc6-dev，失败并显示错误消息

The following information may help to resolve the situation: The following packages have unmet dependencies: libc6-dev : Depends: libc6 (= 2.13-38+deb7u8) but 2.19-11 is to be installed Depends: libc-dev-bin (= 2.13-38+deb7u8) E: Unable to correct problems, you have held broken packages. 我希望有人知道一个解决scheme，可以帮助我
似乎你正试图在Debian 7系统（2.13-38 + deb7u8）上安装Debian 8 libc6（2.19-11）。 检查你的/etc/apt/sources.list是否有任何奇怪的条目。
