我正在使用 Texworks 写一篇论文，但在使用某些特定命令时遇到了问题，加载包时会出现一些错误。
第一个错误：
! Package xkeyval Error: `Optionen' undefined in families `Gm
进而：
! Package biblatex Error: Incompatible package 'natbib'
我的代码是：
% !TeX spellcheck = en_US
% !TEX encoding = UTF-8 Unicode

据我了解，第一个错误是由于包含（选项）而引起的，因为其他先前的包可能已上传几何包。第二个错误似乎是不兼容 - 但我有点不知道该怎么做，因为我无法下载包并真正开始工作。
提前致谢，
