我对 LaTeX 还很陌生，到目前为止，整个环境对我来说相当令人困惑，所以如果我做了一些愚蠢的事情，请容忍我！
希望下面的 MWE 是一个很好的起点：

目前，我看到三个错误。
- /usr/local/texlive/2017/texmf-dist/tex/latex/biblatex/biblatex.sty，第 13046 行包 biblatex 错误：未找到样式‘ext-authoryear’。l.13046 \RequireBibliographyStyle{\blx@bbxfile}。无法找到参考书目样式“ext-authoryear”。
- /usr/local/texlive/2017/texmf-dist/tex/latex/biblatex/biblatex，第 13047 行包 biblatex 错误：未找到样式‘ext-authoryear’。请参阅 biblatex 包文档以了解解释 l.13047 \RequireCitationStyle{\blx@cbxfile}。无法找到引用样式“ext-authoryear.sty”。
- l.61\DeclareInnerCiteDelims{footcite}{\bibopenparen}{\bibcloseparen}错误消息顶行末尾的控制序列从未被 \def'ed。
请注意，每当我将样式改回基本 biblatexauthor year样式时，引用和脚注都可以正常工作，只是命令DeclareInnerCiteDelime似乎没有执行任何操作，而且year我的脚注中仍然缺少括号。
非常感谢任何指点和/或评论！谢谢

这里的技巧已经隐藏在有用的错误消息中，但多亏了 Ivan，我才终于意识到我必须去哪里寻找。
本质上的ext-biblatex风格是2018-03-08仅 TeX Live 版本及以上支持这是软件包的公开发布日期biblatex-ext。由于我在在线 LaTeX 编辑器 shareLaTeX 中使用 TeX Live 2017，因此ext找不到定义的样式。快速更改设置以使用更高版本的 TeX Live（在我的情况下是 2020.1），一切都按预期进行！
