我收到此错误：

If that doesn't work, type X <return> to quit.
authoryear-icomp.cbx.tex出现错误的行是：
\ExecuteBibliographyOptions{labeldate,uniquename,uniquelist,ibidtracker=constrict,
pagetracker,sortcites,autocite=inline}
这是 MWE（几天前它可以工作，今天我用 MiKTeX 2.9 更新了软件包）：

答案1
在 3.5 版中biblatex，
\ExecuteBibliographyOptions{labeldate,uniquename,uniquelist,ibidtracker=constrict,
pagetracker,sortcites,autocite=inline}
将导致以下形式的错误
! Package keyval Error: No value specified for labeldate.
什么曾是该选项labeldate已重命名为labeldateparts。该选项要求 Biber 提供labelyear字段和朋友并通过提供年份消歧义extrayear。
现在有了一个新的labeldate选项，但它现在需要一个参数（在上面的例子中，该选项没有附带参数，因此会导致错误）。此选项控制labelyear和朋友给出的日期的格式。
请参阅 v 3.5 部分变更文件。
使用标准样式时，您不会遇到此问题，因为它们已更新为使用正确的选项。如果您使用自定义样式，请通知作者以便她可以更改此设置。
正如评论中所讨论的，这里的问题是一个本地文件，authoryear-icomp.cbx.tex其中包含一个旧副本，authoryear-icomp.cbx其中仍使用旧选项。加载的是这个文件而不是（现有的）标准文件，这导致了问题。删除该文件解决了这个问题。
