"Parameters must be numbered consecutively."重新安装系统后，当我尝试使用带有无衬线字体的 siunitx 时收到一条奇怪的错误消息。
这是一个最小的示例代码：
\documentclass{article}
\renewcommand\familydefault{\sfdefault}
\usepackage{siunitx}
\begin{document}
test
\end{document}
我使用的是 Fedora 16，安装了（非完整）Texlive 2011，而我以前的系统上安装了 Fedora 15 和完整 Texlive 2011，一切都编译正常。此外，当我使用字体命令删除该行时，不会出现错误。
