我刚刚更新到最新的 TeX Live（在 Mac 上，即sudo tlmgr update --self --all）no updates available，现在尝试在软件包中使用半粗体字体时出现错误libertine。我的 MWE 是
\documentclass{article}
\usepackage[semibold]{libertine}
\begin{document}
no body needed
\end{document}
当编译时（使用 PDF LaTeX）我得到下面的输出。 texdoc libertine仍然表明这是获取半粗体文本的正确方法，所以不要认为这个选项已经被贬低了。
任何线索都值得赞赏！
