当我用 LaTex 编译文件时
\documentclass[12pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\begin{document}
Test
\end{document}
我在日志文件中收到此消息错误：

misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

看起来虽然您拥有最新的源（来自tlmgr update），但是格式文件并未使用这些源重建。
fmtutil-sys --all
将在 texlive 中重建格式文件。
