当尝试使用 ETbb 包编译（即使是最简单的）文档时，例如：
\documentclass{article}
\usepackage{ETbb}
\begin{document}
Test.
\end{document}
我收到涉及缺少字体度量文件的错误：
line 3: Font T1/ETbb-TLF/m/n/10=ETbb-Regular-tlf-t1 at 10.0pt not loadable: Metric (TFM) file not found. \begin{document}
line 3: Font \T1/ETbb-TLF/regular/n/10=nullfont not loadable: Metric (TFM) file not found. \begin{document}
该日志还包含以下内容：
Sorry, but miktex-makemf did not succeed. The log file hopefully contains the information to get MiKTeX going again: C:\Users\⟨username⟩\AppData\Local\MiKTeX\miktex\log\miktex-makemf.log
Couldn't open `ETbb-Regular-tlf-.cfg' hbf2gf (CJK ver. 4.8.4) […]
Couldn't open `nullfo.cfg' hbf2gf (CJK ver. 4.8.4) […]
Process finished with errors
其中miktex-makemf.log有重复的条目（在本例中指的是虚拟字体度量文件ETbb-Italic-tlf-swash-t1.vf和ETbb-Regular-tlf-t1.vf），例如：

我正在使用 MiKTeX，这个问题在常规发行版和预发行版中都存在。刷新字体映射文件、重新安装软件包等都无济于事。几周前，使用 ETbb 的文档编译仍然顺利，因此问题可能是由最近的一些更新引起的。
如果问题不仅限于我的特定安装，这可能表明 MiKTeX 中存在打包错误或冲突。在我填写之前错误报告，也许更专业的人可以看看并确认问题是由 ETbb 包或 MiKTeX 的其他组件引起的，并且没有明确的用户端解决方案。
