我直接说说我的问题。最近，在全新安装 Ubuntu 18.04 和 Mathematica 12 后，当我在 Lyx 中“使用 pdflatex 编译”文档时，出现以下错误。
!pdfTeX error: pdflatex (file lmmi7): Font lmmi7 at 600 not found
当我选择 Latin Modern Roman 字体时，问题就出现了，使用默认字体一切正常。有人能帮我吗？完整的日志是

答案1
您的主目录中有一个pdftex.map(请参阅日志文件的末尾)，它可能遮蔽了系统映射文件 (如果使用updmap而不是 ，则可能会发生这种情况updmap-sys。
将其重命名为 pdftex.mapori 并重试。
如果有效，您可以删除它以及其他地图文件/home/vahid/.texlive2017/texmf-var/fonts/map。
