我正在基于FROM pandoc/ubuntu-latex镜像的 docker 容器中运行 pandoc，它运行良好。但是，每次运行时，我都会得到kpathsea: Running mktexpk ...似乎需要额外时间的步骤，每次我运行该 pandoc 命令时。
输出内容如下...
kpathsea: Running mktexpk --mfmode / --bdpi 600 --mag 1+0/600 --dpi 600 tcrm1095
mktexpk: Running mf-nowin -progname=mf \mode:=ljfour; mag:=1+0/600; nonstopmode; input tcrm1095

mktexpk: /root/.texlive/texmf-var/fonts/pk/ljfour/jknappen/ec/tcrm1095.600pk: successfully generated.
在我的Dockerfile尝试中，我运行了 kpathsea 在日志输出中生成的相同命令：
# create the fonts to save time each time a user will use them?
RUN mktexpk --mfmode / --bdpi 600 --mag 1+0/600 --dpi 600 tcrm1095
在创建图像期间它似乎运行良好，但它似乎并没有改变 pandoc 结果中的任何内容——kpathsea 再次运行。
我如何设置docker镜像以便tcrm1095.tfm可以看到现有文件（或者避免mktexpk每次都执行该步骤）？
编辑我在正在运行的docker容器的shell中验证了它的/root/.texlive/texmf-var/fonts/pk/ljfour/jknappen/ec/tcrm1095.600pk存在。
编辑2使用 shell 在 docker 容器中搜索显示有
/opt/texlive/texdir/texmf-dist/fonts/tfm/jknappen/ec/tcrm1095.tfm和
/usr/share/texlive/texmf-dist/fonts/tfm/jknappen/ec/tcrm1095.tfm，但 pandoc 仍在生成它们。也许我在图像中缺少环境变量？
答案1
我部分找到了答案。我的 pandoc makefile 没有使用更新docker image，使用RUN命令生成tfm文件。一旦我修复了 makefile 以使用较新的 docker 镜像，该kpathsea命令就不会重复。
但是，我仍然不确定为什么默认映像找不到.tfm安装在ec（tlmgr）包中的文件。
答案2
我也遇到了类似的问题，但仅限于引擎pdflatex！
使用时--pdf-engine=xelatex或 --pdf-engine=lualatex它工作正常。
