编译Book demo无法使用画图引擎

[unionepro]

已按照说明装好了gnuplot，graphviz等，并将其加入msys2 PATH环境变量，art，book, slide样例都能编译通过，但就是提示找不到画图引擎，而画图引擎在msys2中运行都是没有问题的，提示信息如下。 $ panbook book --style=elegantbook [NOTE] Welcome to PanBook!

所使用工具版本如下： $ gnuplot --version gnuplot 5.4 patchlevel 1

执行

$ which dot
/mingw64/bin/dot

看下有结果没

可以直接安装 msys2 版本的 graphviz

pacman -S mingw64/mingw-w64-x86_64-graphviz

[unionepro]

之前用的是windows下的gnuplot和graphviz，which dot都能显示。现在安装了msys2的gnuplot和graphviz，问题还是和之前一样。

$ which gnuplot /mingw64/bin/gnuplot

$ which dot /mingw64/bin/dot

cd test/lua-filters/dot2image
make latex

看看结果

[annProg]

按照以下代码 修改 extensions/plot/plot.lua ，然后执行，看看输出的结果

diff --git a/extensions/plot/plot.lua b/extensions/plot/plot.lua

按照上述方法修改后之前找不到的程序的问题消失了，但是编译到最后出现了如下错误： WARNING No valid name object found. WARNING Could not find a value in dictionary object. WARNING Didn't find "endobj". ERROR pdf_link_obj(): passed invalid object.

不过我根据dockfile，在WSL1 Linux下使用各个程序的linux版本成功配置好了环境，可以成功编译各个demo，包括各种plot扩展。 不想折腾msys2了，非常感谢耐心解答。

另外，根据我的折腾，使用新版本的pandoc和texlive也会有各种问题，texlive 2019和pandoc 2.9.x是可以的。
