我正在尝试将一些chemfig图表放入我的 tabularx。我已经让表格按照我想要的方式显示，但是我只是想将tikz绘图外部化以加快编译速度，结果遇到了错误。我遇到了这问题似乎是说，这简单地禁用了外部化的tabu必要性：是否存在类似的问题？他们给出的答案是，只需构建没有的表即可。\write18tikztabularxtabu
我对 Latex 也还很陌生，所以任何建议都非常感谢。谢谢。
tikzpicture此外，文档中还有另一个，但是我在编译之后添加了它，因为chemfig图表已经很慢，并且外部化没有问题。
这是我收到的错误：
Package tikz Error: Sorry, the system call 'pdflatex -shell-escape -halt-on-error -interaction=batchmode -jobname "tikz/output-figure0" "\def\tikzexternalrealjob{output}\input{output}"' did NOT result in a usable output file 'tikz/output-figure0' (expected one of .pdf:.jpg:.jpeg:.png:). Please verify that you have enabled system calls. For pdflatex, this is 'pdflatex -shell-escape'. Sometimes it is also named 'write 18' or something like that. Or maybe the command simply failed? Error messages can be found in 'tikz/output-figure0.log'. If you continue now, I'll try to typeset the picture.
以下是代码：
