我的 TeX 文件相当大pgfplots。我使用的是 TeXstudio 和 PdfLaTeX。我的 PdfLaTeX 命令如下所示
pdflatex.exe -synctex=1 -src-specials -interaction=nonstopmode -enable-write18 -main-memory=50000000 -extra-mem-top=50000000 -extra-mem-bot=50000000 -pool-size=5000000 -buf-size=5000000 %.tex。当我想编译 TeX 文件时，我收到错误 (main.log)：尽管我增加了主内存，但! Package tikz Error: Sorry, the system call 'pdflatex -enable-write18 -halt-on -error -interaction=batchmode -jobname "graphics/pgfplots/main-figure4" "\def\t ikzexternalrealjob{main}\input{main}"' did NOT result in a usable output file ' graphics/pgfplots/main-figure4' (expected one of .pdf:.jpg:.jpeg:.png:). Please verify that you have enabled system calls. For pdflatex, this is 'pdflatex -sh ell-escape'. Sometimes it is also named 'write 18' or something like that. Or m aybe the command simply failed? Error messages can be found in 'graphics/pgfplo ts/main-figure4.log'. If you continue now, I'll try to typeset the picture.图中的日志文件告诉我 。! TeX capacity exceeded, sorry [main memory size=3000000]. \pgfplotslistpushbackglobal ...e \t@pgfplots@toka
我已经在\usepgfplotslibrary{external}使用\tikzexternalize[shell escape=-enable-write18]
我做错了什么？有没有办法扩展pgfplots库本身的内存？我必须坚持使用 PdfLaTex，因为我使用的模板仅与 PdfLaTex 兼容（因此 LuaLaTex 不是选项）。
更有趣的是，在我的 MWE 中，我可以处理大约 1MB 大小的文件，而在我的完整文档中，我只能处理大约 120kB 大小的文件。设置是相同的。
