我在论文上使用了带有Miktex的TexStudio，并且需要外部化所有创建的tikz图形。我处理了很多帖子，但无法弄清楚为什么我不能外部化我的代码。我使用pdflatex.exe -synctex=1 -interaction=nonstopmode --shell-escape %.tex进行编译，但也尝试使用write18。
这是图形日志之一的输出：
The command '\includegraphics []{\AM@currentdocname }' has been optimized away.
Use '/tikz/external/optimize=false' to disable this.
! Undefined control sequence.

! Package tikz Error: Sorry, the system call 'pdflatex -shell-escape -halt-on-e
rror -interaction=batchmode -jobname "figures/Masterarbeit-figure87" "\def\tikz
externalrealjob{Masterarbeit}\input{Masterarbeit}"' did NOT result in a usable
output file 'figures/Masterarbeit-figure87' (expected one of .pdf:.jpg:.jpeg:.p
ng:). Please verify that you have enabled system calls. For pdflatex, this is '
pdflatex -shell-escape'. Sometimes it is also named 'write 18' or something lik
e that. Or maybe the command simply failed? Error messages can be found in 'fig
ures/Masterarbeit-figure87.log'. If you continue now, I'll try to typeset the p
icture.
See the tikz package documentation for explanation.
我还可以补充一点，就是我可以在Windows文件系统中看到pdf文件一秒钟，然后再消失
