我似乎无法弄清楚为什么我的森林外部化会失败。它在第一次编译时总是正常工作，如果我从目录中清除任何临时文件，但除此之外对树进行任何更改并尝试重新编译都会完全失败，并出现以下错误：
./Untitled.tex:15：软件包 tikz 错误：抱歉，系统调用“pdflatex -shell-escape -halt-on-error -interaction=batchmode -jobname "Untitled-forest-3" "\def\tikzexternalrealjob{Untitled}\input{Untitled}"”未产生可用的输出文件“Untitled-forest-3”（预期为 .pdf:.jpg:.jpeg:.png: 之一）。请确认您已启用系统调用。对于 pdflatex，这是“pdflatex -shell-escape”。有时它也被命名为“write 18”或类似名称。或者命令可能只是失败了？错误消息可以在“Untitled-forest-3.log”中找到。如果您现在继续，我会尝试排版图片。
以下是 MWE：
\documentclass{article}
\usepackage[linguistics, external]{forest}
\usetikzlibrary{external}
\tikzexternalize
\begin{document}
Forest:
\begin{forest}
[VP
[V]
[NP]
]
\end{forest}
\end{document}
我将附上完整的日志，以防我遗漏了什么：

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 'Untitled-forest-3.log'. If you continue now, I'll try to typeset the picture.

./Untitled.tex:15: Package tikz Error: Sorry, the system call 'pdflatex -shell-escape -halt-on-error -interaction=batchmode -jobname "Untitled-forest-3" "\def\tikzexternalrealjob{Untitled}\input{Untitled}"' did NOT result in a usable output file 'Untitled-forest-3' (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 'Untitled-forest-3.log'. If you continue now, I'll try to typeset the picture.
See the tikz package documentation for explanation.
Type H <return> for immediate help.
