I can't seem to figure out why my forest externalization fails. It always works properly on the first compile, and if I clear any temporary files from my directory, but otherwise making any change to the tree and trying to recompile fails entirely with the following error:
./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.
Here is a MWE:
\documentclass{article}
\usepackage[linguistics, external]{forest}
\usetikzlibrary{external}
\tikzexternalize
\begin{document}
Forest:
\begin{forest}
[VP
[V]
[NP]
]
\end{forest}
\end{document}
And I'll include the full log, in case there's something I'm missing:

./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.
