我想报告我的用户在使用我的 Python 软件创建的 TeX (LaTeX) 文件时遇到的错误。我正在使用spath3Andrew Stacey 的包来保存和重复使用路径。我不能使用我的设备重现此错误：
- 带有 MiKTeX 版本 3.141592653-2.6-1.40.25（MiKTeX 23.5）的 Windows 10
- Ubuntu 桌面 22.04.3 LTS 搭载 TeX Live 2022
我的用户有：
- Debian 与 TeX Live2020（TeX Live 2020/Debian）
pdflatex <filename>.tex我的软件只是在生成的文件上发出 Python命令.tex。他的设置在TeX Live 2020/Debian其文件末尾写入以下内容.log，但无法创建 PDF 文件：
! Package pgfkeys Error: I do not know the key '/tikz/spath/use', to which you
passed 'PMdusk', and I am going to ignore it. Perhaps you misspelled it.
See the pgfkeys package documentation for explanation.
Type H <return> for immediate help.
...
l.1033 [spath/use=PMdusk]
;
Here is how much of TeX's memory you used:
17965 strings out of 481252
373338 string characters out of 5915889
979391 words of memory out of 5000000
34602 multiletter control sequences out of 15000+600000
410105 words of font info for 46 fonts, out of 8000000 for 9000
14 hyphenation exceptions out of 8191
87i,8n,88p,1058b,1013s stack positions out of 5000i,500n,10000p,200000b,80000s
! ==> Fatal error occurred, no output PDF file produced!
然而 - 我不明白的是，当他手动运行时pdflatex <filename>.tex，它成功了，创建 PDF 文件。也许是可用内存的问题。由于他的设备在大西洋彼岸，我无法进行任何测试，也无法使用 TeX Live 重现它2022。
以下是示例文件中导致问题的关键部分.tex。抱歉，请注意，无论是我还是用户都无法将其归结为 MWE。感谢spath3Andrew Stacey 的帮助。
