我正在使用pdflatex来Ubuntu将 latex 文件转换为 pdf 文件。
我正在随机生成的 UUID 路径上转换同一个文件，如下所示：
/tmp/crawler-downloads/fc2071e4-63f7-4c12-b750-9ea21cd103fe/sample.tex
在python中的用法：
process = Popen(['pdftex',
'--output-directory',
os.path.dirname(input_file_path),
'-interaction',
'nonstopmode',
input_file_path],
stdout=PIPE,
stderr=PIPE)
process.communicate(timeout=90)
在命令行上运行此行：
pdftex -interaction nonstopmode sample.tex
有时转换成功，有时转换失败。
在生成的日志文件中我可以看到这个错误：

日志的末尾写道：

long?

问题真的是路径太长吗？我觉得很奇怪，它无法处理这个问题。
有没有其他解决方案可以修复它而不改变文件路径？
