在 Ubuntu 网络服务器上使用 PHP 使用 pdflatex 执行 python 脚本？

Question

I am trying to execute a python script which uses pdflatex using php. Running the python script via command line works well.

But if I try to call it with php, it throws this error:

I can't write on file mylatex.log'. (Press Enter to retry, or Control-D to exit; default file extension is `.log') Please type another transcript file name: , Emergency stop ! ==> Fatal error occurred, no output PDF file produced!

So there seems to be a permission error.

This is the way I am trying to call the php file:

$command = escapeshellcmd('python3 /home/ubuntu/test.py');
$output = shell_exec($command);
echo $output;

The mylatex.log file has 777 permission as a test.

Is there a way to execute a python script which uses a library like pdflatex?

Answer 1

I solved the error by adding the php file to the same directory as the python file. Then it works. There seems to be a problem to call pdflatex in a different directory. Thanks for the help.
