来自Python的Perl脚本调用错误

Question

当cmd是手动运行时，它可以正常工作，但是当从linux上的另一个程序运行时，它会在日志中给我一个错误。任何想法都将不胜感激。谢谢

在日志中检查日志文件时出现此错误。在

更新-

现在我得到一个diff错误-

^{pr2}$

Answer 1

您指示execvpe查找名为perl /home/josh/scripts/deluge/sorttv.pl的可执行文件。你可以想象，它没有找到它。在

您所做的相当于在shell中输入以下内容：

'perl /home/josh/scripts/deluge/sorttv.pl' ...

/home/josh/scripts/deluge/sorttv.pl应作为参数传递。而不是

^{pr2}$

你想要吗

args = ('/home/josh/scripts/deluge/sorttv.pl', ...)
os.execvpe('perl', args, env)

Answer 2

在python中调用函数时，需要将参数与命令分开提供。如您所见，execvpe的第一个参数应该是execvpe，参数/home/josh/scripts/fludge/排序应该是第二个。在
