Could not open output GFF in result/result2/ because No such file or directory

[qkqk-hub]

Hello, I am executing a command error:

command:
perl ../CRISPRCasFinder.pl -in /data_alluser/QK/NewMAGs/ALL_represent_AND_MINE_MAG_GTDB-tk/Archaea_fna/MGYG000000522.fna -out result/result2 -so ../sel392v2.so

error:

This problem occurs when I generate the result in a two-tier directory:

1. -out result/result2：An error is reported
2. -out result：Program run successfully

Thank you very much for your answer!
