Cannot open exception db file for reading, even with read permission

[huyiwen]

Hi, I have encountered the same issue as #48 but I failed to fix it by giving the db file permission:

l /Users/huyiwen/.files2rouge/data/WordNet-2.0.exc.db
.rwxrwxrwx 12k huyiwen  6 Jul 21:43 /Users/huyiwen/.files2rouge/data/WordNet-2.0.exc.db

I'm working on macOS 12.4 and Python 3.8.12. I installed the module under the instruction of README. The error occurs both in command line and python script:

Preparing documents... 0 line(s) ignored
Running ROUGE...

Thanks a lot for your help!
