Bug: Incorrect path passed to os.makedirs in file.py causing "Permission denied" (Linux) #821
Description
Hi,
OS Linux.
I made sure the user is correct by adding a few print statements to
/home/libretranslate/LibreTranslate/env/lib/python3.12/site-packages/cachelib/file.py
right before the line where it crashes.
os.makedirs(self._path) is passed "db/sessions" parameter, which seems to be a relative path?
If yes, relative to what?
I tried to run it in plain Python (under libretranslate user) and it gives the same error:
import os
os.makedirs("db/sessions")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<frozen os>", line 215, in makedirs
File "<frozen os>", line 225, in makedirs
PermissionError: [Errno 13] Permission denied: 'db'
Python 3.12.3.
Also set all permissions manually in libretranslate user home dir to libretranslate:libretranslate.
Backtrace (with my print/debug output):
os.makedirs(self._path) originally was at line 80.
