Thanks,

It seems you are trying to run your script from the root cron job rather
than the user's cron job, and then trying to add a user site directory
to root's site path. From the docs:
|site.||ENABLE_USER_SITE|
Flag showing the status of the usersite-packages
directory.|True|means that it is enabled and was added
to|sys.path|.|False|means that it was disabled by user request
(with|-s|
<https://docs.python.org/3/using/cmdline.html#cmdoption-s>or|PYTHONNOUSERSITE|
<https://docs.python.org/3/using/cmdline.html#envvar-PYTHONNOUSERSITE>).|None|means
it was disabled for security reasons (mismatch between user or group
id and effective id) or by an administrator.

So perhaps a mismatch between UID/GID and EID is causing the whole
process to silently fail... ||
