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... ||
