Weewx won't run after fileparse install

[Ron Walker]

Fresh install of weewx 5.02 on Raspberry Pi running buster.  I attempted to instll the fileparse driver manually according to readme in the direcory.  When I attempt to start weewx, this the result:

ron@WeatherPi5:~ $ sudo systemctl status weewx

Any help would be greatly appreciated!

Where did you get the fileparse.py that you manually installed? If the 'readme in the direcory' you referred to is the readme in the fileparse directory then it has a mistake. For a manual install under a WeeWX v5.x package install you should copy fileparse.py as follows:

cd /etc/weewx/examples/flippers
sudo cp bin/user/fileparse.py /etc/weewx/bin/user

The fileparse.py that you are using is different to the version distributed with v5.0.2; the line that is throwing the error uses a python2 syntax for the print statement. Under python3 print is a function that requires the uses of brackets (hence the error). Have a look in /etc/weewx/examples/fileparse/bin/user, that directory contains the fileparse.py you should be using. The version number should be 0.9. If /etc/weewx/examples/fileparse/bin/user/fileparse.py contains a python2 print statement (rather than the python3 print function) then that is a bug. Interestingly, the last version of fileparse.py to include python2 print statements was included with WeeWX v4.0.0a3 (and it only had 120 lines); I have no idea how you have ended up with the fileparse.py that you have.

Gary,

You are correct.  I'm not sure how I got the older one, unless it came over with the customizations like extensions when I copied from my backup of previous version.  All is well!  Thank you for the hints!

Ron
