Upgrade to version 4.1.1-1 from version 3 Fails to start

[themet...@gmail.com]

I am running weewx on a Raspberry Pi upgrade using apt upgrade, and realise that it now runs on Python 3.

I have made sure that in the /etc/default/weewx I have python3.

I am using the new weewx.config with the relevant items for MySQL database and my Vantage Pro2 system as before.

I have installed various missing modules including python-serial, python3-configparser, python3-mysqldb, python3-pymysqld

I get this error:

Aug 23 20:04:41 picluster python3[22080]: weewx[22080] CRITICAL __main__:     ****    File "/usr/share/weewx/weedb/mysql.py", line 15, in <module>
Aug 23 20:04:41 picluster python3[22080]: weewx[22080] CRITICAL __main__:     ****      import pymysql as MySQLdb
Aug 23 20:04:41 picluster python3[22080]: weewx[22080] CRITICAL __main__:     ****  ImportError: No module named 'pymysql'
Aug 23 20:04:41 picluster python3[22080]: weewx[22080] CRITICAL __main__:     ****  Exiting.

But I have pymysql installed, If I go to a python3 prompt and issue this:

>>>import pymysql

It does not show an error, so why is weewx complaining??

OK, so I rebooted. Now I have an error which I did have before, then it disappeared:

This happens with all of the following settings in the [[wx_binding]] section

manager = weewx.manager.DaySummaryManager
# manager = weewx.manager.WxDaySummaryManager
# manager = weewx.wxmanager.WxDaySummaryManager
What is going on here? I should not have updated the system...... Grrrr!!!!

Hi,

Appreciate you said 'This happens with all of the following settings in the [[wx_binding]] section' but could you humour us and and set manager = weewx.manager.DaySummaryManager under [DataBindings] [[wx_binding]] in weewx.conf. Restart WeeWX and if an error appears in the log post the log from when WeeWX was started through until the error appears making sure you capture the entire WeeWX startup. If the error is the same as above could you also post a wee_debug report, before posting the wee_debug report do check the output for usernames, passwords, API keys etc, wee_debug is pretty good at obfuscating these but its not perfect.

Well, well, well, Gary. Indulge you I did, and the first attempt failed with the same error when I issued this command:

Then I tried this without any change to the weewx.conf file at all:

service weewx restart

and blow me down it started!!!!!

I am really grateful for your reply. I was tearing what hair I have on top of my bald head trying to figure this one out!

the two valid provided values for ‘manager =‘ are weewx.manager.DaySummaryManager (preferred) or weewx.wxmanager.WXDaySummaryManager (deprecated, and note it is not WxDay…) so you might want to check it is working properly….
