Upgrade from 3.9.2 to 4.1.1 issues

[Mark Jenks]

I was running python 2 before, and upgraded to python 3.   Never had an issue until I upgraded to 4.1.1.  

What am I missing?

# python --version

Python 3.7.6

pyserial is installed.

[root@server bin]# ./wee_device

Using configuration file /home/weewx/weewx.conf

Using Vantage driver version 3.2.1 (weewx.drivers.vantage)

pip install pyserial

[Mark Jenks]

I just did this.  No change..

dnf install python3-pyserial

[Mark Jenks]

This works...

[weewx@server ~]$ python

[John Kline]

I’m not sure what OS you are on, but would you try:

python3

import serial

That works.  See above.   It's python3

[Mark Jenks]

I just did a full stop and start, and I get this.   Permissions?

I have this set..  I tried tty and usb for SUBSYSTEM..

[root@server rules.d]# more vantage.rules

# udev rules for davis vantage connected via usb

#ACTION=="add", SUBSYSTEM=="tty", ATTRS{idVendor}=="10c4", ATTRS{idProduct}=="ea60", SYMLINK+="vantage"

# use this rule if you are using systemd

Hi Mark,

Does the user, that weewx is running as, belong to the group dialout ?

On linux, a user that wants to use a serial port must belong to the
dialout group.

This still applies even if the serial port is via a USB interface.

regards

Tim

[Mark Jenks]

Never had to do that before..   But just added weewx go dialout group and no change.

If you use pip to install things while in the WeeWX directory /home/weewx, it will see the setup.cfg file there, then try and install things in the WeeWX directory system. Take a look in /home/weewx/bin and see if serial ended up in there.

If so, delete it, then cd to some other directory, such as your home directory, then try installing. Make sure you use the python3 version of pip:

cd ~

python3 -m pip install pyserial

I completely removed pyserial using pip and dnf.
Same thing.  Maybe something to do with rules.d?  I tried tty and usb both, and get the same thing.

Did you look in /home/weewx/bin?

Ugh, I looked right at it and didn't even see it.  I looked into /home/weewx, but only glanced into bin.
Removed and it's working!   

Thank you!

👍

I can't tell you how many times this has happened to me.
