@ts1cos did you get updated?

[ts1cos]

yes, I had to uninstall it and reinstall it and then it worked

[Saentist]

How you uninstall it I can't

[jblance]

@Saentist - How did you install?
if you used pip, then pip uninstall mppsolar (or sudo pip uninstall mppsolar) should do it

With PIP i guess
pip install -e "git+https://github.com/jblance/mpp-solar.git#egg=mppsolar"

# whereis mpp-solar
mpp-solar: /usr/local/bin/mpp-solar

[jblance]

If installed with pip, pip should be able to uninstall Otherwise you'll need to delete the actual files `find / -name mppsolar` as root to see where (or look at the script pointed to by the whereis command) It's a pain, which I why I recommend pip installs now

To remove them all or?

[jblance]

If you are trying to clean up, yes Lots of src repos there so I assume at some point you have installed from src which can get messy fast If you are trying things out I suggest venv or docker to keep it isolated

great that you've figured it out

[Saentist]

great that you've figured it out another reason to use venv or docker

Venv complicated configuration for end user https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html
Docker 1.5gb extra space just to run it slower running extra memory usage

Native is best solution but python version selection when there is more then one is problematical.

---

Interesting solution will be using PyInstaller or Nuitka

[multilectical]

Hmmm, I just attempted to upgrade and ended doing a dist upgrade on raspbian, but now can only seem to get mppsolar running via venv which works. But can't figure out how to get the service started up again. Any direction here would be super appreciated.

I edited the path to where mpp seems to run in venv (/home/onion/venv/mppsolar/bin/mpp-solar) , but it's not working. Anyone have a good idea how to make this happen?

here's my service file. I think I need to prefix python under execstart possibly???

onion@raspberrypi:~ $ cat /etc/xdg/systemd/user/mpp-solar.service

but when I try it directly it works:

I got it working. Just in case it can help others while updating, what I did that I think fixed things after updating to the virtual environment (this: https://github.com/jblance/mpp-solar/wiki/Installation#using-a-virtual-environment ) :

source venv/mppsolar/bin/activate // enter the new virtual env
pip install systemd-python // install python systemd which wasn't yet installed in the virtual env

I also made put a file with the following where the previous mpp-solar used to live at /usr/local/bin/mpp-solar

#!/bin/bash
/home/onion/venv/mppsolar/bin/python /home/onion/venv/mppsolar/bin/mpp-solar

That just calls the virtual env version without having to enter that environment on the cli and might be enough to make the service work without the above step.

edit: replace any path with onion in it with to reflect the proper path in your own setup.

good news, thanks for the update - Ive added to the wiki
