No module named 'ArgConfigParse'

[daavid1995]

I tried to install PaperPi,
I got the message saying it was installed and I should configure it.
But then it never starts. The following message appears when I use the command "sudo /usr/local/bin/paperpi -d":

Traceback (most recent call last):
File "/usr/local/paperpi/paperpi.py", line 32, in
import ArgConfigParse
ModuleNotFoundError: No module named 'ArgConfigParse'

Tried to install the modul with pip install ArgConfigParse, says installed and I see it with the command "pip list".

ArgConfigParse 0.2.7 /home/pi/.local/lib/python3.11/site-packages pip

Any idea?

Thanks

It sounds like the virtual environment is failing to load for some reason. You've probably installed ArgConfigParse in your system python env. I need a little more info to diagnose the problem.

Can you supply the following information?

Hardware

• Full EPD version: paste here
• Pi Version (use cat /proc/device-tree/model): paste here

OS Info
Run cat /etc/os-release

paste here

[main] Section of Config
Copy and paste the [main] section of your config file

• Daemon mode (start at boot) use: /etc/default/paperpi.ini
• Single user mode (start manually) use: ~/.config/com.txoof.paperpi/paperpi.ini

paste here

Then try these steps and paste in the results

1. Run /usr/local/bin/paperpi -V:
2. run cd /usr/local/paperpi; source /usr/local/paperpi/venv_paperpi/bin/activate
3. run pip list and paste in the results below
4. and finally ls -alh /usr/local/paperpi

Thanks for the info.

Something is still really off are you sure you ran cd /usr/local/paperpi; source /usr/local/paperpi/venv_paperpi/bin/activate; pip list? It looks to me like you didn't launch the project venv before running pip.

If you're sure you did that and only got "setuptools", then something went horribly wrong with the install. There should be a huge list of things that were installed in the venv.

The best option is to run the installer again. If you get similarly bad results with the installer, you can try this manual uninstall/install:

DO THIS WITH CAUTION!

Remove the old paperpi

1. sudo rm /usr/local/bin/paperpi
2. sudo rm -rf /usr/local/paperpi

Manual Install PaperPi

1. apt install git
2. cd ~/
3. git clone https://github.com/txoof/PaperPi.git
4. cd PaperPi
5. sudo ./install/install.sh

If you see any errors, those would be super helpful for debugging the installer process.

In the future, if you paste content from the terminal/log files/whatever, can you try using MarkDown code fences? You can surround your pasted errors with three back tick characters "```" before and after the pasted content.

Code fences turns this:

Hi, thank you for your respons.

Yes, I think I should be in the project venv:

@daavid1995 Sorry I missed this. I've been on the road. I'll try to take a look over the weekend.

[AaronCiuffo245484]

The IT8951 error is pretty clearly a problem and looks like it might be causing the entire install to bail out. You don't need the module that's failing, so there should be a work around. I'll see if I can find some time this weekend to fix this.
