MMM-PythonPrint customisation

[sdetweil]

@karsten13 and I missed the latest/fat under the TAG column of your table… tldr(lol), my apologies

[RobCee]

@sdetweil I have started fresh and am still having the same issue.
New install of buster, fully updated.
Installed all the MM and node successfully.
MM runs as expected.
Checked that python and python3 are both available to the OS.
Added the MMM-PythonPrint to the modules dir.

This is my config section:

		{
			module:"MMM-PythonPrint",
			position:"center",
			disabled:false,
			config: {
				// name of the python process to execute (could be python3)
				pythonName: 'python',
				// command file in module folder
				// if false, YOU will provide the full path to the python program
				localfolder: true,

				// spawn a python pgm that writes over and over (timed maybe), but keeps running
				command: 'printit.py',
				repetative: true,

				// spawn a one time output  script, but relaunch it every cycletime milliseconds

				// repretative: false,
				// command: 'printitonce.py',
				cycletime: 2000,

				// print debugging messages from the node_helper
				debug: true
			}
		 },

@RobCee weird, sorry, typo… fixed

git pull to get the update

[RobCee]

@sdetweil I found another, just up from that one - you have a missing ‘t’ in this line

this.config.command=this.config.command.slice(his.config.pythonName.length)

[sdetweil]

@RobCee fixed… bad day at the finger farm…yikes sorry

[RobCee]

But even with that _ removed, I am still getting an odd error:

 TypeError: this.file is not a function

[sdetweil]

@RobCee ok, fixed, tested… sorry again
git pull

[RobCee]

@sdetweil - apologies not necessary - I am just happy you are able to look at it.

Hurrah! It works!

i have also the MM os and i try to make it work
I have added - /usr/bin/python3:/usr/bin/python3 to the docker compose
and now i have the error

[15.07.2022 14:23.42.599] [LOG]   MMM-PythonPrint received a socket notification: CONFIG - Payload: [object Object]

Current thread 0x76fb37a0 (most recent call first):

a played around with adding $PYTHONHOME to env but without any result
does anyone know a work around to find the libraries?

@diemen112 I think this answers
https://askubuntu.com/questions/905372/could-not-find-platform-independent-libraries-prefix

running under docker is a fun experience?

did u install python as part of the container startup?
