AttributeError: 'PosixPath' object has no attribute 'read_text' while building heroku app

I am getting AttributeError: 'PosixPath' object has no attribute 'read_text' when trying to deploy a django app to heroku. The problem occurs when pip is installing pathlib python library after running the git push heroku main command on the command line. Is there something I am doing wrong?
The following is the log generated on heroku, which is similar to what I saw on the command line:

I found a solution that worked for me; I removed the packages mega and pathlib form the requirements.txt file.

Install of PySuperTuxKartData getting stuck

I am trying to install PySuperTuxKart onto my windows 10 computer via anaconda.
However every time I try to install PySuperTuxKart, PySuperTuxKart installs fine but PySuperTuxKartData seems to hang. I have let it sit for 5 minutes with no progress being made. My metric is that the loading animation just gets stuck this whole time and does not move. I have tried this on python versions 3.9-3.7. It installs fine in a venv that is version 3.10 but I need a package that is only available up to python 3.9. I enabled the verbose flag on the pip install and this is the output.

Successful build of Heroku Python App but execution is unsuccessful and open app throws error

I recently successfully deployed a Heroku app(view log below for details), but when I try to access my app through a browser, it returns with An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command heroku logs --tail. Furthermore, my app was for a Discord.Py bot, and the bot was not online like it should be.

https://app.herokuapp.com/ deployed to Heroku

Your application is a worker (Procfile declares types -> worker) so it does respond to HTTP requests.
Change to web and make sure you bind the PORT provided by Heroku.
BTW BOTs can run as workers (without dealing with incoming requests) if they poll the server for messages/updates. This is a viable option too (keep it as worker) but ensure the BOT logs what it does at startup.

Can I run Python app using WMI in GitLab CI if using Linux Docker image?

Objective
In Gitlab runner, run:
some JMeter tests
a Python application that uses WMI to collect server metrics
Problem
The JMeter commands worked fine, using the alpine/jmeter image.
default:
image:
name: alpine/jmeter:5.4.1
entrypoint: [""]
No problem there.
But I want to run a Python program I wrote that uses WMI to get Windows performance counters.
Problem: when doing pip install -r requirements.txt, everything gets installed, but that last part fails:
$ pip install -r ../../requirements.txt

What I've Tried
replace pywin32==301 with pypywin32
ensured that python version is 3.8
Tried using python:3.8-windowsservercore, but that doesn't even get off the ground because it conflicts with the default JMeter image which is Linux.
I tried adding pywin32==300 to requirements.txt.
The result then is just

Am I trying to do something impossible?
Any idea how I can get the Python application to run?

No, the wmi package relies on pywin32 which is only possible to use on Windows because it relies on Windows binary files (windows DLL files) which can only be run on Windows.
Therefore, you must run this Python app on Windows, not Linux.
Jmeter, however, does work on both Windows and Linux.

Warning: Your slug size (305 MB) exceeds our soft limit (300 MB) which may affect boot time.
Your app must boot within the time limit or it'll be killed
Using the release phase in the Procfile works, but the release phase isn't part of the build, meaning that the makemigrations command creates the files in an ephemeral file system, meaning your next push will create brand new migrations again, which can cause issues with the database.
Finally, if your app is serving any sort of static files, and is used in production, then the DEBUG setting being False will mean you'll have to run collectstatic (again, as part of the build and not release).
