ERROR: Failed building wheel for pqcrypto

I am trying to install python packages in the requirements.txt and get this fatal error.
note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for pqcrypto

ERROR: Command errored out with exit status 1: While deploying codes on Heroku

I am trying to deploy my flask application on the Heroku platform. I am completely new to this platform. I have made my requirements.txt using the command pip freeze > requirements.txt also created a Procfile that contain web: gunicorn app:app
When I am trying to deploy the code on Heroku the same error is showing (Preparing wheel metadata: finished with status 'error') I have gone through the error message and as per the instruction I tried to install the rust package manager through the given link https://rustup.rs/ but still the same error is showing.
Please help me to figure out what I am missing here.
Thanks in advance

Heroku Dash app failing to deploy but successfully builds

Hi I'm building a Dash app using the Python framework and my build logs are suggesting the app was built successfully. In fact when I go to the Heroku website it shows build successful under the build logs. However, when I view the Heroku URL it says application error. Below are the build logs, any help is appreciated. I've also tried restarting the app as Heroku documentation suggests certain errors can only be captures via the restart method but still no errors have appeared in the logs.

Uncomplete installation of the RASA package with the issue: FileNotFoundError: [Errno 2] No such file or directory: 'HISTORY.rst'

i have been using rasa for the past few weeks without problems. But recently i had issues with the installation of Spacy, leading me to uninstall an reinstall python. The issue may have occurred because of some dualities between python3.8 and 3.9 which i wasnt abled to pinpoint.
After deleting all python version from my computer, i just reinstalled python 3.9.2. and reinstall rasa with:
pip3 install rasa
this gave me the next output:

Successfully installed rasa-0.0.5
the result is that rasa is install in version 0.0.5 when it should be in version 2.4.
i have no clue why an error occurred at the end as it did not happen the first i downloaded it a few weeks ago.
What should i do to resolve this issue?
Thanks for your time.

rasa 2.4 declares compatibility with Python 3.6, 3.7 and 3.8 but not 3.9 so pip is trying to find one compatible with 3.9 or at least one that doesn't declare any restriction. It finds such release at version 0.0.5.
To use rasa 2.4 downgrade to Python 3.8.
PS. Don't hurry up to upgrade to the latest Python — 3rd-party packages are usually not so fast. Currently Python 3.7 and 3.8 are the best.

What is missing in Python Flask app that build is failing?

what could be the build failure reason? I tried different versions of MarkupSafe but still its getting failed. Tried running different branches too, all builds are getting failed.
Does it has any version issues? Are there any other libraries required? Using postgres for db.
