Unable to install mysqlclient on ubuntu using pip

I have a following problem. I would like to install MySQLdb. I try pip install mysqlclient but I got this error message:

I am using Python 3.8 on Ubuntu. How can I fix it, please?

Please read and follow the installation instructions for Linux.
For Ubuntu,
sudo apt-get install python3-dev default-libmysqlclient-dev build-essential
to install the required libraries before attempting to
pip install mysqlclient

Even after I install psycopg2 with pip, I still get No matching distribution found for psycopg2

I've been working on this over a week now, and the version problems just seem endless. I've downloaded a complex Django app, which has multiple install scripts. It is very complex.
I got an error that needed to be fixed by deleting Pipfile.lock, then I got some "missing module" errors and I manually did:
pip3 install importlib_metadata
pip3 install ConfigParser
but now I try:
pipenv lock
I get absolutely endless error messages, a small part of which looks like:

ERROR: No matching distribution found for psycopg2
but the heart of it seems to be:
ERROR: No matching distribution found for psycopg2
I'm trying to figure out how to install this, but I'm also curious if anyone has some meta level comment that might help resolve all of these errors.
I should add, I can do this:
pip3 install psycopg2-binary
which succeeds, but then when I do this:
pipenv lock
I still get:
ERROR: No matching distribution found for psycopg2
I also see this line:
"Defaulting to user installation because normal site-packages is not writeable"
If I knew where the normal site-packages was, I would make it writeable, but I have no idea.
If I try:
pip3 install psycopg2
I get:

I cannot afford to spend another week on this. I wonder if there is some way to break through and get everything working. Is there truly no way to get Python to do more of the work of figuring out what dependencies need to be installed?

Error while installing flask-mysqldb on ubuntu 20.04

I am building a flask project and I want to use MySQL database. I need flask-mysqldb as an ORM for that. So as a good practice, I created a virtual environment, install flask and other dependencies, and then for installing flask-mysqldb, I used pip install flask-mysqldb. This suddenly gives me bunch of errors. At first I realized, I dont have MySQL installed on my system. So even after installing it these errors won't go away. I also tried pip install Flask-MySQLdb don't know how this is different from the first command but same errors.
I tried searching for errors online regarding flask-mysqldb, but most of them relate to some mysql.h file error which doesn't show in my terminal logs.

you should reinstall cython (pip install cython).

Any tips would be LOVELY!

I’ve also had similar experience with M1. I think it’s due to the mysql config. So first of all locate where your mysql_config is ( it can either be in /opt or /bin directories). For instance mine is in:
/opt/homebrew/bin
Once you’ve found the file, you need to edit the file with your favorite editor (I use nano) and change this line in the configuration:
# Create options
libs="-L$pkglibdir"
libs="$libs -l "
change it to this:
# Create options
libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"
after editing install mysqlclient again. You can also ensure that gcc is already installed on your Mac
