python3.10 bdist_wheel did not run successfully when install cffi

i installed Ubuntu 22.04 (fresh installation) an create an virtualenv with Python 3.10.
The installed packages are as follows:
libpython3.10:amd64
libpython3.10-dbg:amd64
libpython3.10-dev:amd64
libpython3.10-minimal:amd64
libpython3.10-stdlib:amd64
python3.10
python3.10-dbg
python3.10-dev
python3.10-minimal
python3.10-venv
When I try to install the application requirements file I see this error:

any ideas??
I have tried reinstalling the Python installation packages but the problem persists, I have read some publications and indicate that the problem may be caused because there are no headers related to the python dev package.

Most probably cffi==1.14.0 is not compatible with Python 3.10. Try the latest version:
pip install cffi==1.15.1

lxml: error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

I've seen some posts on lxml installing problems, but none of the answers I found was of any help. Many said to install python-dev, libxml2 and libxslt to solve the problem. They are already installed, but I still get the following outcome (keep in mind that I'm installing everything locally using virtualenv):

What does warning: no previously-included files found matching '*.py' mean?
/usr/bin/ld: cannot find -lz what is -lz? How to install it?

The relevant error is this:
/usr/bin/ld: cannot find -lz
...which indicates that the linker couldn't find libz.so, which means you don't have zlib installed in a location in your library search path.
Install zlib; the method for doing so depends on your operating system, so there's no generic answer. It might be something like:
sudo apt-get install zlib-dev # on a Debian derivative
sudo apt-get install zlib1g-dev # on Ubuntu 14.04 (see below)
sudo yum install zlib-devel # on a Red Hat derivative
sudo port install zlib # on a ports-based system
sudo pacman -S zlib # on Arch Linux
or any number of other things as appropriate.
Assuming you want to find the appropriate package name for a given version of Ubuntu, one can search for the package containing libz.so on packages.ubuntu.com; the linked results are for Trusty.

Django MySQLClient pip compile failure on Linux

Django documentation as of v1.8 recommends using mysqlclient connector for the framework. I'm attempting to pip install the package on Ubuntu 14.04 with Python 3.4 and running into a GCC error that I'm unable to find reference to. I'm not an expert on compiling software, so was hoping somebody can see the solution.
I believe I'm getting a linking error. I have installed distro specific mysql headers, but it looked like they were only applicable to Python 2.7.x.
Not sure how much of this is useful so apologies for the long paste, but here's the error log:

It looks like you're missing zlib; you'll want to install it: apt-get install zlib1g-dev
I also suggest reading over the README and confirming you have all other dependencies met: https://github.com/dccmx/mysqldb/blob/master/README
Also, I suggest using mysqlclient over MySQLdb as its a fork of MySQLdb and what Django recommends.

using this MySQL Connector worked for me:
https://dev.mysql.com/downloads/connector/python/
https://dev.mysql.com/doc/connector-python/en/connector-python-installation.html

Improperly configured: Usage of the xml aspects requires lxml and defusedxml

I'm trying to use XML for a Django website I'm making but I ran into the following error when I set the page to display xml:
ImproperlyConfigured at /articles/api/article/
Usage of the XML aspects requires lxml and defusedxml.
The page was working the way I wanted it to when I set it to display json. And I thought I installed lxml and defusedxml when I used the command
pip install defusedxml "lxml>=3"
But I got this log on the command line. It was installing fine until some errors popped up:

I looked at similar posts about errors when installing lxml but these posts didn't have the same error messages as mine. I looked at the lxml documentation and tried to install it according to the documentation, but I still cannot get lxml or defusedxml installed.
I don't know what I'm installing incorrectly or what to do. But I appreciate any help that you can give me. Thank you.

The error "/usr/bin/ld: cannot find -lz": that means you don't have zlib-dev or zlib1g-dev in installed depending on your linux distribution, try install first this library.

ImportError: No module named lxml.html when creating scrapy project

I'm on OS 10.9.5 and get the following error when I try to create a scrapy project:

I first tried to uninstall and then reinstall scrapy using pip. I'm not sure whether the problem is actually that something went wrong during the installation of scrapy. I get the following output when installing scrapy:

Can anybody please help?

The problem was this part:
You have not agreed to the Xcode license agreements, please run 'xcodebuild -license' (for user-level acceptance) or 'sudo xcodebuild -license' (for system-wide acceptance) from within a Terminal window to review and agree to the Xcode license agreements.
Running sudo xcodebuild -license and reinstalling scrapy solved the problem.
