Cannot install psycopg2 with pip3 on M1 Mac

I cannot install psycopg2 on my M1 Mac and I used pip3.
When I tried to install with pip3 install psycopg2 The output like that:

Its beginning of the error, After that its tried to install each previous version of Psycopg
==============================================================================
Also, I tried to install with source code with :
git clone https://github.com/psycopg/psycopg2.git
cd psycopg2
python3 setup.py build
Its return as error like that:
running build
running build_py
running build_ext

Also
python3 setup.py build
return the same error as python3 setup.py build
How can I install it?

try this:
brew install libpq --build-from-source
brew install openssl
export LDFLAGS="-L/opt/homebrew/opt/openssl#1.1/lib -L/opt/homebrew/opt/libpq/lib"
export CPPFLAGS="-I/opt/homebrew/opt/openssl#1.1/include -I/opt/homebrew/opt/libpq/include"
pip3 install psycopg2

Before reverting to any of the older answers, I would recommend trying the following:
Install Postgres using brew install postgres, then pip3 install psycopg2.
Worked on Mac M1, Monterey, Python 3.9.
Thanks to Kori Vernon.

Thanks to active development, now there is a new release of psycopg2 as well as psycopg2-binary which is compatible with M1 devices.
Ver. 2.9.1 works smooth. Tried and tested
Reference - https://github.com/psycopg/psycopg2/issues/1200

Following this steps solved my problem:
❯ brew install postgresql#14
# If you open a new terminal tab you will see that pg_config is available
❯ export CPPFLAGS="-I/opt/homebrew/opt/openssl#1.1/include"
❯ export LDFLAGS="-L/opt/homebrew/opt/openssl#1.1/lib -L${HOME}/.pyenv/versions/3.10.7/lib" # use your current python version
❯ python -V
Python 3.10.7 # make sure it matches the same above configuration
❯ pip install psycopg2-binary==2.8.5

python setuptools editable install with parallel build

I know there are a few questions on here and around the internet regarding parallel python builds using setuptools. Yet, none provide a solution. It's also worth mentioning that most I come across are 5+ years old.
It seems that I can achieve my desired parallelization during install through:
>> python setup.py build -j 4
>> python setup.py install
But this doesn't work for editable installations, i.e. for development. The editable install requires calling python setup.py develop instead of the above 2 commands. However, there is no -j flag for develop. If I try to call it after the build, for example,
>> python setup.py build -j 4
>> python setup.py develop
I get the error:

Additionally, it is recommended to use pip install -e . --user instead of python setup.py develop anyway. If I try to call that after the parallel build, I get:
>> python setup.py build -j 4
>> pip install -e . --user

Does anyone know of a good way to get the parallelized build in an editable install? Ideally, it would be though the pip install -e ... formulations, but really anything would be better than nothing.

Cannot run bdist_wheel build command on my setup.py

I have created a pypi package for educational purposes, and I wanted to do an upgrade. I did through the usual steps(do the changes, run setup.py etc)
but when I do:
python3 setup.py bdist_wheel
I am getting the error
python3 setup.py build bdist_wheel
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: setup.py --help [cmd1 cmd2 ...]
or: setup.py --help-commands
or: setup.py cmd --help
error: invalid command 'bdist_wheel'
Wheel and pip are installed and up to date:
pip3 install wheel
Requirement already satisfied: wheel in /usr/local/lib/python3.4/dist-
packages (0.31.0)
The help of the command, does not seem to support bdist_wheel.
Am I missing something?
python3 setup.py --help-commands
Standard commands:
build build everything needed to install
build_py "build" pure Python modules (copy to build directory)
build_ext build C/C++ extensions (compile/link to build directory)
build_clib build C/C++ libraries used by Python extensions
build_scripts "build" scripts (copy and fixup #! line)
clean clean up temporary files from 'build' command
install install everything from build directory
install_lib install all Python modules (extensions and pure Python)
install_headers install C/C++ header files
install_scripts install scripts (Python or otherwise)
install_data install data files

saveopts save supplied options to setup.cfg or other config file
setopt set an option in setup.cfg or another config file
test run unit tests after in-place build
upload_docs Upload documentation to PyPI
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: setup.py --help [cmd1 cmd2 ...]
or: setup.py --help-commands
or: setup.py cmd --help
EDIT:
python3 --version
Python 3.6.3
pip3 --version
pip 10.0.1 from /usr/local/lib/python3.4/dist-packages/pip (python 3.4)

Looks like pip version and python version didnt match...fixing this removed the problem.
