Issues in installing pygobject in MacOS

I am trying to install pygobject using pip, even with brew in MacOS, but now successful. I followed guides.
If I use the official installation guide in https://pygobject.readthedocs.io/en/latest/getting_started.html, then I have gtk+3 installed, but when I try to import the library:
python3 -c 'import gi; gi.require_version("Gtk", "3.0"); print("ok")'
Traceback (most recent call last):
File "<string>", line 1, in <module>
This is the output of the installation after using pip3:

ERROR: Failed building wheel for pygobject
Failed to build pygobject
ERROR: Could not build wheels for pygobject, which is required to install pyproject.toml-based projects
(base) khalil presentation (master) >> ```

Problem solved! Thanks to #rasjani
First, I upgraded to the latest version of python, then I create a new_env using conda:
conda create --name new_env python=3.9.12
conda activate new_env
conda install -c conda-forge pygobject
Solution from: Github

ERROR: Failed building wheel for sip
Failed to build sip
ERROR: Could not build wheels for sip, which is required to install pyproject.toml-based projects
Can you please help me find the problem.
I wrote this ( line copied from https://pypi.org/project/sip/ ) :
pip install sip
OS : Microsoft Windows 8.1 Pro [Version 6.3.9600]
Python Version: 3.10.0
PIP Version: 21.3.1

I just tried installing sip in a venv, and it went smoothly. I guess you need to upgrade pip:
pip install --upgrade pip
and then run again the installation script:
pip install sip

Run the command in the script directory on this path C:\Users\XXXXX\AppData\Local\Programs\Python\Python310\Scripts
I founded that method on this video:
https://www.youtube.com/watch?v=YVfvLYM2Yes&ab_channel=MustufaBaig
This method worked for me.

ImportError: No module named numpy.distutils.core
However, when I import the package in python, it works without any issue.
import numpy.distutils.core as np

The issue occured because I had two python versions (v 2.7.13) and Enthought Canopy (Python 2.7.11). As Python 2.7.11 already had Numpy package, xgboost got installed successfully.
python setup.py install

For me in a Docker, installing numpy first worked:

Does anyone have an idea about my case? thanks in advance

There is the huge list of Unofficial Windows Binaries for Python Extension Packages which are extremely useful for Windows users.
http://www.lfd.uci.edu/~gohlke/pythonlibs/#psycopg
Go to the link, download and install it and you are good to go.
Cheers !

Don't try to compile psycopg2 for Windows. You'll need a Visual Studio install or Windows SDK and all sorts of other mess.
Just grab a binary build: http://initd.org/psycopg/download/
