Why does this happens when downgrading the library
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
pyppeteer 0.2.5 requires importlib-metadata<3.0.0,>=2.1.1; python_version < "3.8", but you have importlib-metadata 4.12.0 which is incompatible.
pyppeteer 0.2.5 requires urllib3<2.0.0,>=1.25.8, but you have urllib3 1.24.3 which is incompatible.

WARNING: You are using pip version 22.0.4; however, version 22.2.2 is available.
You should consider upgrading via the '/Users/admin/.local/share/virtualenvs/scrapers-XJakbnzz/bin/python -m pip install --upgrade pip' command.

This is a conflict of package versions. To fix it, you'll need to follow these steps:
1)pip list
2)copy all of your packages
3)create a new file called requirements.txt
4)put all of your packages in there (without versions). The file should look like this:
autopep8
certifi
chardet
charset-normalizer
click
colorama
discord
Flask
itsdangerous
pip
praw
(except this has to be a list of your packages that you got while running pip list)
5)pip install -r requirements.txt
This will tell pip to solve the version conflict.

pip install PyGObject --ignore-installed

Django failed to build wheel for python-ldap

I'm new to Python Django, I have integrated my Django application on Windows 7 machine. When I tried to integrate LDAP by using pip install django-auth-ldap but unfortunately I got an error
Failed building wheel for python-ldap
Running setup.py clean for python-ldap
Failed to build python-ldap
django-python3-ldap 0.11.1 has requirement pyasn1==0.3.2, but you'll have pyasn1 0.4.4 which is incompatible.
Please help me to escape me from this issue, bcz I have been struck here for a couple of days

I think this message is pretty clear:
django-python3-ldap 0.11.1 has requirement pyasn1==0.3.2, but you'll have pyasn1 0.4.4 which is incompatible.
When using django-python3-ldap you have to explicitly use version 0.3.2 of module pyasn1. But something else already installed a newer version of pyasn1 to you build environment.
So you have to specify version pinning information in install_requires or requirements files.

Try Updating pip using
python -m pip install -U pip
or
pip install --upgrade pip

Downgrading Python Setuptools

I am getting an error while attempting to use Pyinstaller. After doing some research I believe the error is caused by a bug in the most recent version of setuptools (19.3). The fix seems to be downgrading to setuptools version 19.2. My issue is with the downgrade itself. My question is how does one downgrade setuptools in Ubuntu 15.04?

Just specify the version using pip:
pip install setuptools==19.2
If you are installing globally you will obviously need sudo.
~$ sudo pip install setuptools==19.2
