i am using:
Python 3.10.1
Pip 21.2.4
Python Project in an virtual enviroment
My Problem:
Everytime i try to install any package (for instance opencv) i get the following error:

I tried some of the trusted hosts hints i found but nothing worked.
my be somebody knows where my problem come from?
This issue is related to SSL Certificate. Try pasting this in CMD:
python -m pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --upgrade pip
If that doesn't do the work, try this:
pip install requests==2.18.4 --user --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org
If you have installed Fiddler earlier, uninstall it, that might be the cause of the problem.
And lastly if none of this works, then you need to directly download the files from wheel. This means that first you'll download the package on your PC, then write pip install your-package.whl.
You can find OpenCV and other package's .whl files online easily.

Try this
pip3 install virtualenv
After that
virtualenv venv
Then activate your environment
source venv/bin/activate
And now you can install Django, I think this is better way and safe, rather than install django in a global system.
pip install django

I'm new to PyCharm and wanted to install pandas in my project.
So, I used the following commands(one by one because the first one didn't work) in the terminal of PyCharm to do it.
>pip install pandas
>python -m pip install pandas
I got the same errors for both of them.
ERROR :

How do I install pandas now? Please help.

So, my system has Anaconda installed and while creating the project, I forgot to the change the 'basic interpreter' from Conda to normal python.exe, that's why I wasn't able to install anything in it as I was using Anaconda's pip.
I'm trying to use virtualenv on my Mac (El Capitan) but something must have changed recently, as it's no longer working, and complains about SSL problems.
It's the first time I've had to use this project in about 9 months, and in that time, I've not changed anything on my system regarding Python.
In an effort to get it working, over the past day or so I've uninstalled virtualenv, manually deleted some files (I found these instructions in a GitHub issue, but I can't find them again to provide a link, but if I remember correctly, it was just deleting broken symlinks and directories relating to virtualenv,) and then uninstalled Python via Brew, leaving me with a system that had no Python, pip, or virtualenv libraries or executables on it.
Then I ran brew install python2 to get Python installed. Then I ran pip install virtualenv which gave me the same SSL error as before. I manually downloaded virtualenv from the URL pip was trying to download it from, and then pip installed it locally using the downloaded file. This worked. However, when I then run virtualenv venv, I still get the same SSL error.
I've seen issues offering all kinds of advice, from downloading DigiCertHighAssuranceEVRootCA.pem and using it via the --cert option, creating a pip.ini file with trusted-host=files.pythonhosted.org in it, using the --trusted-host option, using a different network that isn't my company's corporate network, but none of it so far has worked for me.
I am consistently getting the following SSL error whenever I try to pip install anything, or, in this specific example, create a new virtualenv:

Is there some other way I can get this to work? This project cannot be deployed (using an Ansible role called ansistrano) because of this error.
EDIT:
I just tried uninstalling/removing Virtualenv, Pip and Python again, reinstalling Python, then manually installing pip with https://bootstrap.pypa.io/get-pip.py, which gives:

So it turns out that this is because the company I work for use Cisco's Umbrella DNS security system, that inserts itself in all DNS requests. This breaks SSL in Python, apparently, even though I can successfully manually download the file with curl.
By adding
151.101.1.63 files.pythonhosted.org
to my hosts file, I was able to get a system that behaved exactly as expected. Hope this helps others in the future who also are forced to go through Umbrella.
