Pip hangs on installing packages

I'm using django in a virtual environment. I'm using powershell and trying to install pyopenssl.
Inside Virtual environment:
pip version = 19.2.3
python version = 3.8.3
Outside Virtual environment:
pip version = 21.2.4
python version = 3.8.3
I tried to upgrade pip inside virtual environment using python -m pip install -U pip and pip install --upgrade pip but it is hanged without producing any output here is the screenshot.
I try pip install pyopenssl:

Here again i'm stuck at this output, and pyOpenSSL is not installed.
However, pip install pyopenssl worked outside of the virtual environment screenshot
I'm stuck at this freeze for 2 days.
If you know the solution then please answer it. Thankyou

Here's what worked for me
Step 1: First I uninstalled pip:
pip uninstall pip
To make sure pip is uninstalled type pip and make sure you get ModuleNotFoundError: No module named 'pip'
Step 2: Download PIP get-pip.py:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
Step 3: Install PIP:
python get-pip.py
To make sure pip is installed run pip --version make sure it is latest, (21.2.4) as of now.
Finally I was able to install pyopenssl :))
pip install pyopenssl

Error while trying to install pyttsx3 library

I was trying to install pyttsx3 using pip on windows 10 when I get this error plus a very fat red code that I included
Collecting comtypes; platform_system == "Windows"
Using cached comtypes-1.1.7.zip (180 kB)
Using legacy setup.py install for comtypes, since package 'wheel' is not installed.
Installing collected packages: comtypes, pyttsx3
Running setup.py install for comtypes ... error```
[1]: https://i.stack.imgur.com/xRdBx.png

Try updating setup tools and then try again the install:
pip install -U setuptools
pip install pyttsx3
If it doesn't solve your issue you can also try to specify the version for pyttsx3
pip install -U pyttsx3==2.71
If this doesn't work also, try installing it directly from the official github repo:
pip install git+https://github.com/nateshmbhat/pyttsx3
If still doesn't work, consider changing your python version.

I think this will solve your issue
pip install wheel
and then,
pip install pyttsx3

pip doesn't install anything and tells me to upgrade pip

So whenever I try to install anything pip throws this error:
DEVICE_NAME:~ MY_NAME$ sudo pip install pyautogui

You are using pip version 10.0.0b2, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
and when I then type pip install --upgrade pip it throws the same error. I've tried reinstalling pip thrice over already and I'm completely out of ideas as to what I can do.
It also does this when I try to install any other package, not jus pyautogui.
Please note that this is only on my OSX machine whilst on my PC it works perfectly fine.

There is always the option downloading a .whl-file and install it with
pip install /some-dir/some-file.whl
I have the same problems as you have with Py 3.4, so i just use Py 3.5. But I know there is no Version of PyAutoGui for 3.x. You can install this package per wheel, and if it is only this package, this'd be ok... Obviously, it does do Pillow...

PIP and python -m pip doesnt work when I specify the version

I have got a problem when I want to install a specific version of a python library since I updated pip to 10.0.0. I would like to install it back but I cant find it, so I am forced to use the whole command , but it doesnt let me to install specific version of python package, any idea how to do it ?

also this is the part of a pip error I am dealing with , so any help would be awesome ^.^ ( Tried few things from stack overflow but neighter of them worked )
C:\Windows\system32>pip install APScheduler==3.0.0
Fatal error in launcher: Unable to create process using '""c:\program files (x86)\python36-32\python.exe" "C:\Program Files (x86)\Python36-32\Scripts\pip.exe" install APScheduler==3.0.0'

Try using the --upgrade flag.
python -m pip install --upgrade APScheduler==3.0.0
It should work for downgrades as well

Make sure that both python.exe and pip are available in the locations in which it is looking for them. The pip launcher program is failing to run the command that it's printing in the error, which is probably because it can't find the relevant files.
Alternatively, just run pip using python -m pip which seems to work fine.

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
