finnhub installation using pip

I've currently installation of python 3.10 [not conda dist]. I'm trying to import finnhub using both cmd but I'm confronted with the following error message:
C:\Users\Admin>python -m pip install finnhub
ERROR: Could not find a version that satisfies the requirement finnhub (from versions: none)
ERROR: No matching distribution found for finnhub
Any ideas on what I'm missing please? I've also tried to install this package using PyCharm but this results in the following error:
C:\Users\Admin\PycharmProjects\NewPython\venv\Scripts\python.exe C:/Users/Admin/PycharmProjects/NewPython/main.py
Traceback (most recent call last):
File "C:\Users\Admin\PycharmProjects\NewPython\main.py", line 1, in <module>
import finnhub
ModuleNotFoundError: No module named 'finnhub'
Process finished with exit code 1
I have added the python installation to PATH and the current version of pip is the latest version.
Many thanks in advance for your help.
Question update
In the meantime, I have spotted an old environment reference which has been now removed. This seems to allow the install of finnhub using
pip install finnhub--python
but not
pip install finnhub
Code below:
C:\Users\Admin>pip install finnhub
ERROR: Could not find a version that satisfies the requirement finnhub (from versions: none)
ERROR: No matching distribution found for finnhub
C:\Users\Admin>pip install finnhub--python

C:\Users\Admin>
When using PyCharm to try to access this from the IDE, I am now confronted with:
C:\Users\Admin\PycharmProjects\pythonProject2\venv\Scripts\python.exe C:/Users/Admin/PycharmProjects/pythonProject2/main.py
Traceback (most recent call last):
File "C:\Users\Admin\PycharmProjects\pythonProject2\main.py", line 1, in <module>
import finnhub
ModuleNotFoundError: No module named 'finnhub'
Process finished with exit code 1

From the the section "Installation" of the package's documentation:
pip install finnhub-python

In this command, it becomes clear that you have installed finhub globally,
C:\Users\Admin>pip install finnhub--python
Requirement already satisfied: finnhub--python in c:\users\admin\appdata\local\programs\python\python310\lib\site-packages (2.4.13)
But when running your script your command looks like this
C:\Users\Admin\PycharmProjects\NewPython\venv\Scripts\python.exe C:/Users/Admin/PycharmProjects/NewPython/main.py
So you are using a virtual environment for your project in which finnhub is probably not installed yet.
Try:
C:\Users\Admin\PycharmProjects\NewPython\venv\Scripts\python.exe -m pip install finnhub-python
Alternatively, you can use pycharm as well
With your project open go to File
Select Settings->Project->Python Interpreter
You should see a list of packages and their version. Hit the little + button above it
Search for finnhub-python, select it and hit Install Package

ImportError: No module named request, but in Path

request and requests are not the same thing.
urllib.request is not the same as either.
Just because two things have kind of similar names doesn’t mean they’re interchangeable. requests is a third-party package for doing HTTP at a high level. urllib.request is a module in the urllib package in the Python 3 standard library for doing HTTP, FTP, and other protocols at a lower level.
The problem here is that you’re trying to run Python 3 code that uses urllib.request, in Python 2.7. You can rename every reference to urllib.request to its rough Python 2 equivalent, urllib2, and that might work. But it might not. And there’s a good chance that the code has other Python 3-specific imports or features, so it still won’t run, or won’t run correctly.
The right thing to do is to run the Python 3 code in Python 3.
If you can’t do this, you need to look into porting the code back to Python 2, or to dual-version code using six or modernize. The 3to2 tool can help get you started, but it won’t do everything for you automatically, and it’s not something people can tell you how to do in a simple Stack Overflow answer.

Could not satisfy Django application requirements

I have been trying to run a Django application since afternoon. The application probably uses Python 2.7. I have created virtual environment and I have installed Django with Python PIP package manager. However, this application requires JQuery package for proper working. Unfortunately, an error has occurred when I tried to install JQuery package with PIP:

How can I satisfy these dependencies?

Your project almost certainly doesn't rely on the python package jQuery, since it appears to be for turbogears, which is a completely different web framework to Django.
If your templates require jQuery then you should download and add it to your static files, or use a CDN.

pip Installing a python module in Python 3, but that module has a dependency package that requires Python 2

so I am new to Python and what is a good way to learn it is to do some personal project :) So I am on my Windows and using virtualenv to contain environment
So, I need to use the Scrappy module:
pip install scrappy
Collecting scrappy

Collecting guessit (from scrappy)

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\USERPH\AppData\Local\Temp\pip-build-__zp7zbj\h

Its because hachoir-metadata is a Python2 dependent package, so I tried installing their Python 3 version
pip install hachoir3
I confirmed that it was installed using
pip list | Select-String hachoir3
so I tried running
pip install scrappy again
but same error.
Any work around to install scrappy? I cannot go down to Python 2.
Thanks!

Scrappy itself contains code that only works in Python 2. I.e. Scrappy cannot be used with Python 3+.

Unable to resolve dependencies for the Python OCR Library pypdfocr [duplicate]

How can I rectify this installation problem with pypdfocr library?

Use Python 2.x instead of 3.x or find the line where syntax error occurs and add the parenthesis.
See, in Python 3 exec is a function, but in Python 2 exec is a command.
So in Python 3, you have to put arguments into parenthesis to make a call to exec() properly.
So, you're trying to install the package to Python3 that is meant for Python 2.
At least installation script is.
OK, that is what I can deduce from that error log. I am not familiar with PyPDFOCR, although I Suspect it uses tesseract for OCRing, and probably PDFMiner to access images from a PDF document.
To continue using PIP, first download, not install, the package, then change setup.py, then do python setup.py install.
Although, if a script is for Python 2, it may be that the package in question is meant only for Python 2. Because pip should automatically choose the correct package version for installed Python.
All the mess may have something to do with the Anaconda distro.
Good luck.
