Issues installing pywin32

pip install pywin32
When I try the above code, I get the following error in Jupyter Notebook.
ERROR: Could not find a version that satisfies the requirement pywin32 (from versions: none)
ERROR: No matching distribution found for pywin32
Note: you may need to restart the kernel to use updated packages.

Instead of using Jupyter, write it in CMD. In CMD, chase the exact directory of pip by writing cd and then the location of pip.
This might work.

Why is the curses module not installing via pip?

I have been trying to install the curses module using the command "pip install windows-curses" but it does not seem to be working and it errors out saying:
ERROR: Could not find a version that satisfies the requirement windows-curses (from versions: none)
ERROR: No matching distribution found for windows-curses
[Edit: I am using python 3.10]
I installed the requests package after that using pip but that seems to install perfectly. So, pip is working correctly, just not the curses module. Is it a problem on my end or is this package actually not available?

Currently the latest version of windows-curses is 2.2.0 and it provides wheels for Python 3.6-3.8 and no source code.
Most probably you use Python 3.9 or 3.10 (you should have indicated in the question). To use windows-curses you need to downgrade. You can also download wheels from https://www.lfd.uci.edu/~gohlke/pythonlibs/#curses

How to install pyramid-arima in python 3.7

I'm trying to implement auto arima in my python 3.7 on Windows10 So I tried to install pyramid-armia using following command
pip install pyramid-arima
But I'm getting error message
Could not find a version that satisfies the requirement pyramid-arima (from versions: )]
No matching distribution found for pyramid-arima
I also tried steps mentioned here
But got the same error message
Can you please guide me to install it?

This error might be because there is no version of package that fits combination of versions of your Python, Operating System, Cpu Type and Instruction Set.
That package is out-dated and abandoned, hence not installable, use new replacement, which is pmdarima package:
pip install pmdarima
and import like:
import pmdarima
Official documentation for pmdarima is here.
If still you're getting same error for new pmdarima then download .whl package directly from here.
You need to download package corresponding to your python version and windows bits. E.g. if you have Python 3.7 and Windows 64-bit then download pmdarima-1.7.1-cp37-cp37m-win_amd64.whl (or with win32 suffix for 32-bit windows), here cp37 means CPython version 3.7.
Then just install it like this:
pip install pmdarima-1.7.1-cp37-cp37m-win_amd64.whl
Also many trouble-some Windows prebuild .whl packages that have problems with installation/compilation are located here. I've often downloaded this prebuilt packages from there, when haven't succeeded with pip install. But for the case of pmdarima it is located at the first link but not second.

Python 3.8.5 and MYSQLDB

As of late, I have been attempting to setup MySQLDB on Pycharm. I have Python 3.8.5 installed, have made sure the PATH is set, and everything seems to be working handily. After this, I ran the pip command.
python -m pip install mysqldb
and
python -m pip install mysqldb-python
But to no avail.
I tried to install it from Pycharm's interpreter page, but also no dice. I also attempted to install using a .whl file, but that has also turned out a failure. I've searched far and wide for the last few days, and I've found mention of this error, but none of the fixes I've seen have truly worked. The error I get is the same, regardless of which iteration I attempt to install. And of all the guides I see, I never see any mention of steps I've missed or things I should have done before attempting an installation aside from what I've done. The error is as follows.
ERROR: Could not find a version that satisfies the requirement MySQLdb (from versions: none)
DEPRECATION: The -b/--build/--build-dir/--build-directory option is deprecated. pip 20.3 will remove support for this functionality. A possible replacement is use the TMPDIR/TEMP/TMP environment variable, possibly combined with --no-clean. You can find discussion regarding this at https://github.com/pypa/pip/issues/8333.
ERROR: Could not find a version that satisfies the requirement MySQLdb (from versions: none)
ERROR: No matching distribution found for MySQLdb

you can try installing the following,
pip install pymysql
pip install mysql-connector
pip install mysql-connector-python
or you can go to lfd.uci.edu/~gohlke/pythonlibs/#mysql-python and install the wheels.

It looks like you're using the wrong package to try to install mysqldb through pip. I tried it and got the same error you did this tells me that pip is looking for a package to download and install, but cannot find it.
Try this instead:
pip install MySQL-python
You can learn more about this package here:

'requirement tdd' issue when installing 'micom' PyPI on the PyCharm enviroment

I tried to install a PyPI named micom in the PyCharm environment.
But, when I wrote code on the python terminal as
pip install micom
The following error is showing:
ERROR: Could not find a version that satisfies the requirement tbb (from versions: none)
ERROR: No matching distribution found for tbb
My pip version is the latest (v20.1.1)
I thought there is some problem in umap-learn or tdd, so I tried to install both through project interpreter + at the PyCharm, but it didn't work with same error ;
ERROR: Could not find a version that satisfies the requirement tbb (from versions: none)
ERROR: No matching distribution found for tbb
I have done Googling, but it is not easy to find troubleshooting about this tdd issue.
Can you give me any advice on this issue?

One of the dependencies of micom is umap-learn>=0.4.1. The latter relies on tbb. Somehow, when trying to install umap-learn, the installation fails on installing tbb. That seems to be a known issue. I suggest to follow the advice of an answer posted there:
This has been an intermittent problem that I have had difficulty
tracking down. In the worst case you can grab the latest version off
github and, prior to installing, just remove tbb from the requirements
(including in setup.py). That should resolve the problem and it will
likely work without tbb for the most part.
That would entail cloning the latest version of umap-learn from GitHub and removing the tbb requirement from requirements.txt and setup.py. You can then try to install umap-learn by running pip install . in the root of the cloned GitHub repository.
