I need to download the package psycopg2 in order to work with the postgresql database in use. Unfortunately, when I try to pip install psycopg2 the following error pops up:

I'am trying to install mysqlclient in Pycharm. But i couldn't,its showing me these errors.There are errors while buliding wheel for mysqlclient. Django version is 3.2.18. Pip version is 21.3.1. Does this error happens due to mismatch of versions of pip and mysqlclient? ............................................................................................................
why don't use the MSI setup file to install it. it's okay with pip, I will check what is the problem, but for the time being go here & install: https://dev.mysql.com/downloads/installer/
MySQL client installs the full suite in your machine (including the CLI). You said about PyCharm, it is going to use the CLI. So just install the full suite setup.
See, I just did this,
PS C:\Users\Archisman> pip install mysqlclient
Collecting mysqlclient

PS C:\Users\Archisman>
I had installed MySQL through the setup file & works everywhere. So, just download the setup & install it. pip install mysqlclient may leave some of the packages to be installed & that's causing the error.
Also don't forget that MySQL needs MS Visual Studio Build Tools. So, it's better run the setup.
UPDATE
Found this in your Shell:
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
Just what I guessed.
As the error messages indicate, The problem could be the "Microsoft Visual C++ Build Tools". So try installing that depandency.

tl;dr Use the official Python distribution for Windows, or use Anaconda.
You should not use python-igraph with the Python included in MSYS2 unless you have a very good reason. This Python is not compatible with the official Python distribution on Windows, which means that you will not be able to install binary wheels from PyPI, and will need to compile everything from source. As you discovered, that is not always trivial.
If you have a truly good reason to use this Python with igraph, the simplest way is the following:
Make sure you are using the appropriate subsystem (i.e. you launch the correct terminal). Here I am assuming you are using the MinGW64 one.
Install the igraph C library from MSYS2: pacman -S mingw-w64-x86_64-igraph
Make sure you are using pip from MSYS2: pacman -S mingw-w64-x86_64-python-pip
Install texttable: pip install texttable
Install igraph, and link to the existing C library: pip install igraph --install-option="--use-pkg-config"
By going this route, you are treading in uncharted waters. Expect problems that you will need to resolve on your own.

There is no package on pypi for the 32-bit version of Python. Only for 64-bit Python.
And if you install mysqlclient from there, naturally, sources that need to be compiled will be installed.
And for 32-bit Python, the compiled package is available at https://www.lfd.uci.edu/~gohlke/pythonlibs/.

WARNING: You are using pip version 19.2.3, however version 19.3.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
It seems it is a problem with the MSBuildTools. I've installed the build tools as instructed on the CVXPY-webpage: https://drive.google.com/file/d/0B4GsMXCRaSSIOWpYQkstajlYZ0tPVkNQSElmTWh1dXFaYkJr/view
That didn't work. Then I found this question (Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualst udio.com/visual-cpp-build-tools) and modified the build tools installation accordingly but it still doesn't work. I don't have the python developement under Web & cloud as in the screenshot, but this should be optional anyway.
Could you please help me?
P.S.: Das System kann die angegebene Datei nicht finden roughly translates to The system can't find the specified file
EDIT: Here's the build tools installation, just in case:
I was facing the same issue. From the link https://www.lfd.uci.edu/~gohlke/pythonlibs/#osqp (posted by phd), downloaded the corresponding version of osqp and install it using (for instance):
pip install osqp-0.6.1-cp38-cp38-win_amd64.whl
Then, you should be able to simply install cvxpy using
pip install cvxpy
I am one of the developers. OSQP pip wheels for python 3.8 are online now. It should fix your problem.

I'm on windows 10 using python 3.5 and django 1.9 , and I want to connect django to mysql database . When I run django server I get : No module named 'MySQLbd'
MySQL-Python does not support Python 3.x. According to the official Django documentation you can use one of the following drivers:
The Python Database API is described in PEP 249. MySQL has three prominent drivers that implement this API:
MySQLdb is a native driver that has been developed and supported for
over a decade by Andy Dustman.
mysqlclient is a fork of MySQLdb which
notably supports Python 3 and can be used as a drop-in replacement for
MySQLdb. At the time of this writing, this is the recommended choice
for using MySQL with Django.
MySQL Connector/Python is a pure Python
driver from Oracle that does not require the MySQL client library or
any Python modules outside the standard library.
