error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
I had to install lxml‑4.2.3‑cp37‑cp37m‑win_amd64.whl the same way as in the answer of Sushant Chaudhary to successfully complete installation of Scrapy.
Download lxml‑4.2.3‑cp37‑cp37m‑win_amd64.whl from Lxml
put it in folder where Python is installed
install it using pip install <file-name>
Now you can run pip install scrapy.
I had the same exact issue on my windows 10 python version 3.8.
In my case, I needed to install mysqlclient were the error occurred Microsoft Visual C++ 14.0 is required. Because installing visual studio and it's packages could be a tedious process, Here's what I did:
step 1 - Go to unofficial python binaries from any browser and open its website.
step 2 - press ctrl+F and type whatever you want. In my case it was mysqlclient.
step 3 - Go into it and choose according to your python version and windows system. In my case it was mysqlclient‑1.4.6‑cp38‑cp38‑win32.whl and download it.
step 4 - open command prompt and specify the path where you downloaded your file. In my case it was C:\Users\user\Downloads
step 5 - type pip install .\mysqlclient‑1.4.6‑cp38‑cp38‑win32.whl and press enter.
Thus it was installed successfully, after which I went my project terminal re-entered the required command. This solved my problem
Note that, while working on the project in pycharm, I also tried installing mysql-client from the project interpreter. But mysql-client and mysqlclient are different things. I have no idea why and it did not work.
I had a similar situation installing pymssql.
pip was trying to build the package, because there were no official wheels for Python 3.6 and Windows.
I solved it by downloading an unofficial wheel from Unofficial Windows Binaries for Python Extension Packages.
Specifically for your case: MySQL-python
I just had the same issue while using the latest Python 3.6. With Windows OS 10 Home Edition and a 64-bit operating system.
Steps to solve this issue:
Uninstall any versions of Visual Studio you have had, through Control Panel
Install Visual Studio 2015 and chose the default option that will install
Visual C++ 14.0 on its own
You can use PyCharm for installing Scrapy: Menu Project → Project Interpreter → + (install Scrapy)
Check Scrapy in the REPL and PyCharm by import. You should not see any errors.

None of the solutions here and elsewhere worked for me. It turns out an incompatible 32-bit version of mysqlclient is being installed on my 64-bit Windows 10 OS because I'm using a 32-bit version of Python.
I had to uninstall my current Python 3.7 32 bit, and reinstalled Python 3.7 64 bit and everything is working fine now.
If Visual Studio is NOT your thing, and instead you are using VS Code, then this link will guide you thru the installer to get C++ running on your Windows.
You only needs to complete the Pre-Requisites part.
https://code.visualstudio.com/docs/cpp/config-msvc/#_prerequisites
This is similar with other answers, but this link will probably age better than some of the responses here.
PS: don't forget to run pip install --upgrade setuptools

I tried ALL of the above and none worked. Just before before signing up for the booby hatch, I found another reason for the error : using the wrong shell on Windows.
conda init cmd.exe
did the trick for me. Hope it may save someone else, too.
I was facing the same problem. The following worked for me:
Download the unofficial binaries file from Christoph Gohlke installers site as per the Python version installed on your system.
Navigate to the folder where you have installed the file and run
pip install filename
For me python_ldap‑3.0.0‑cp35‑cp35m‑win_amd64.whl worked as my machine is 64 bit and Python version is 3.5.
This successfully installed python-ldap on my Windows machine. You can try the same for mysql-python.
I had the same problem. I needed a 64-bit version of Python so I installed 3.5.0 (the most recent as of writing this). After switching to 3.4.3 all of my module installations worked.

I had the same issue while installing mysqlclient for the Django project.
In my case, it's the system architecture mismatch causing the issue. I have Windows 7 64bit version on my system. But, I had installed Python 3.7.2 32 bit version by mistake.
So, I re-installed Python interpreter (64bit) and ran the command
pip install mysqlclient
I hope this would work with other Python packages as well.
TLDR run vcvars64.bat
After endlessly searching through similar questions with none of the solutions working.
-Adding endless folders to my path and removing them. uninstalling and reinstalling visual studio commmunity and build tools.
and step by step attempting to debug I finally found a solution that worked for me.
(background notes if anyone is in a similar situation)
I recently reset my main computer and after reinstalling the newest version of python (Python3.9) libraries I used to install with no troubles (main example pip install opencv-python) gave
is not a full path and was not found in the PATH.
after adding cl to the path from
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.27.29110\bin\Hostx64\x64
and several different windows kits one at a time getting the following.
The C compiler
"C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.27.29110/bin/Hostx64/x64/cl.exe"
is not able to compile a simple test program.
with various link errors or " Run Build Command(s):jom /nologo cmTC_7c75e\fast && The system cannot find the file specified"
upgrading setuptools and wheel from both a regular command line and an admin one did nothing as well as trying to manually download a wheel or trying to install with --only-binary :all:
Finally the end result that worked for me was running the correct vcvars.bat for my python installation namely running
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat" once (not vcvarsall or vcvars32) (because my python installed was 64 bit) and then running the regular command pip install opencv-python worked.
