I am installing psycopg2 for my Django project to connect with Postgres but got the following error:
When I run this:

How do I fix this error?

The error says:
Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/
Install this "Build Tools for Visual Studio", probably by following that link.

I have Microsoft Visual C++ 14.0.25 is installed in my system.
If someone knows any better tool/framework/package for testing api using python please help me. I want to check the registration api with many users at a time.

If Dmitri's suggestion doesnt help, you might want to try this:
pip install -U setuptools
And update to latest locust:
pip install -U locust
(Edit: locust package name is now ”locust”, not ”locustio”)

What you need is not Visual Studio, you need Visual C++ build tools
You can install it using using Visual Studio Installer, you just need to tick the relevant box under the C++ components:

Are you sure you need the 'mysql' package from pip and not the following:
pip install mysql-connector

Failed with pip install chompack

I'm trying to install chompack with pip to use in a Support Vector Machine algorithm with cvxopt. However it gives me an error for which I haven't found a clear answer. There is a related question but the answer provided is very specific to the package the person is trying to install. In my case, there's no binary package that I can download or even a .whl file.
The specific error seems to be
error: command '"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\cl.exe"' failed with exit status 2
Here's what I typed in the command prompt (Windows 10 PC) and the full result.
pip install chompack

I do not know the precise reason but you should use python itself to install packages as chompack:
python -m pip install chompack
For further informations read the manual: https://docs.python.org/3/installing/
PS: I have seen the same message but it installed it anyway.
