Question

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

When I run this:

pip install psycopg2

On Windows, I got this error:

How do I fix this error?

Answer 1

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. https://visualstudio.microsoft.com/downloads/
