error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": https://visualstudio.microsoft.com/downloads/
i went ahead and downloaded Microsoft C++ Build Tools
What should i install? Since there's a bunch of stuff
Because you are using windows, cython based dependencies, Uvloop and Httptools in this case, are not installable. So instead of pip install uvicorn[standard], just go with pip install uvicorn and it will work fine.
