"build-essential" are needed for proper install on Linux (#9573)
"build-essential" are needed for proper install on Linux (#9573)

On a fresh install of Windows Subsystem for Linux (Ubuntu 20.04), created a conda environment and tried to follow the above guide  to install airflow but was getting gcc errors. Installing build-essential solved the issue.  

On Windows 10, with a clean conda environment, setproctitle fails to install with error "Microsoft Visual C++ 14.0 is required". Suggests to install "Microsoft Visual C++ Build Tools".  I got this both on Python version 3.8.3 and 3.5.6

May be add some prerequisites about Windows and Python versions?
