If you are building a debug version of Swift, you should also install the Python debug binaries. Alternatively, in the Visual Studio installation program, under Individual Components, install Python 3 64 bits (3.7.x). The command above already installs Python 3. The following link helps in finding the component name given its ID for Visual Studio 2019. The components listed above are required. If you prefer you can install everything by hand, but make sure to include "Programming Languages|Visual C++" and "Windows and Web Development|Universal Windows App Development|Windows SDK" in your installation.
