"Additional properties are not allowed ('requires' was unexpected)" when trying to build mbed_blinky
I acquired the mbed OS by using "add libraries" and https://github.com/ARMmbed/mbed-os. The project will not build on my FRDM-K66F because of this error which comes from multiple mbed_lib.json files. I've begun removing folders which include features that I don't need but there are a good number of these files. It sounds like it might be a Clang issue,
