It seems there is an issue with the new library update, several verified community libraries are not working on Particle Build (but they do work on Particle Dev.)
For example, when working with Neopixel, it shows this error message now:
lib/neopixel/examples/a-rainbow/a-rainbow.cpp:8:22: Particle.h: No such file or directory
Can anyone point to the solution to this problem? It seems Particle Build tries to also compile the code in /examples, which is unnecessary.
