I’m sure this question has been asked hundreds of time but please be kind and help a total newbie to FastLED and Arduino and I can’t seem to find the fix in the FAQ.

I’m trying to get a 60 LED strip working on an UNO using the FastLED DemoReel100 (and other) sketch and I keep getting the following compile error;

‘rainbow’ was not declared in this scope.

I do not have the same issue when using the NeoPixle libraries for some reason, and simple sketches like Cylon have no errors.

Would someone be so kind as to point me in the right direction to fix this issue?

Here is a link to the full error message

Multiple libraries were found for “FastLED.h”
Start by removing the extra/duplicate copies of the library. You only want one version of FastLED.
Also, after downloading and unzipping the FastLED library from github you need to rename the folder from:
FastLED-master
to:
FastLED

It might also be the fact you are using the new beta version of the IDE. Try the stable version

Thanks for the help! Looks like a Mac install issue, moved to PC and all problems resolved, now to fix the Mac.
