I keep getting this error. I am trying to upload a sketch to a likenode r4 so I can use it with Alexa but can't get by the switch.h error. looked over the web didn't find much. Tried uninstalling and reinstalling everything. Nothing. Worked before but not now. Am I missing a library or file someplace?

Am I missing a library or file someplace?


Please read "Read this before posting a programming question" at the top of the forum.
Post your sketch (MOD EDIT)

When I look in the Arduino IDE Library Manager, there are two switch libraries, but without seeing your sketch, we can't begin to guess which one you need.

Or the switch library you are looking for isn't in the Library Manager. Can you contact the author of the sketch?
