Problem with Arduino Sketch


I encounter a problem like this when i try to verify my sketch:
I get Arduino 1.6.12
Teensyduino 1.31
Teensy 2.0 ++

Thank you so much

Where did you get the sketch and maybe go get the matching Library to go with it.

Just a thought

Thank you for your answer.

I get from

and I already checked that, but it seems installed.

The error here is that the zip does not contain a valid library. (under windows)
Maybe open an issue on the git source.

Its also a teensy issue so maybe dive over to the teensy site forums too.
