[SOLVED]Does not Compile in the Particle DEV

I don’t know why the Particle DEV does not compile. After clicking in the button that says compile in the cloud it gives me error that are not in the current sketch.

Make sure your directory contains only the files required for your project, since it will send the entire folder over to compile. Any ‘strange’ files will thus cause errors.

Many thanks.
I’ve just solved it.
