Building failed after update to alpha13

Version Ide 2.0.0-alpha13, Core 3.3a17

This happens with avr and teensy after building first without upload. When I tried with upload, then it works, and also building is ok.

Thanks a lot for the report! Fixed in Alpha.14. Please restart Atom and apply the updates.

P.S: Would be thankful for any bug reports. I’ve rewritten IDE 2.0 from scratch a few days ago using React. We are so close for the first public beta release. Maybe next week.
