If you build Atom from source and you’re having an issue with the Command Palette, there was a breaking change accidentally released in v0.28.0 of the Command Palette package. Just update Atom to the latest
master (any time after
28eb03e) and do a clean build to fix it.
Released/downloaded versions of Atom do not run into this issue.
See the Issue for details:
Instructions on how to perform a clean build against the latest
