HELP: 'failed with nonezero exit code"

Hi Forum!

I’m currently working on my fist audio plugin. nothing too special, but when attempting to create an AU file I keep getting an error that says command ‘PhaseScriptExecution failed with nonzero exit code’.

I am unsure of what this means and what the issue could have.

Is there anyway anyone out there knows anything about this error?

Might help:
