Errors when running grunt package-dev

[patdelaney]

I'm not a "developer", but I can figure thigs out. But when I run: grunt package-dev, I get the following errors. Should I be concerned? `C:\dev\Pickerfield\PickerFieldsControl>grunt package-dev Running "ts:build" (ts) task Compiling... Using tsc v2.9.2
