[JamesLMilner]

Enhancement

When dojo or associated commands are run in a directory without a package.json file, the CLI throws errors such as Path must be a string. Received null

Package Version: 3.0.0

Code

dojo or dojo init in any directory without a package.json

Expected behavior:

The CLI to either behave as best as possible or give a meaningful error message if not.

Actual behavior:

Unhelpful end user errors
