Ember-cli: ember addon test-addon -> EACCES: permission denied, open ...package.json

[rfbarber]

I receive the following error when attempting to create a new addon:

EACCES: permission denied, open '/usr/local/lib/node_modules/ember-cli/blueprints/addon/files/package.json'

This is a long running issue, yes we should fix.

On the flip side, /usr/local/lib/node_modules should most likely be writable by your current user, rather then root.

I got bit by this recently. Here's a guide to fixing permissions that helped me.

Thank you for reporting it! The guide mentioned above is the recommended solution for this problem :)
