Magento 2.0.3 fresh install unable to change to developer mode following step by step developer documentation

Question

i just did an fresh install (web installer) of magento 2.0.3. When trying to switch to developer mode by using

magento deploy:mode:set developer

http://devdocs.magento.com/guides/v2.0/frontend-dev-guide/themes/theme-create.html

is returning the following failure:

There are no commands defined in the "deploy:mode" namespace.

Any ideas?

Answer 3

For me there was an error in my of my custom modules' constructor. For anyone else experiencing this, look through your version control logs about update's you've done recently that may have broken this.
