Describe the bug

After installing docz, I tried to give a go with the following command:

$ docz dev

and I got the following error:

@pedronauck thanks, although making sure im on babel7 and using this article’s libs and version numbers combinatorially with those shown here seem to result in the same error to no avail.

IMO, in a small org without a person or team dedicated to maintaining RN component documentation, this is a battle not worth fighting. I’ve tried storybookJS, docz, styleguidist, and none of them seem to work consistently, due to webpack, babel, RN versions expo versions, etc. etc. perhaps I shall just wait a bit longer for these issues to resolve over time.

docz-plugin-babel6 was deprecated @hariDasu, we don’t support older version of babel at all
