CLI tests are throwing an error:

ERROR in /tmp/storybook/node_modules/safe-eval/index.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):
Error: Requires Babel "^7.0.0-0", but was loaded with "6.26.3". If you are sure you have a compatible version of @babel/core, it is likely that something in your build process is loading the wrong version. Inspect the stack trace of this error to look for the first entry that doesn't mention "@babel/core" or "babel-core" to see what is calling Babel.
