I had the same error, unrelated to Keystone, so in case it will help anyone, here is what fixed it…

I was using the Babel transpiler and noticed that my ~/.babelrc had the “transform-class-properties” dependency specified. So, I created a local myproject/.babelrc with only { "presets": ["env"] } inside.

It worked after that!

@PatrickJongmans now there is another error in console of the browser and no UI renders

Uncaught Error: Cannot find module 'aphrodite/no-important'  packages.js:4

tested on MAC OS on fresh keystone-test-project with latest keystone from repo

I have tried to understand whats wrong: When I run the project with npm run dev then change all aphrodite/no-important to aphrodite in node_modules/keystone/*, I see the errors in the console

2016-08-20 22:08:90 error building FieldTypes:
Unknown plugin "add-module-exports" specified in "/private/tmp/keystone-test-project/node_modules/inline-style-prefixer/package.json" at 1, attempted to resolve relative to "/private/tmp/keystone-test-project/node_modules/inline-style-prefixer" while parsing file: /private/tmp/keystone-test-project/node_modules/inline-style-prefixer/static.js

then I install babel-plugin-add-module-exports and after changes there another error

2016-08-20 22:08:60 error building FieldTypes:
Couldn't find preset "stage-0" relative to directory "/private/tmp/keystone-test-project/node_modules/inline-style-prefixer" while parsing file: /private/tmp/keystone-test-project/node_modules/inline-style-prefixer/static.js

than I install needed presets

npm i babel-preset-stage-0

then I make another changes and finally I see

2016-08-20 23:08:18 rebuilt FieldTypes
2016-08-20 23:08:43 rebuilt Signin/index.js
2016-08-20 23:08:28 rebuilt App/index.js

and UI works again

Hi @JedWatson - clearing up node_modules and latest master worked fine. Thanks.
