goog.globalEval not available when running expo start --web

[saikyun]

When following the steps in the readme, and running yarn start --web rather than yarn start, I get the following error:

uncaught Error: goog.globalEval not available
    at Object.../../../../../../../../../Users/jona/jobb/reagent-expo/app/index.js.goog.globalEval (bundle.js:1561)

Tried to play around with different versions of RN/expo etc, but can't seem to solve it.
