@skwon-mdsol That the purpose of using babel in the first place.
@cattermo I have removed the
babel-polyfill
, The error occurs anytime I use ES6 import.Fixed deleting .babelrc and creating babel.config.js with folow code
@timotew sorry to hear that, I’m stuck as well, I’m having the same exact issue that you have while running Nightwatch (for e2e tests)
@MaximeHeckel There was no solution, I had to revert back to babel 6 on the project.
Same problem here
.babelrc
When i move all the code from bin/www in my app.js in the root everything works…
