Babel 6 regeneratorRuntime is not defined

Question

I\'m trying to use async, await from scratch on Babel 6, but I\'m getting regeneratorRuntime is not defined.

.babelrc file

{
    \"presets\": [ \"es2         


        

Answer 1

I had a setup
with webpack using presets: ['es2015', 'stage-0']
and mocha that was running tests compiled by webpack.

To make my async/await in tests work all I had to do is use mocha with the --require babel-polyfill option:

mocha --require babel-polyfill
