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

If using babel-preset-stage-2 then just have to start the script with --require babel-polyfill.

In my case this error was thrown by Mocha tests.

Following fixed the issue

mocha \"server/tests/**/*.test.js\" --compilers js:babel-register --require babel-polyfill
