node.js async await - error regeneratorRuntime

问题

I learnt how to use promises in a browser but when I want to use it in my node.js it throw error.

 var _ref = _asyncToGenerator( /*#__PURE__*/regeneratorRuntime.mark(function _callee(url) {
                                           ^
ReferenceError: regeneratorRuntime is not defined

node version

v10.4.1

I use babel for export and import syntax with settings like here in starting file

require('babel-register')({ 
    presets: [ 'env' ]
})

回答1:

babel-polyfill is required. You must also install it in order to get async/await working.

Here explain better Babel 6 regeneratorRuntime is not defined

回答2:

Presumably you are trying to use async / await syntax? You will need to install transform-async-to-generator plugin and include it in your Babel config

require('babel-register')({
  presets: ['env'],
  plugins: ['transform-async-to-generator']
})
