Failed to check node env due to polyfill.

[ZhUyU1997]

I am using axios on node.js (4.x). It has the logic that checks if node env. It failed because of polyfill.

function getDefaultAdapter() {
  var adapter;

  if (typeof XMLHttpRequest !== 'undefined') {
    // For browsers use XHR adapter
    adapter = xhr;
  } else if (typeof browser$1 !== 'undefined' && Object.prototype.toString.call(browser$1) === '[object process]') {
    // For node use HTTP adapter
    adapter = http_1;
  }
  console.log("getDefaultAdapter", adapter,)
  return adapter;
}

browser$1 is defined by polyfills/process-es6.js. But I think we should not inject it if using node.js.

var browser$1 = {
  nextTick: nextTick,
  title: title,
  browser: browser,
  env: env,
  argv: argv,
  version: version,
  versions: versions,
  on: on,
  addListener: addListener,
  once: once,
  off: off,
  removeListener: removeListener,
  removeAllListeners: removeAllListeners,
