...arr 改成 [].slice.call(arr)

已解決

    axios.all(_array).then(axios.spread(function () {
                        var responses = Array.from(arguments) 
                        console.log(arguments)
 }));

"use strict";

axios.all(_array).then(axios.spread(function () {
  for (var _len = arguments.length, responses = Array(_len), _key = 0; _key < _len; _key++) {
    responses[_key] = arguments[_key];
  }

  console.log(responses);
}));

這個(gè)是 babel 官網(wǎng)的轉(zhuǎn)義結(jié)果
