Javascript 如何在typescript中使用同构获取

我收到错误@types/isomorphic fetch没有默认的导出fetch

import fetch from 'isomorphic-fetch';

export const AUTH_FAIL = "AUTH_FAIL"
export const ERROR_FETCH = "EROR_FETCH";
export const SUCCESS_FETCH = "SUCESS_FETCH";
export const START_FETCH = "START_FETCH";

export function start_fetch(){ 
    return function(dispatch: any){
        return fetch("http://localhost:8000/api/data")
        .then(
            response => response.json()
        )
    }
}

谢谢您的帮助。

我可以通过如下方式导入库使其正常工作：

import 'isomorphic-fetch';

在那之前，我必须履行ES6承诺。例如：

import * as e6p from "es6-promise";
(e6p as any).polyfill();

您是否尝试使用npm安装它？npm安装@types/isomorphic fetch和import fetch，如下所示：import*作为fecth从“isomorphic fetch”导入；
