问题描述：

问题发生在阶段一的第五周，5-2 脚手架请求项目模板API开发 这一节

我跟着视频写的代码但还是会显示 Error: connect ECONNREFUSED 127.0.0.1:7001

我使用的操作系统是win10

麻烦老师解答一下。

相关截图：

我在postman上可以通过api获取到数据

imooc-cli-dev里的错误信息：

项目名imooc verb Error: connect ECONNREFUSED 127.0.0.1:7001
项目名imooc ERR! connect ECONNREFUSED 127.0.0.1:7001

相关代码：

request.js

'use strict';

const axios= require('axios')

const BASE_URL= process.env.IMOOC_CLI_BASE_URL ? process.env.IMOOC_CLI_BASE_URL : 'http://localhost:7001';
console.log('BASE_URL',BASE_URL);

const request = axios.create({
    baseURL:BASE_URL,
    timeout:7000,
})

request.interceptors.response.use(
    response=>{
        console.log(response.data);
        return response.data;
        
    },
    error=>{
        console.log(error);
        return Promise.reject(error)
    }
)

module.exports = request;

相关代码：

commands/init/lib/get_project_template.js

const request=require("@imooc-cli-dev-zhang/request")

module.exports=function(){
    return request({
        url:'/project/template',
    });
}

相关代码：

commands/init/lib/init.js

    async prepare(){
        // 0 ,判断项目模板是否存在
        const template=await get_project_template();
    }

尝试过的解决方式：

我尝试用以上代码呼叫外部的api，https://jsonplaceholder.cypress.io/todos/1

是正常运行的
