简单说明一下报错信息：使用npm install安装任何包都会报错，errno ECONNREFUSED，报错信息如下：

$ npm install --save hexo-blog-encrypt

当我出现这个问题时，以为是镜像源出错，就一直在更换镜像源，结果可想而知，依旧没有解决错误，在不断查找资料发现自己的方向就错了，这个问题的核心错误信息是：

reason: connect ECONNREFUSED 127.0.0.1:31181

问题的原因：

一般来说是访问国外网站工具或者加速器开启了网络代理，修改了相关配置导致 npm连接本机 31181 端口安装包。

首先可以查看一下npm的代理配置：

npm config get https-proxy

http://127.0.0.1:31181/

 然后查看本地的端口没有对应的服务开启：

netstat -ano

 到这基本就可以确定是代理导致的问题。

解决办法：

1.清空相关代理，http-proxy和proxy

npm config delete https-proxy
npm config delete proxy

2.查看配置代理的结果

npm config get proxy
//返回null
npm config get https-proxy
//返回null

由上图可知，当两者都返回null时说明删除成功，此时在修改镜像源才可能有用。

3.之后安装即可

npm i axios
