核心错误信息：

代码语言：javascript复制

reason: connect ECONNREFUSED 127.0.0.1:31181

​

问题原因

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。

确定这个问题可以查看 npm 的代理配置：

代码语言：javascript复制

$ npm config get https-proxy
http://127.0.0.1:31181/

然后查看本地端口没有对应的服务开启 (Windows)：

代码语言：javascript复制

$ netstat -ano

此时基本可以确认就是代理导致的问题。

解决方案

清空相关代理，http-proxy 和 proxy

代码语言：javascript复制

npm config delete https-proxy
npm config delete proxy

查看配置代理结果

代码语言：javascript复制

npm config get proxy
npm config get https-proxy

如果二者都返回 null 说明删除成功

此时修改镜像源才可能有用。

之后安装包就可以了

代码语言：javascript复制

$ npm install --save hexo-blog-encrypt
npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.
