vue创建项目配置脚手架vue-cli环境出错

1、at process._tickCallback (internal/process/next_tick.js:188:7)  npm ERR! message: 'request to https://registry.npm.taobao.org/vue-cli failed, reason: connect ECONNREFUSED 127.0.0.1:1080',

1）报错信息大概如下：

 E:\WebStormFile\labSystem>npm i -g vue-cli

2）原因：npm配置了代理（可以使用"  npm config list -l  "命令查看npm配置）

3）使用" npm config delete https-proxy "命令删除配置  (https-proxy = "http://127.0.0.1:1080/")就可以正常下载啦
