1、先查找一下自己的代理

$ npm config get proxy
$ npm config get npm config get https-proxy
$ npm config get registry

2、然后将代理和缓存置空

方式一：

$ npm config set proxy false
$ npm cache clean --force

方式二：

$ npm config set proxy null
$ npm config set https-proxy null

3、配置新的镜像源，选一个就行

# 淘宝源（推荐）
$ npm config set registry http://registry.npm.taobao.org/

# 官方源
$ npm config set registry http://registry.npmjs.org/
$ npm config set registry https://registry.npmjs.org/

# cnpm 源
$ npm config set registry https://registry.cnpmjs.org/
# 如果使用 cnpm，注意是否安装了 cnpm，cnpm 走推荐走的也是淘宝源
$ npm install -g cnpm --registry=https://registry.npm.taobao.org/
