设置nvm国内镜像

nvm默认的下载地址是http://nodejs.org/dist/，这是国外的服务器，在国内下载速度很慢。

nvm node_mirror https://npm.taobao.org/mirrors/node/
nvm npm_mirror https://npm.taobao.org/mirrors/npm/

使用 cnpm 加速 npm

npm config rm proxy
npm config rm https-proxy
npm config set registry https://registry.npm.taobao.org

git代理设置方法解决

git config --global http.proxy 'socks5://127.0.0.1:1080'
git config --global https.proxy 'socks5://127.0.0.1:1080'
git config --global --unset http.proxy
git config --global --unset https.proxy
npm config delete proxy
