pod install问题：Failed to connect to 127.0.0.1 port 9743: Connection refused

今天在pod install 时，碰到如下问题

[!] Error installing AFNetworking

[!] /usr/bin/git clone https://github.com/AFNetworking/AFNetworking.git /var/folders/mn/13sgrc_946nf7wmcybsfcd700000gn/T/d20161123-2910-ek2lzk --single-branch --depth 1 --branch 3.0.4 --recursive

fatal: unable to access 'https://github.com/AFNetworking/AFNetworking.git/': Failed to connect to 127.0.0.1 port 9743: Connection refused

是git代理的问题，通过浏览器访问该url和port时，也显示连接失败。

最后谷歌搜索通过，

 git config —global http.proxy先找到git代理，确定代理就是该url，

然后利用git config —global —unset http.proxy将git代理去除，再进行安装，顺利通过。
