请帮助解决此问题

Answer 1

如所述：

npm ERR! git fetch -a origin (git://github.com/felixge/node-mysql.git) fatal: unable to connect to github.com:
npm ERR! git fetch -a origin (git://github.com/felixge/node-mysql.git) github.com[0: 192.30.252.129]: errno=Connection timed out
npm ERR! Error: Command failed: fatal: unable to connect to github.com:
npm ERR! github.com[0: 192.30.252.129]: errno=Connection timed out

对Github.com的请求超时，这意味着您的网络连接不工作或无法从您的位置访问Github，请使用ping github.com的输出更新您的问题

与我的gihub ping相同的问题：
