Hexo deploy did not respond!

  node.js, question

For example, if I open localhost:4000 locally, I can also open hexo interface. At the end of the configuration file inside was also modified.

 type :github
 repository  : https://github.com/MrKou47/Blog.git
 branch :master

Ssh is also available locally and on git, and then executing hexo d is not reflected! One second after execution or the original interface .. Solve!

Tears ran ~

I recreated ssh and found the following. What is the situation?

may be you shouldnpm install hexo-deployer-git --save
