ERROR Deployer not found: git

nothing to commit, working tree clean
Error: Git commit failed

_config.yml deploy配置如下:

deploy:
    - type: git
      repo:
         github: xxx,master
         coding: xxxx,master
     - type: baidu_url_submitter
       message: "{{ now('YYYY-MM-DD HH:mm:ss') }} "

 #plugins
plugins:
  - hexo-generator-sitemap
  - hexo-generator-baidu-sitemap
  - hexo-baidu-url-submit

hexo目录删除过，从服务器重新拉取过并且npm install了,git重装过,npm升级过，一律不行，主要出现原因是我添加了hexo-baidu-url-submit，然后出现错误通过搜索引擎也无法解决，我就删除了hexo-baidu-url-submit配置，git就报错了,昨晚也是同样出现过,我用本地备份的_config.yml改了一下就行了，现在却不行

在plugins添加推送百度搜索链接的就成功了，但是git依旧报错。求解决办法

@killrookit

Your settings (_config.yml) seems to have a lot of space.

deploy:
    - type: git
      repo:
         github: xxx,master
         coding: xxxx,master
     - type: baidu_url_submitter
       message: "{{ now('YYYY-MM-DD HH:mm:ss') }} "

Is this correct ?

deploy:
  - type: git
    repo:
      github: xxx,master
      coding: xxxx,master
  - type: baidu_url_submitter
    message: "{{ now('YYYY-MM-DD HH:mm:ss') }} "

Also , how about this issue ?
