ubuntu 利用pm2自動化部署nodejs服務報錯：pm2 commond not found?

echsystem.json 文件:

{
  "apps": [
    {
      "name": "commic",
      "script": "app.js",
      "env": {
        "COMMON_VARIABLE": "true"
      },
      "env_production": {
        "NODE_ENV": "production"
      }
    }
  ],
  "deploy": {
    "production": {
      "user": "xsy",
      "host": ["120.78.165.227"],
      "port": "19999",
      "ref": "origin/master",

      "env": {
        "NODE_ENV": "production"
      }
    }
  }
}

自己電腦上執(zhí)行: pm2 deploy ecosystem.json production setup,成功

--> Deploying to production environment
--> on host 120.78.165.227
  ○ hook pre-setup
  ○ running setup
  ○ cloning git@gitee.com:xiasiyong/cmmic.git
  ○ full fetch
Cloning into '/home/xsy/www/comic/production/source'...
  ○ hook post-setup
  ○ setup complete
--> Success

發(fā)布的時候:pm2 deploy ecosystem.json production,報錯

xiasiyongdeMacBook-Pro:cmmic xiasiyong$ pm2 deploy ecosystem.json production
--> Deploying to production environment

我的服務器是阿里云,ubuntu 14.04,在服務器端運行PM2 -v 是沒問題的呀?

xsy@iZwz9isotv99f3eth4ow92Z:~$ pm2 -v
2.7.2

在服務器對應的文件夾目錄下面執(zhí)行命令又是OK的,

小弟慚愧,折騰半天沒有結(jié)果,想請教各位大神,我是哪里出問題了?
