Node.js 仅当作为服务运行时，车把查找失败

在项目根目录中通过npm运行时，无论是在本地还是在服务器的计算机上，我都没有问题，但在作为服务运行时，Handlebar无法找到我的视图文件，并将此错误输出到我的日志：

server listening...
Connected
Error: Failed to lookup view "home" in views directory "/views"

我有一个非常标准的配置文件：

description "dop webserver"
author      "Mike Pawlak"

start on started mountall
stop on shutdown

# automatically respawn

respawn
respawn limit 99 5

script

    export HOME="/root"
    exec /usr//bin/nodejs /var/www/dopWeb/bin/www >> /var/log/node.log 2>&1

end script

和目录结构-

• 项目根
  • 公开的
  • 节点模块
  • 路线
  • 垃圾箱
    • 万维网
  • 观点
    • 布局
      • 主要
    • 家
  • index.js

Index.js代码：

...

//rendering engine setup
var handlebars = require('express-handlebars')
  .create({defaultLayout: 'main'});
app.engine('handlebars', handlebars.engine);
app.set('view engine', 'handlebars');

...

app.get('/', function(req, res) {
        res.render("/home");
})

...

我从来没有弄明白这一点，而是去了，并建立了我的服务
