Ruby on rails Node.js运行时，轨道位于乘客侧

我正在尝试在ubuntu 14.04上安装nginx+passenger+rails 最大的要求是能够安装不带sudo的node包，实现这一点的最简单方法是为用户安装node，而不是为系统安装afaik。因此，我尝试使用nvm，它对资产编译几乎没有影响，但当我尝试访问网页时，passenger.log中出现了一个错误

`Error details saved to: /tmp/passenger-error-rMZT8N.html
  Message from application: Could not find a JavaScript runtime. See https://github.com/rails/execjs for a list of available runtimes. (ExecJS::RuntimeUnavailable)
/var/www/something/shared/bundle/ruby/2.2.0/gems/execjs-2.6.0/lib/execjs/runtimes.rb:48:in `autodetect'

Nodejs路径在nginx.conf中指定如下

passenger\u nodejs/home/deployer/.nvm/versions/node/v5.2.0/bin/node

但那没用

相反，bundle exec rails s-e staging-b0.0.0工作正常
