Question

我正在尝试使用Ruby 1.9.3应用程序（不是rails或web）在Openshift中运行Capybara / PhantomJS测试。它在本地运行良好，但当我尝试bundle exec ruby test.rb时，它输出：

/var/lib/openshift/asdf/app-root/runtime/repo/vendor/bundle/ruby/1.9.1/gems/poltergeist-1.8.1/lib/capybara/poltergeist/web_socket_server.rb:34:in `initialize': Permission denied - bind(2) (Errno::EACCES)
        from /var/lib/openshift/asdf/app-root/runtime/repo/vendor/bundle/ruby/1.9.1/gems/poltergeist-1.8.1/lib/capybara/poltergeist/web_socket_server.rb:34:in `open'
        from /var/lib/openshift/asdf/app-root/runtime/repo/vendor/bundle/ruby/1.9.1/gems/poltergeist-1.8.1/lib/capybara/poltergeist/web_socket_server.rb:34:in `start_server'

        from /var/lib/openshift/asdf/app-root/runtime/repo/vendor/bundle/ruby/1.9.1/gems/poltergeist-1.8.1/lib/capybara/poltergeist/server.rb:20:in `new'

        from /var/lib/openshift/asdf/app-root/runtime/repo/vendor/bundle/ruby/1.9.1/gems/poltergeist-1.8.1/lib/capybara/poltergeist/driver.rb:38:in `server'
    from /var/lib/openshift/asdf/app-root/runtime/repo/vendor/bundle/ruby/1.9.1/gems/poltergeist-1.8.1/lib/capybara/poltergeist/driver.rb:25:in `browser'
    from /var/lib/openshift/asdf/app-root/runtime/repo/vendor/bundle/ruby/1.9.1/gems/poltergeist-1.8.1/lib/capybara/poltergeist/driver.rb:95:in `visit'
    from /var/lib/openshift/asdf/app-root/runtime/repo/vendor/bundle/ruby/1.9.1/gems/capybara-2.5.0/lib/capybara/session.rb:232:in `visit'
    from /var/lib/openshift/asdf/app-root/runtime/repo/vendor/bundle/ruby/1.9.1/gems/capybara-2.5.0/lib/capybara/dsl.rb:51:in `block (2 levels) in <module:DSL>'
    from test.rb:43:in `test'
    from test.rb:58:in `<main>'

我正在使用Poltergeist并手动将其指向phantomjs可执行文件，如Poltergeit's github（从该页面获得的exec，v1.98）中所见，这似乎可以自行运行并具有适当的可执行权限。它与ruby项目位于同一个目录中，因此poltergeis的:phantomjs选项为./phantomjs。

我从输出中看到，vendor / bundle中的Ruby版本是1.9.1，根据Capybara的github不支持，但我不确定这是否相关。

任何想法在这里可能有什么问题，或者如何更好地调试此错误？

看起来您的应用程序（或其中某些部分）正在尝试绑定到不允许的IP地址或端口。您只能绑定到您的openshift IP地址（不是0.0.0.0或127.0.0.1），您的应用程序应该绑定到端口8080，以便它可以公开访问。您可以参考Developer Portal的这一部分（https://developers.openshift.com/en/managing-port-binding-routing.html），以获取有关如何将请求路由到您的应用程序的更多信息。
