Question

使用http://www.modrails.com/install.html上的指南，我在rails和phusion-passenger上安装了Ruby，以便使用apache2进行部署。（在ubuntu-server上）（这不是开发服务器）。当我运行“rails -s”时，rails脚本工作正常，但是当我尝试使用apache访问服务器时，我得到“500 - 内部服务器错误”。

来自apache的错误文件：

任何熟悉此错误的人 - 感觉就像帮助我们一样？

据我所知，这个错误是解决问题的关键，但是googeling并没有帮助我。

<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- phusion_passenger/utils (LoadError)

编辑：我发现我的第一个错误是我在apache中的mods-enable文件中写了“bun”而不是“bin”。因此，不要将其指向正确的ruby目录。

我现在得到乘客产生的错误。说以下内容：

Ruby (Rack) application could not be started
Error message:
    no such file to load -- bundler

然后它继续进行长时间的回溯，我会在这里发布一个简短的snippitt：

Answer 1

我遇到了同样的问题，然后通过宝石安装乘客修复了它。

访问Phusion Passenger（mod_rails）网站，获取有关Passenger的完整文档。您需要安装GCC来安装乘客。

通过Gem安装Passenger

gem install passenger

运行apache2的乘客安装脚本

passenger-install-apache2-module

将以下内容放在/etc/httpd/conf.d/passenger.conf中（最好直接从passenger-install-apache2-module输出中复制）

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.2.3/ext/apache2    /mod_passenger.so
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.2.3
PassengerRuby /usr/bin/ruby

Answer 2

尝试在生产机器上运行：

bundle exec rake assets:precompile

在ubuntu上使用apache2在rails上安装Ruby的问题
