由于某种原因，分段错误使我的网站甚至无法加载第一页。我重新安装了红宝石，更新了宝石，重新安装了postgresql和nginx，检查了我的nginx.conf文件，并查看了日志。目前我只通过RVM安装了一个Ruby 2.3.1，而IRB就像魅力一样。乘客说预加载器发现错误。
从它的外观来看，它使用的是Ruby 2.0.0p648解释器，但2.3.1是唯一安装的版本。我能以某种方式改变吗？我已经设置了rvm使用和--default到2.3.1，这就是它所显示的内容，但它会以某种方式不断回到2.0.0。似乎RVM的设置不会更新。我很难过。
An error occurred while starting up the preloader. It exited before signalling successful startup back to Phusion Passenger. Please read this article for more information about this problem.

最初安装它时，看起来你的pg gem是针对2.0.0p648编译的。只需运行
gem uninstall pg
rvm使用ruby_2_3_1（切换到Ruby 2.3.1）
gem install pg（这应该根据Ruby 2.3.1重新编译）
还在乘客配置文件中指定ruby版本。
passenger_ruby /Users/rich/.rvm/gems/ruby-2.3.1/bin/ruby;
答案 1 :(得分：1)
原来你不能直接指向硬二进制文件。 RVM需要指向包装器的指针，因此这是最终路径：passenger_ruby /Users/rich/.rvm/wrappers/default/ruby，它是指向passenger_ruby /Users/rich/.rvm/wrappers/ruby-2.3.1/ruby的指针。测试了两个应用程序，它现在完全有效。命令brew info nginx --with-passenger输出错误的ruby位置。
