Thin + EventMachine 无法启动 [英] Thin + EventMachine fails to start

问题描述

在为 sinatra 应用程序加载瘦网络服务器时，我不断收到

While loading a Thin webserver for a sinatra app I keep getting

Unable to load the EventMachine C extension; To use the pure-ruby reactor, require em/pure_ruby'<path>/vendor/bundle/ruby/1.9.1/gems/eventmachine-1.0.0.rc.4/lib/eventmachine.rb:8:in `require': cannot load such file -- rubyeventmachine (LoadError)

在我的 Mac OSX 中，我启动服务器没有任何问题，但在我的服务器中，这是一个红帽企业 Linux 服务器 6.2 版(圣地亚哥)我无法启动我的应用.

In my Mac OSX I boot the server without any problems but in my server which is a Red Hat Enterprise Linux Server release 6.2 (Santiago) I can't start my app.

我使用的是 rvm 1.18.5 和 ruby​​-1.9.3-p374

I'm using rvm 1.18.5 and ruby-1.9.3-p374

推荐答案

我通过卸载自制的 ruby​​ 2.5 版本修复了无法加载 EventMachine C 扩展"错误.请参阅关于 创建数据库时出现Rails/Ruby错误:无法加载EventMachine C扩展

I fixed my "Unable to load the EventMachine C extension" error by uninstalling homebrew's version of ruby 2.5. See this comment on Rails/Ruby Error When Creating Database: Unable to load the EventMachine C extension
