無法加載EventMachine C擴展;要使用純Ruby反應器

Question

我有麻煩，在Rails項目（redmine2.3），導軌的版本是3.2

啓動項目

bundle exec thin start -p 8080 -e production -s 5 -d 

錯誤信息

(eval):9: warning: already initialized constant Bundler::Dsl::RAILS_VERSION_IS_3 
(eval):9: warning: previous definition of RAILS_VERSION_IS_3 was here

運行時發生同樣的錯誤rails -v

rails -v 
(eval):9: warning: already initialized constant Bundler::Dsl::RAILS_VERSION_IS_3 
(eval):9: warning: previous definition of RAILS_VERSION_IS_3 was here 

在項目運行bundle exec .....產生同樣的錯誤

問題已經解決了，看到我的評論在三樓，有答案

Answer 1

此相關的錯誤信息如下：

Unable to load the EventMachine C extension; To use the pure-ruby reactor, require 'em/pure_ruby' 

嘗試重新安裝eventmachine寶石：

gem uninstall eventmachine 
bundle install 

見Rails/Ruby Error When Creating Database: Unable to load the EventMachine C extension 和 Rails - cannot run app: Unable to load the EventMachine C extension;有關如何處理此問題的更多建議。

Answer 2

問題已修復。

rm vendor/cache/ -rf 
bundle install 

固定錯誤

remove the Redundant folder in the redmine/plugins 

固定的警告

This is record of locating and repairing process.

THX一切！
