ruby 企业版和 Rails<3 应用程序

Question

我正在尝试使用 ruby​​EE 运行 Redmine，但我经常遇到一些 action_controller 问题。 当我运行 unicorn 时，我得到：

/opt/rubyEE-2010-02/lib/ruby/site_ruby/1.8/rubygems.rb:223:in `activate': undefined method `map' for nil:NilClass (NoMethodError)
        from /opt/rubyEE-2010-02/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:35:in `require'
        from /usr/share/redmine/config/environment.rb:34
        from /opt/rubyEE-2010-02/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
        from /opt/rubyEE-2010-02/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'

当我删除供应商目录时，我得到：

# unicorn_rails -c /etc/redmine.ru -E production
I, [2010-12-19T20:52:36.251056 #21117]  INFO -- : listening on addr=0.0.0.0:4000 fd=3
I, [2010-12-19T20:52:36.253061 #21117]  INFO -- : Refreshing Gem list
Missing the Rails 2.3.5 gem. Please `gem install -v=2.3.5 rails`, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out RAILS_GEM_VERSION to use the latest version installed.

Answer 1

您需要删除 Rails 2.3.9，由于没有严格的依赖关系，它们可能会被加载：

gem uninstall actionpack activesupport -v 2.3.9

如果您需要两个版本，您可以使用 rvm 用于更多 ruby​​ 版本，每个项目均可轻松配置。
