LoadError（无法加载此类文件-static_helper.rb）：

Question

I'm trying to upgrade an old rails 2.3 app to 2.3.15 and I'm getting the following error after changing the RAILS_GEM_VERSION line in environment.rb

LoadError (cannot load such file -- static_helper.rb):
app/controllers/static_controller.rb:1:in `<top (required)>'
<internal:prelude>:10:in `synchronize'
/Users/bob/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/webrick/httpserver.rb:138:in `service'

Answer 1

Are you using bundler? ( http://gembundler.com/rails23.html ).

I had a different error updating an old rails 2.3 app to 2.3.15 that I was able to work around by setting up bundler and removing config.gem lines from config/environment.rb

Nevermind that Bundler advice, I bet the StaticController expects to find a corresponding helper file. Try creating a file called app/helpers/static_helper.rb :

module StaticHelper
end
