undefined method for enumerable
Clone this wiki locally
The Radiant site is installed, properly configured and the database is correctly initialized. But the pages cannot be displayed, instead the following error message appears when you try to access a page in your web browser:
undefined method `' for #<Enumerable::Enumerator:0x........>
As pointed out by Akira Yamada in this thread on the Debian Bugs Dist List, the error comes from an incompatibility between Ruby 1.8.7 and Rails 2.0.2. Ruby 1.8.7 has
String#chars and returns an Enumerator object, but Rails 2.0.2 expects an
ActiveSupport::Multibyte::Chars object. Since older versions of Radiant used Rails 2.0.2, these versions are also affected by this problem.
You can either upgrade to the latest version of Radiant or apply the following fix.
Add following code to the top of the
config/environment.rb file in your Radiant application.
unless '1.9'.respond_to?(:force_encoding) String.class_eval do begin remove_method :chars rescue NameError # OK end end end
