There is no such file to load - active_support / core_ext (LoadError)

Question

In my rails 2.3.8 application running on Windows 7, the following error appears when trying to start the server:

D:\app1>ruby script/server
C:/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require': no such file to load -- active_support/core_ext (LoadError)
        from C:/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require'
        from D:/app1/vendor/rails/activesupport/lib/active_support.rb:56
        from C:/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
        from C:/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
        from D:/app1/vendor/rails/railties/lib/commands/server.rb:1
        from C:/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
        from C:/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
        from script/server:3

In the user required file block below ... line 36 is the "gem_original_require path"

  def require(path) # :doc:
    gem_original_require path
  rescue LoadError => load_error
    if load_error.message =~ /#{Regexp.escape path}\z/ and
       spec = Gem.searcher.find(path) then
      Gem.activate(spec.name, "= #{spec.version}")
      gem_original_require path
    else
      raise load_error
    end
  end

I looked around part of the error, but I'm not quite sure where to start.

Answer 1

create file name

core_ext.rb

at

 C:\Ruby\lib\ruby\gems\1.8\gems\activesupport-2.3.8\lib\active_support

and edit to add content to the following lines

filenames = Dir["#{File.dirname(__FILE__)}/core_ext/*.rb"].sort.map do |path|
  File.basename(path, '.rb')
end

# deprecated
filenames -= %w(blank)

filenames.each { |filename| require "active_support/core_ext/#{filename}" }

Answer 2

Just looking at the stack trace ... it looks like your application is on drive “D” and the ruby ​​files are on drive “C”.

,

filenames = Dir["#{File.dirname(__FILE__)}/core_ext/*.rb"].sort.map do |path|
  File.basename(path, '.rb')
end

"D", "C". . .
