回形针错误：未初始化的常量Paperclip（NameError）

Question

Trying to install paperclip (the cloudfiles fork), but getting an error:

 config/enviroments/development.rb:28:in 'block in <top (required)>': uninitialized constant Paperclip (NameError)

This is how I installed everything.

gemfile:

gem 'cloudfiles', '>=1.4.9'
gem 'paperclip-cloudfiles', '~>2.3'

config/environment.rb

config.gem 'paperclip-cloudfiles', :lib => 'paperclip'

config/enviroments/development.rb

Paperclip.options[:command_path] = "/ImageMagick/6.6.9-Q16/" #ImageMagick is at c:/ImageMagick/..

Answer 1

I'm not sure if this will solve your problem, but if you're using Bundler, you don't need to call config.gem in your environment.rb. Maybe instead you should do:

gem 'paperclip-cloudfiles', '~>2.3', :require => 'paperclip'

Answer 2

In your gemfile you could try:

gem 'paperclip', :git => "git://github.com/minter/paperclip.git"

As Jack Chu stated you shouldn't need to list the gem in your environment.rb
