问题描述
尝试安装回形针(cloudfiles fork)，但出现错误:
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)
这就是我安装所有东西的方式.
This is how I installed everything.
宝石文件:
gem 'cloudfiles', '>=1.4.9'
gem 'paperclip-cloudfiles', '~>2.3'
config/environment.rb
config/environment.rb
config.gem 'paperclip-cloudfiles', :lib => 'paperclip'
config/enviroments/development.rb
config/enviroments/development.rb
Paperclip.options[:command_path] = "/ImageMagick/6.6.9-Q16/" #ImageMagick is at c:/ImageMagick/..
推荐答案
我不确定这是否能解决您的问题，但如果您使用 Bundler，则无需在您的环境中调用 config.gem.rb也许你应该这样做:
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'
