Paperclip gem not working in Production

Question

My rails app works great in development. In production I get the following error when launching the app at Heroku:

It references a helper method I defined:

def image_for(movie)
  if movie.image.exists?
    image_tag(movie.image.url)
  else
    image_tag('placeholder.png')
  end
end

This started after installing the paperclip gem but it doesn't happen in development. Does anyone know how to fix this error. My next step is to install an older version of the gem but I wanted some advice first. Thanks for reading.

Answer 1

Did you put gem 'aws-sdk' in your Gemfile ? It seems Rails can not find Paperclip::Storage::S3::AWS which is provided by aws-sdk gem.

Answer 2

我通过降级AWS-SDK gem修复了此错误：gem'aws-sdk'，'<2.0'
