【问题描述】：
我正在尝试使用 S3 上传图片，但是当我创建 config/initializers/carrierwave.rb
并添加
CarrierWave.configure do |config|
config.fog_credentials = {
# Configuration for Amazon S3 should be made available through an Environment variable.
# For local installations, export the env variable through the shell OR
# if using Passenger, set an Apache environment variable.
#
# In Heroku, follow http://devcenter.heroku.com/articles/config-vars
#
# $ heroku config:add S3_KEY=your_s3_access_key S3_SECRET=your_s3_secret S3_REGION=eu-west-1 S3_ASSET_URL=http://assets.example.com/ S3_BUCKET_NAME=s3_bucket/folder
# Configuration for Amazon S3
:provider => 'AWS',
:aws_access_key_id => ENV['S3_KEY'],
:aws_secret_access_key => ENV['S3_SECRET'],
#region => ENV['S3_REGION']
}
# For testing, upload files to local `tmp` folder.
#if Rails.env.test? || Rails.env.cucumber?
# config.storage = :file
# config.enable_processing = false
# config.root = "#{Rails.root}/tmp"
#else
# config.storage = :fog
#end
# To let CarrierWave work on heroku
config.cache_dir = "#{Rails.root}/tmp/uploads"
config.fog_directory = ENV['S3_BUCKET_NAME']
# Generate http:// urls. Defaults to :authenticated_read (https://)
#config.s3_access_policy = :public_read
#config.fog_host = "#{ENV['S3_ASSET_URL']}/#{ENV['S3_BUCKET_NAME']}"
end
rails s 甚至没有启动
我遇到了一堆这样的错误..
=> Booting WEBrick
=> Rails 4.2.0 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

【问题讨论】：
-
是否设置了
S3_KEY、S3_SECRET和S3_BUCKET_NAME？ -
@KenStipek 是的。我为 heroku 和我的 application.yml 文件设置了它们
-
如果你打开rails控制台并运行
puts env['S3_KEY']它会吐出密钥？ -
当我这样做的时候不会给我一个错误
