Amazon s3 S3存储因fog 0.7.2和x2B而失败；卡里尔瓦夫主支部

尝试存储文件时，我得到以下信息：

我已经尝试过手动调试，我想知道这个问题是否与@content\u type被设置为nil这一事实有关，尽管我还无法进一步推断

---

这是一个s3（或fog，我没有任何其他提供商）特定的问题，我的项目在使用：文件存储时运行良好。想法？

解决了。我使用的是自述文件中所述的过时配置，而不是文档中所述的新方法

---

新开发人员必须确保阅读实际的RDOC，而不是自述文件。

这个问题让我很头疼。我把这个问题放到

config/initializers/carrierwave.rb

中解决了：

S3\u CONFIG=YAML.load\u文件（Rails.root.join（'CONFIG'，'amazon\u S3.yml'））[Rails.env]
CarrierWave.configure do | config|
config.storage=：s3
config.s3\u访问\u策略=：公共\u读取
config.s3_access_key_id=s3_config['access_key_id']
config.s3_secret_access_key=s3_config['secret_access_key']
config.s3_bucket=s3_config['bucket']
结束

并将其放入

config/amazon_s3.yml

：

development:
  access_key_id: xxxxxxxxxxxxxxxxxxxx
  secret_access_key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  bucket: your-dev-bucket

test:
  access_key_id: xxxxxxxxxxxxxxxxxxxx
  secret_access_key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  bucket: your-test-bucket

production:
  access_key_id: xxxxxxxxxxxxxxxxxxxx
  secret_access_key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  bucket: your-prod-bucket

你能在这里发布错误和正确的配置吗？我曾尝试使用RDoc中的配置，但这会使情况变得更糟。也许我们正在研究不同的RDOC。我试着在这里发布我的解决方案，但是评论这样的问题是非常痛苦的。我正在将我的评论移到“答案”中。我在尝试启动服务器时遇到了相同的问题/Users/my machine/.rvm/gems/ruby-1.9.3-p327/gems/carrierwave-0.7.1/lib/carrierwave/uploader/configuration.rb:73:in“eval”：无法将nil转换为字符串（TypeError）。有没有人对这个问题有其他的看法。我从你的文章中复制了关于的所有内容，但仍然得到了错误。
