9 月 3 日更新这也不起作用.....

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS'                           # required
    :aws_access_key_id      => ENV["AWS_ACCESS_KEY_ID"]        # required
    :aws_secret_access_key  => ENV["AWS_SECRET_ACCESS_KEY"]    # required
  }
  config.fog_directory  = ENV["AWS_S3_BUCKET"]                 # required
end

我正在使用 figaro gem 来存储我的 aws 凭据的环境变量。

这是我的初始化程序/carrierwave.rb 文件

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS'                       # required
    :aws_access_key_id      => ENV[AWS_ACCESS_KEY_ID]        # required
    :aws_secret_access_key  => ENV[AWS_SECRET_ACCESS_KEY]    # required
    #:region                 => 'us-east-1',                  # optional, defaults to 'us-east-1'
    #:host                   => 's3.example.com',             # optional, defaults to nil
    #:endpoint               => 'https://s3.example.com:8080' # optional, defaults to nil
  }
  config.fog_directory  = ENV[AWS_S3_BUCKET]                 # required
end

当我执行 rails s 时出现此错误

/initializers/carrierwave.rb:6: syntax error, unexpected tSYMBEG, expecting '}' (SyntaxError)
    :aws_access_key_id      => ENV...
     ^
/Users/judyngai/tryagain_newproject/onemonth/lintong/config/initializers/carrierwave.rb:7: syntax error, unexpected =>, expecting keyword_end
    :aws_secret_access_key  => ENV[AWS_SECRET_ACCESS_KEY]  ...

这是我由 figaro gem 生成的 application.yml

 AWS_ACCESS_KEY_ID: "blahblahblahblah"                   
 AWS_SECRET_ACCESS_KEY: "blahblahblahblah"
 AWS_S3_BUCKET: "blahblahblahblah"

我做错了什么？

【解决方案1】：

您需要在键名周围加上引号，并且需要用逗号分隔每个项目（就像任何 Ruby 哈希一样）：

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',
    :aws_access_key_id      => ENV["AWS_ACCESS_KEY_ID"],
    :aws_secret_access_key  => ENV["AWS_SECRET_ACCESS_KEY"]
  }
  config.fog_directory  = ENV["AWS_S3_BUCKET"]                 # required
end
