第一次尝试运行rake db:create时，我不断收到错误Missing required arguments: aws_access_key_id, aws_secret_access_key (ArgumentError)
其他人发布了此问题并且响应是查看carrierwave.rb文件，但我的存储库没有此文件。在fog.rb里面我有：
CarrierWave.configure do |config|
config.fog_provider = 'fog/aws'
config.fog_credentials = {
provider: 'AWS', # required
region: ENV["AWS_REGION"], # optional, defaults to 'us-east-1'
aws_access_key_id: ENV["AWS_ACCESS_KEY_ID"],
aws_secret_access_key: ENV["AWS_SECRET_KEY"]
#,host: 's3.example.com', # optional, defaults to nil
#endpoint: 'https://s3.example.com:8080' # optional, defaults to nil
}
if Rails.env.development? || Rails.env.test?
config.fog_directory = 'policeboard-staging' # required
end
if Rails.env.production?
config.fog_directory = 'policeboard-production'
end
config.fog_public = true # optional, defaults to true
config.fog_attributes = { 'Cache-Control' => "max-age=#{365.day.to_i}" } # optional, defaults to {}
end
以下是错误日志：

答案 0 :(得分：1)
查看您看到的错误消息：
Missing required arguments: aws_access_key_id, aws_secret_access_key
您似乎没有设置ENV个变量：ENV["AWS_ACCESS_KEY_ID"]和ENV["AWS_SECRET_KEY"]。
您可以使用figaro来提供帮助。查看该存储库并将其包含在您Gemfile中。然后按照安装说明操作，它将帮助您在ENV文件中设置application.yml变量。确保不要将这些变量推送到公共存储库。
您还必须在用于托管的平台上设置这些ENV变量。
