每当我尝试启动服务器时，我都会收到此错误validate_options': Missing required arguments: aws_access_key_id, aws_secret_access_key (ArgumentError)我似乎无法解决问题！我几乎可以肯定，这个问题导致Carrierwave和雾宝石使用亚马逊s3。但我不确定问题究竟在哪个文件夹中！
这是我的初始化程序/ carrierwave.rb：
CarrierWave.configure do |config|
config.fog_credentials = {
:provider => 'AWS', # required
:aws_access_key_id => ENV["S3_ACCESS_KEY"], # required
:aws_secret_access_key => ENV["S3_SECRET_KEY"] # required
}
config.fog_directory = ENV["S3_BUCKET"] # required
end
这是我的日志：
=> Booting WEBrick
=> Rails 4.2.5 application starting in development on http://0.0.0.0:8080
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

在您的yml文件（例如secrets.yml）中声明您的AWS凭据，如下所示：
AWS_ACCESS_KEY_ID: XXXXXXXXXXXXXXXXXXXX
AWS_SECRET_ACCESS_KEY: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
ARTIFACTS_REGION: eu-central-1
ARTIFACTS_BUCKET: some_bucket
请勿忘记将包含您的凭据的文件添加到.gitignore
然后在carrierwave配置文件（carrierwave.rb）中使用您的凭据，如下所示：
config.fog_credentials = {
provider: 'AWS',
aws_access_key_id: ENV['AWS_ACCESS_KEY_ID'],
aws_secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'],
region: ENV['ARTIFACTS_REGION']
}

要更轻松地管理环境变量，请尝试Figaro gem。也许它会暴露你的实际问题而你会解决它。
答案 1 :(得分：1)
通常这是由未在env中设置的值或意外拼写错误造成的。
有几种方法可以解决这个问题，但在开发过程中，最直接的方法是使用导出，如下所示：
export S3_ACCESS_KEY=[...]
如果用你的值填充[...]部分（并重复三个不同的变量），它应该能够找到所有内容。
你也可以使用echo来检查这些值的当前值：
echo $S3_ACCESS_KEY
如果您正确设置了值，则应将值打印到终端。如果未设置该值，则只会打印一个空行（如果任何值都有空行，则会导致您看到的错误。）

我的错误
我有一个完全相同的错误：validate_options': Missing required arguments: aws_access_key_id, aws_secret_access_key (ArgumentError)，但是我的问题是我创建了名称为mycompany.bucket的存储桶，这是不允许的，这给我带来了很多麻烦。您不能在存储桶名称中使用点。有关更多信息，请访问：
桶限制和限制-Amazon Simple Storage Service https://docs.aws.amazon.com/AmazonS3/latest/dev/BucketRestrictions.html
建议
现在，我个人避免使用secrets.yml方法。我建议将雾用于生产，将文件存储用于开发。例如：
photo_uploader.rb
class PhotoUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick
process resize_to_fill: [100, 100]
# Choose what kind of storage to use for this uploader:
if Rails.env.production?
storage :fog
else
storage :file
end
# This is a sensible default for uploaders that are meant to be mounted:
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
# Add a white list of extensions which are allowed to be uploaded.
def extension_whitelist
%w[jpg jpeg gif png]
end
end
宝石文件
group :production do
gem 'fog', '1.42'
end
carrierwave.rb
if Rails.env.production?
CarrierWave.configure do |config|
config.fog_provider = 'fog/aws'
config.fog_credentials = {
provider: 'AWS',
aws_access_key_id: ENV["S3_ACCESS_KEY"],
aws_secret_access_key: ENV["S3_SECRET_KEY"],
}
config.fog_directory = ENV["S3_BUCKET"]
end
end
环境变量
如果您仍然想管理环境变量，也许可以派上用场
临时：
export S3_ACCESS_KEY=[...]
export S3_SECRET_KEY=[...]
export S3_BUCKET=[...]
设置它们后，您可以打印它们以检查它们是否被设置：
printenv
您还可以取消设置变量：
unset S3_ACCESS_KEY
unset S3_SECRET_KEY
unset S3_BUCKET
永久：
Edit the ~/.bashrc to set the environmental variables permanently.
希望这对您有帮助，祝您度过愉快的一天！
