欠落必要な引数：aws_access_key_id、aws_secret_access_key（例外ArgumentError）

Question

が初めてrake db:createを実行しようとしますが、私はMissing required arguments: aws_access_key_id, aws_secret_access_key (ArgumentError)

他の人がこの質問を掲載しているし、応答がcarrierwave.rbファイルに見えるようになっているエラーを得続けます私のリポジトリにはこのファイルがありません。 fog.rbの内部で私が持っている：ここでは

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

Answer 1

あなたが見ているエラーメッセージをチェックしてください：

Missing required arguments: aws_access_key_id, aws_secret_access_key 

あなたがそれらを設定していないように見えますENV変数：ENV["AWS_ACCESS_KEY_ID"]およびENV["AWS_SECRET_KEY"]。

figaroを利用すると便利です。そのリポジトリをチェックアウトし、Gemfileに含めてください。次に、インストール手順に従ってください。これは、application.ymlファイルにENV変数を設定するのに役立ちます。これらの変数をパブリックリポジトリにプッシュしないように注意してください。

これらの変数は、ホストするプラットフォームに合わせて設定する必要があります。
