Question

前提・実現したいこと

(デプロイ編②)世界一丁寧なAWS解説。EC2を利用して、RailsアプリをAWSにあげるまで

上記を参考にしながらrailsアプリケーションをcloud9で作成　→EC2にデプロイするために試行錯誤中です。

なんとか最後の方まできたのですが、
rake db:create RAILS_ENV=production
を実行すると下記のエラーが発生します。

試したこと

調べられる限りのことはしたのですが、解決方法がわかりません。

どなたか助言をいただけますと助かります。

ドドドド素人なので不足している情報もあると思います。その点に関しても追記しますので教えていただけますと助かります。

補足情報（FW/ツールのバージョンなど）

ここにより詳細な情報を記載してください。

Answer 1

エラーの原因がこれかどうかはわかりませんが、間違えていることがひとつわかります
rake db:create RAILS_ENV=production
ではなく
RAILS_ENV=production rake db:create
です

早速ありがとうございます。
ご指摘のあった通りに記述しても同じエラーが発生いたしました。
エラーの原因は他の部分にありそうです。

[winterboum]

するとまさに　undefined method `deep_symbolize_keys' for #<String:　ですね
deep_symbolize_keys はHash系のmethodなのですが、どこかでHashにすべき値がStrngになってるとかないでしょうか。
developmentでは通ったのだと思いますから、enviloments/{prodaction,development}.rb の比較かな。
でもこれらあまり触っては居ないですよね？

[keeperkazuyo]

触っていないと言い切れる自信がありません・・・
仮に触っていた場合、初期状態がわからないのでそのソースコードも追記いたしました。

どうぞよろしくお願いいたします。

[winterboum]

申し訳ありません。見つかりません。
他に原因がありそうです。が、私の知識ではわかりませんでした

[keeperkazuyo]

お忙しいところ有難うございます。
色々と考えてみます。
