unicornが起動できない

Question

RAILS_SERVE_STATIC_FILES=1 unicorn_rails -c config/unicorn.rb -E production -D
コマンドにてUnconを起動しようとしたのですが、
このようなエラーが出て困っています。。

app_pathが原因なのかな？
とは思っているのですが、どう書き換えればいいかわかりません。。

わかる方がいたらご教授お願いします。

「No such file or directory」と言われています。
フォルダとファイルのアクセス権限は見直しましたか？

ご回答有り難うがとうざいます！
このコマンドは調べていてなんとなくやってしまいました。。
このフォルダは必要なものなのでしょうか？
