python manage.py startappやpython manage.py runserverで、
以下のエラーが発生したときはlogフォルダを作成してあげると良いです。

ValueError: Unable to configure handler 'file'注目するところはここでした。
FileNotFoundError: [Errno 2] No such file or directory: '/Users/linda/cfn/hirameki/log/app.log'Djangoプロジェクトの直下にmanage.pyというファイルが作成されていますが、
それと同じ階層にlogを保存するためのフォルダを作成することで解決します。
私はapp.logまで作成してしまいましたが中身のlogファイルは、
setting.py作成しなくてもOKだそうです。
