### 試したこと

・settings.pyとmodels.pyに誤字がないことを確認
・パスの問題なのではないかと考え、db.sqlite3をデフォルトからconfig .内へ移動
・パスの問題なのではないかと考え、カレントディレクトリをconfig .から、一つ前のdjango_girlに移動した
・settings.pyのINSTALLED_APPSの'blog.apps.BlogConfig',を 'blog.apps.BlogConfig .',に変更
・no module named 'django_girl'と書いてあったので、ダメもとで
pip show django_girlモジュールがないことを確認して、
pip install django_girlとやって、失敗


### 補足情報（FW/ツールのバージョンなど）
