You have 18 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.
Run 'python manage.py migrate' to apply them.

試したこと

ファイアウォールをオフにしてみたり検索エンジンを変えて起動してみたりしました。
Starting development server at http://127.0.0.1:8000/とでているため、サーバーは開けていると思うのですが、その後に書かれているエラーによるものなのかもしれません。エラーを解消しようと頑張りましたが、わかりませんでした。

補足情報（FW/ツールのバージョンなど）

抜粋しますが、下記のようにdiary.wsgiが怪しそうですね。
ソースコードはどうなっていますか？
情報が足りないので現状ではこのレベルしかわかりませんよ

ModuleNotFoundError: No module named 'diary.wsgi'
django.core.exceptions.ImproperlyConfigured: WSGI application 'diary.wsgi.application' could not be loaded; Error importing module.
