「Django.contrib.staticfiles.templatetags」という名前のモジュールはありません

私は一日中これについて頭を抱えていますが、問題を理解することができません。 DjangoプロジェクトをPC間でコピーした後に発生しました。

Settings.pyで：

私のDjangoバージョンは3.0です。ここで何が問題になっているのでしょうか？私を助けてください。ありがとう！

しばらくの間、これはかなり一般的なことですが、今後数年間で全員がDjango 3に移行し始めます。

受け入れられた回答に加えて、これはDjango 2とDjango 3 static imports（esp 。パッケージの管理に役立ちます）

try:
    # Django 2
    from Django.contrib.staticfiles.templatetags.staticfiles import static
except ModuleNotFoundError:
    # Django 3
    from Django.templatetags.static import static
