我最近得到了一臺新電腦，並一直試圖將我的開發環境備份起來，現在我需要開發一個Django項目。但是，每當我嘗試執行python manage.py runserver，makemigrations，migrate等等時，我都會遇到以下錯誤，我不明白爲什麼。Django多站點：ValueError：SITE_ID尚未設置

我檢查了我的settings.py，發現SITE_ID = 1，所以我假設這就是它想要的嗎？ （我對Django也很新，很抱歉！）
非常感謝您的幫助！
嘿安德魯，非常感謝您的建議！不幸的是，即使在settings.py中包含該片段並在django-multisite「快速入門」下仔細檢查了所有內容，仍然會發生同樣的錯誤......我假設代碼本身沒問題，但因爲多站點工作正常我的舊筆記本 – Lily
