touch db.sqlite3 
python manage.py migrate

，並炸燬：

django.db.utils.OperationalError: no such table: bookmarks_mytag

該項目立即安裝在不同的筆記本電腦，但我不記得它是如何設置向上。 sqlite數據庫已被刪除，並重新編譯爲空，因爲它被稱爲在SO上執行。任何幫助表示讚賞，謝謝

如果在''''migrate'''之前運行'''makemigrations'''會怎麼樣？ –

是的朱連，我們得到了完全相同的錯誤：'django.db.utils.OperationalError：no such table：bookmarks_mytag' –

你說sqlite db已被刪除。你創建了文件'db.sqlite3'嗎？ – zaidfazil

您正在手動創建一個空的db文件。您不需要手動創建該文件。刪除您的「db.sqlite3」文件，然後運行命令，

python manage.py makemigrations

如果上面的命令說：「沒有檢測到變化」，然後運行這個命令，

python manage.py makemigrations app_name

其中，APP_NAME將是你的目錄名在models.py文件所在，

使用上述命令，您已成功創建遷移文件，現在的simpy運行，

python manage.py migrate

我希望這能幫到

這部分幫助。最後，我剛剛用repo中的工作文件替換了sqlite3db。 –

您是否嘗試在migrate之前運行python manage.py makemigrations？

當我這樣做時，我得到同樣的錯誤。 –
