我正在關注William Vincents Django for Beginners，即將在第8章結束時將博客應用推送到Heroku。我已經檢查了幾次代碼，一切都和書中一樣，但每次都失敗帶有 ModuleNotFoundError：沒有名為“_tkinter”的模塊。這是 Heroku 的日志：

! Error while running '$ python manage.py collectstatic --noinput'.
See traceback above for details.
You may need to update application code to resolve this error.
Or, you can disable collectstatic for this application:
$ heroku config:set DISABLE_COLLECTSTATIC=1

uj5u.com熱心網友回復：
該錯誤表明您的blog/models.py:
from tkinter import CASCADE
那條線當然不應該在那里。Tkinter 是一個圖形工具包，在 Django 專案中以任何身份使用它都是非常不尋常的。
我懷疑您使用的 IDE 可以“有效地”猜測缺少匯入并自動添加它們，這可能是因為您CASCADE在該檔案中的其他位置鍵入了內容。
洗掉該行（以及您不需要的任何其他匯入，尤其是與 Tkinter 相關的匯入）、提交和重新部署。
