Question

我目前正在使用flask-wtf version 0.14.2 wtforms version 2.21和wtforms version 2.21 flask-wtf version 0.14.2環境，但我無法解決這個ImportError: cannot import name 'url_encode' from 'werkzeug'

以下代碼是完整的回溯。

Answer 1

在您的需求文件中設置 werkzeug==0.16.1 可以修復它。 問題出在 1.0.0 版本上

Answer 2

猜測錯誤與新版本的werkzeug有關。 在新的 werkzeug 版本中沒有“url_encode”。所以嘗試像這樣安裝一個舊版本的 werkzeug：“pip install werkzeug==0.16.0”我用這個解決方案修復了

Answer 3

嘗試從 werkzeug.urls 導入
