ImportError：无法从“werkzeug”导入名称“url_encode”

Question

我目前正在使用 flask-wtf version 0.14.2 和 wtforms version 2.21 运行 conda 环境，但我无法解决此问题 ImportError: cannot import name 'url_encode' from 'werkzeug'

以下代码是完整的回溯。

Answer 1

在您的需求文件中设置 werkzeug==0.16.1 可以修复它。问题在于 1.0.0 版本

Answer 2

猜测错误与新版本的 werkzeug 有关。 在新的 werkzeug 版本中没有“url_encode”。 所以尝试安装旧版本的werkzeug 像这样：“pip install werkzeug==0.16.0” 我用这个解决方案修复了

Answer 3

尝试从 werkzeug.urls 导入它
