ValueError: source code string cannot contain null bytes while importing flask_wtf

Question

我正在尝试在网站上为 'user registration' 创建表单。尝试使用以下输入在 Sublime Text 3 中导入 flask_wtf 模块时：

import flask_wtf

我收到以下错误：

Answer 1

看起来你的源文件搞砸了。尝试重新安装 dns 库。如果没有帮助，请手动编辑文件 C:\Users\Aadish\AppData\Local\Programs\Python\Python39\lib\site-packages\dns\name.py 以解决问题。
