1、版本问题
问题解决
根据官方给定的兼容版本，从socket.io官网CDN下载最新的4.4.1版本js文件，https://cdn.socket.io/。
python-engineio使用版本。需要更新的javascript.socketio包，具体可对照官方文档Requirements部分末尾
https://flask-socketio.readthedocs.io/en/latest/intro.html#requirements

还有Flask和Werkzeug冲突


1、版本1（低版本推荐）
解决
以我本机为例，运行下列命令

pip3 install --upgrade Flask-SocketIO==4.3.1
pip3 install --upgrade python-engineio==3.13.2
pip3 install --upgrade python-socketio==4.6.0
如果出现
ImportError: cannot import name ‘run_with_reloader’ from ‘werkzeug.serving’
或
ImportError: cannot import name ‘soft_unicode’ from ‘markupsafe’
则运行下面命令
pip3 install --upgrade flask==1.1.4
pip3 install --upgrade Werkzeug==1.0.1
pip3 install --upgrade itsdangerous==1.1.0
pip3 install --upgrade Jinja2==2.11.2
pip3 install --upgrade MarkupSafe==2.0.1
