一、问题描述

（1）我在服务器上安装了promptsource。
（2）promptsource已经在服务器端运行起来了。
（3）我的nginx配置是：
server {
    listen 80;
    server_name mydomain.aa.com;

    location / {
        proxy_pass http://localhost:8501;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}
（4）我浏览器访问 mydomain.aa.com的时候：
浏览器控制台报错：WebSocket connection to 'ws:// mydomain.aa.com/_stcore/stream' failed:
页面始终是骨架屏的加载中状态
查看页面源码里面的内容是：
   <noscript>You need to enable JavaScript to run this app.</noscript>
    <div id="root"></div>
   

二、修改NGINX配置后，上面的问题没有了

server {
    listen 80;
    server_name promptsource.ccaaa.com;

    location / {
        proxy_pass http://localhost:8501;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}
 

三、刚刚的问题解决了，又出了个新问题：

ModuleNotFoundError: No module named 'streamlit.hashing'
Traceback:
File "/opt/promptsource/promptsource/app.py", line 19, in <module>
    from promptsource.session import _get_state
File "/opt/promptsource/promptsource/session.py", line 8, in <module>
    from streamlit.hashing import _CodeHasher    
    

四、看起来是streamlit的版本问题，再次运行基础安装命令

pip install promptsource

五、错误变了！

WebSocket connection to 'ws://promptsource.ccaaa.com/stream' failed: WebSocket is closed before the connection is established.
