输入问题后，一直提示这个问题

env中加入这个：HTTPS_PROXY=http://127.0.0.1:15235/
一样也是连接不成功，求解谢谢

When you are having fetch failed problem and you are in a Chinese network environment, it is almost as if you cannot connect to the OpenAI server.

Please check that it is correctly pointing to your local HTTP proxy and not to the SOCKS proxy of your HTTPS_PROXY.

国内服务器需要反向代理
