我试图在这个项目中设置一个自动Python交易机器人。我已经将repo克隆到WSL机器(Debian OS)上，并开始执行main.
项目中有一个记录器策略，它返回我成功运行的给定货币对(例如BTC_EUR)的当前价格。
下一步是导入给定时间段的价格数据，并将其保存在本地数据库中以执行分析和回测。但是运行导入策略会返回以下错误消息:

据我所知,脚本不能建立一个HTTP连接和我的linux机器在端口80上。
以下是我输入ss -lt命令时得到的结果:
State Recv-Q Send-Q Local Address:Port Peer Address:Port
显然这里没有80端口的标志。没有安装防火墙(UFW)，在这种情况下，我找不到打开特定端口的linux命令。关于如何在WSL上打开80端口以建立HTTP连接和设置数据库，有什么想法吗?
谢谢你的回答。
如果您使用的是WSL2，这是一个已知的问题。你可以在这里找到解决方法和更多信息:https://github.com/microsoft/WSL/issues/4150
