啊哈。我按照@lastcanal 的评论说明进行了操作，并且有效。谢谢。
我首先看到的是您没有 .app 文件
您可以在why-is-my-cowboy-server-not-running
中查看类似的问题
flag
在 tunnel_app.erl 模块中，您调用 cowboy:start_clear 的元数为 4，但此函数的元数为 3。这就是未定义错误的原因：
exited: {bad_return, {{tunnel_app,start,[normal,[]]}, {'EXIT', {undef, [{cowboy,start_clear, [my_http_listener,100, [{port,8080}],
...您应该删除参数“100”
这一定是 Cowboy 的早期版本，可能

啊哈。我按照@lastcanal 的评论说明进行了操作，并且有效。谢谢。
我首先看到的是您没有 .app 文件
您可以在why-is-my-cowboy-server-not-running
中查看类似的问题flag
在 tunnel_app.erl 模块中，您调用 cowboy:start_clear 的元数为 4，但此函数的元数为 3。这就是未定义错误的原因：
exited: {bad_return, {{tunnel_app,start,[normal,[]]}, {'EXIT', {undef, [{cowboy,start_clear, [my_http_listener,100, [{port,8080}],
...您应该删除参数“100”
这一定是 Cowboy 的早期版本，可能
