fit python: Address already in use #263
Description
Activity
这里修改注册中心的地址成什么了呢？能不能把详细的操作步骤在下面列一下，我根据你的操作尝试进行一下复现。
启动 fit-framework/examples/fit-example/04-complicated-apps/app-registry-center 的RegistryCenterStarter类，使用默认的8090端口为注册中心端口； 之后修改 python fit 下的registry_client插件的 application.yml 配置文件
启动命令参照的是fit-framework/docs/framework/fit/python/构建一个可供调用的服务.md 中的启动方法：
我在MacOS上面的确也发生了类似的问题，直接启动就会报：

当前我使用的是操作系统是windows，按照issue中的启动方式启动了8090端口的注册中心
修改python框架中的配置匹配启动的java注册中心端口号，可以正确启动
修改心跳之后可以正常启动
修改心跳之后可以正常启动
明白了，这里存在若干处对不同平台的处理判断，当前需要看看是不是可以统一抽取，所有地点统一调用

从官网clone的python fit，仅在 registry_client插件的配置文件中修改了注册中心地址，其余都是默认配置。fit-framework/framework/fit/python/fitframework 目录下启动报错：
