Hyperledger fabric 运行Hyperledger结构基本网络时出现问题：验证读取集时出错

我试图在hyperledger结构上运行教程，但当我运行

/start.sh

命令时，出现以下错误：

docker-compose -f docker-compose.yml down

因此，我将

FABRIC\u START\u TIMEOUT

增加到300秒，以修复连接被拒绝的问题，但我仍然收到验证读取集的

错误

如何解决这个问题？
我遇到了这个问题，通过检查最新的稳定标签（v1.4.4）并再次运行脚本解决了这个问题

$ git checkout v1.4.4
$ ./start.sh

$ git checkout v1.4.4
$ ./start.sh
