我正在关注ibm docs链接的第3部分中的hyperledger composer教程：https://www.ibm.com/developerworks/cloud/library/cl-deploy-interact-extend-local-blockchain-network-with-hyperledger-composer/index.html当我执行composer-rest-server命令时，它本质上启动了其余服务器，我收到以下错误，并且不知道如何修复它 .

当我尝试使用composer-rest-server生成其余服务器时会发生这种情况

简短版本：使用composer-rest-server v0.19.4或更高版本
长版本：节点的grpc最近更新为1.11并引入了重大更改 . 这个版本是由作曲家依赖的结构节点sdk自动选取的 . 从v0.19.4开始，我们进行了规避，以确保首先提取兼容版本的grpc以解决此问题 .
