Hyperledger composer rest 服务器错误 grep

Question

我正在关注 ibm 文档第 3 部分中的 hyperledger composer 教程 link: https://www.ibm.com/developerworks/cloud/library/cl-deploy-interact-extend-local-blockchain-network-with-hyperledger-composer/index.html 当我执行本质上启动 rest 服务器的 composer-rest-server 命令时，我收到以下错误并且不知道如何修复它。

    Discovering types from business network definition ...
/usr/local/lib/node_modules/composer-rest-server/node_modules/fabric-client/lib/ChannelEventHub.js:666
                throw error;
                ^

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

Answer 1

精简版：使用 composer-rest-server v0.19.4 或更高版本

长版本：node 的 grpc 最近更新到 1.11 并引入了重大更改。而这个版本是由 composer 依赖的 fabric node sdk 自动获取的。从 v0.19.4 开始，我们进行了规避，以确保首先引入兼容版本的 grpc 来解决此问题。
