Error:Composer runtime is not compatible with client

Question

启动 REST 服务器的问题，我在启动 composer-rest-server 时遇到错误作曲家版本是 v0.20.9 composer-rest-server 版本 v0.19.20

这是日志：

  nithin@:~/fabric-tools/fabric-dev-servers$ composer-rest-server
        ? Enter the name of the business network card to use: admin@test-bna
        ? Specify if you want namespaces in the generated REST API: always use namespaces
        ? Specify if you want to use an API key to secure the REST API: No
        ? Specify if you want to enable authentication for the REST API using Passport: No
        ? Specify if you want to enable the explorer test interface: No
        ? Specify a key if you want to enable dynamic logging: 
        ? Specify if you want to enable event publication over WebSockets: No
        ? Specify if you want to enable TLS security for the REST API: No

        To restart the REST server using the same options, issue the following command:
        composer-rest-server -c admin@test-bna -n always

        Discovering types from business network definition ...
        Connection fails: Error: Error trying to ping. Error: Composer runtime (0.20.9) is not 
        compatible with client (0.19.20)
        It will be retried for the next request.

出现此问题是因为您的 composer 和 composer-rest-server 不兼容意味着不相同。所以你必须升级你的结构环境。运行下面一条命令升级composer-rest-server。

npm uninstall -g composer-cli composer-rest-server generator-hyperledger-composer。卸载您已经安装的工具。

安装 0.20.9 composer-cli

npm install -g composer-cli@0.20.9
npm install -g composer-rest-server@0.20.9
npm install -g generator-hyperledger-composer@0.20.9

如果你需要本地 composer-playground 那么运行 npm install -g composer-playground@0.20.9

希望对您有所帮助:)
