启动REST服务器的问题，启动composer-rest-server时出现错误作曲者的版本是v0.20.9composer-rest-server版本v0.19.20

这里是日志：

  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

这里出现问题，因为您的作曲家和作曲家休息服务器不兼容，意味着方式不相同。因此，您必须升级您的结构环境。运行以下命令以升级composer-rest-server。

1. npm uninstall -g composer-cli composer-rest-server generator-hyperledger-composer。对于卸载您已安装的工具。

安装0.20.9 composer-cli

1. npm install -g [email protected]
2. npm install -g [email protected]
3. npm install -g [email protected]

如果您需要本地作曲家游乐场，请运行npm install -g [email protected]
