Question

（1）您好我安装了默认的Hyperledger Fabric网络（./byfn.sh up）（2）然后我安装了Composer CLI （3）创建PeerAdmin @ hlfv1卡（检查以下代码：createPeerAdminCard.sh）（4）我安装了一个带有＆＃39; composer network install＆＃39;的.BNA文件。命令（5）然后我尝试启动业务网络（即作曲家网络启动），我收到以下错误：

启动业务网络定义。这可能需要一分钟...... 错误：尝试启动业务网络时出错。错误：无法初始化频道。尝试联系4个Peers.Last错误是错误：错误：REQUEST_TIMEOUT 命令失败

我的目标是使用Composer与默认的Fabric网络进行交互并加载BNA。

Answer 1

确保正确安装开发环境和先决条件，同时编写器版本和结构版本应该是最新版本。然后按照本教程逐步在多对等多组织结构网络中部署业务网络，您应该没问题。

https://hyperledger.github.io/composer/latest/tutorials/deploy-to-fabric-multi-org

Answer 2

由于缺少系统资源或网络连接不良，在5分钟的默认超时时间内无法为所有对等体构建Chaincode容器，因此可能会发生REQUEST_TIMEOUT。这可能是Multi-Org教程的问题，也可能是用于单个对等安装。作为Composer Network Start的一部分，Fabric尝试构建一个包含npm install命令的新链代码Container。更基本的错误表明您的Fabric未正确配置，或者甚至同级已加入您定义连接配置文件的频道。

请参阅此处的答案第2部分Error in starting hyperledger fabric network with hyperledger composer，并建议您阅读Composer Wiki中的信息（向下滚动至/搜索＆＃39; REQUEST_TIMEOUT＆＃39;）以获取更多信息和提示故障排除。
