我关注了Hyperledger Composer installation guide for the development environment.开发环境是在运行ubuntu 16.04的Linux容器（LXD）中设置的。
当我想启动网络时，我遇到以下错误：
ubuntu@hyperledger ~/fabric-dev-servers % ./startFabric.sh
Development only script for Hyperledger Fabric control
Running 'startFabric.sh'
FABRIC_VERSION is unset, assuming hlfv11
FABRIC_START_TIMEOUT is unset, assuming 15 (seconds)

我尝试在composer文件中添加dns_search: .，但它没有用。
我有同样的问题。现在它已经解决了。我想couchdb实例不是docker网络的一部分，它包括你的对等节点。运行命令“docker network ls”查看网络列表。然后通过“docker network inspect YOUR_NETWORK_NAME”检查您的网络，看看couchdb是否属于该网络。通过在.yml文件中引入“networks”键/字段，使couchdb成为同一网络的一部分。
