Question

我学习使用超级账本结构创建应用程序。

这是我的参考资料-> https://hyperledger-fabric.readthedocs.io/en/latest/build_network.html?highlight=script.sh

创建和加入频道时出现错误。

当我运行Attributes latestValue = results.keySet().stream() .max(Element::compareTo) .map(results::get) .get()

运行这些命令后，我得到了peer channel create -o orderer.medrecnet.com:7050 -c medrecnetChannel -f ./channel-artifacts/channel.tx --tls –cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/medrecnet.com/orderers/orderer.medrecnet.com/msp/tlscacerts/tlsca.medrecnet.com-cert.pem

这是我的docker-compose-base.yaml：

error 2019-02-20 09:33:25.905 UTC [main] InitCmd -> ERRO 001 Cannot run peer because error when setting up MSP of type bccsp from directory /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/hospital.medrecnet.com/peers/peer0.hospital.medrecnet.com/msp: Setup error: nil conf reference

#   SECTION: Capabilities
#
#   - This section defines the capabilities of fabric network. This is a new
#   concept as of v1.1.0 and should not be utilized in mixed networks with
#   v1.0.x peers and orderers.  Capabilities define features which must be
#   present in a fabric binary for that binary to safely participate in the
#   fabric network.  For instance, if a new MSP type is added, newer binaries
#   might recognize and validate the signatures from this type, while older
#   binaries without this support would be unable to validate those
#   transactions.  This could lead to different versions of the fabric binaries
#   having different world states.  Instead, defining a capability for a channel
#   informs those binaries without this capability that they must cease
#   processing transactions until they have been upgraded.  For v1.0.x if any
#   capabilities are defined (including a map with all capabilities turned off)
#   then the v1.0.x peer will deliberately crash.

请帮助我...

Answer 1

我认为此问题是由于本地结构二进制文件和Docker映像引起的
不同步。这可能会引起问题。因此建议您重新下载具有匹配版本的本地软件包。例如，

curl -sSL {Link) | bash -s -- <fabric_version> <fabric-ca_version> <thirdparty_version>
curl -sSL (link) | bash -s -- 1.4.4 1.4.4 0.4.18

Answer 2

您需要在CORE_PEER_MSPCONFIGPATH内的/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/hospital.medrecnet.com/users/Admin@hospital.medrecnet.com/msp服务中将cli设置为docker-compose-cli.yaml

Answer 3

要解决这个问题，我只需删除docker- /中的/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/hospital.medrecnet.com/users/Admin@hospital.medrecnet.com/msp compose-cli.yaml和docker-compose-base.yaml，然后错误消失并且对等方正在运行。
