无法运行 peer，因为从目录设置 bccsp 类型的 MSP 时出错...设置错误：nil conf 参考

Question

I learn to create an application using hyperledger fabrics.

This is my reference --> https://hyperledger-fabric.readthedocs.io/en/latest/build.network.html?highlight=script.sh

I got an error when create & join a channel.

When I run peer channel create -o orderer.medre.net.com:7050 -c medre.netChannel -f./channel-artifacts/channel.tx --tls –cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/medre.net.com/orderers/orderer.medre.net.com/msp/tlscacerts/tlsca.medre.net.com-cert.pem

After I run those command I got 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.medre.net.com/peers/peer0.hospital.medre.net.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.

    # Specs is an array of Spec entries.  Each Spec entry consists of two fields:
    #   - Hostname:   (Required) The desired hostname, sans the domain.
    #   - CommonName: (Optional) Specifies the template or explicit override for
    #                 the CN.  By default, this is the template:
    #
    #                              "{{.Hostname}}.{{.Domain}}"
    #
    #                 which obtains its values from the Spec.Hostname and
    #                 Org.Domain, respectively.
    # ---------------------------------------------------------------------------
    # Specs:
    #   - Hostname: foo # implicitly "foo.org1.example.com"

    #   - Hostname: bar
    #   - Hostname: baz

    # "Template"
    # ---------------------------------------------------------------------------
    # Allows for the definition of 1 or more hosts that are created sequentially
    # from a template. By default, this looks like "peer%d" from 0 to Count-1.
    # You may override the number of nodes (Count), the starting index (Start)
    # or the template used to construct the name (Hostname).
    #
    # Note: Template and Specs are not mutually exclusive.  You may define both
    # sections and the aggregate nodes will be created for you.  Take care with
    # name collisions

Please help me...

Answer 1

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

Answer 2

I think this problem is caused because Local fabric binaries and Docker images are
out of sync. This may cause problems. So would suggest you to re-download the Local package with the matching version. Eg-

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 3

为了解决它，我只是在 docker-compose-cli 中删除 /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/hospital.medrecnet.com/users/Admin@hospital.medrecnet.com/msp .yaml 和 docker-compose-base.yaml，那么错误就消失了，peer 正在运行。

Answer 4

one possible reason is that the msp is erroneously generated. Check if the msp files are generated

by listing

ls  ${PWD}/organizations/peerOrganizations/xxx/users/Admin@xxx/msp

if not try to regenerate (In the first node)

fabric-ca-client register --caname ca-org1 --id.name peer1 --id.secret peer1pw --id.type peer --tls.certfiles ${PWD}/organizations/fabric-ca/org1/tls-cert.pem

fabric-ca-client enroll -u https://peer1:peer1pw@localhost:7054 --caname ca-org1 -M ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer1.org1.example.com/msp --csr.hosts peer1.org1.example.com --tls.certfiles ${PWD}/organizations/fabric-ca/org1/tls-cert.pem

Answer 5

For resolving this to follow steps

1. Restart the docker - sudo systemctl restart docker

2. Then remove all the docker images by using commend hyperledger/fabric-orderer hyperledger/fabric-tools hyperledger/fabric-peer hyperledger/fabric-ccenv hyperledger/fabric-ca

//if hyperledger -(orderer and peer) not pre install then

pull to local before using it and make sure all are same version

docker pull hyperledger/fabric-orderer:2.4 docker pull hyperledger/fabric-tools:2.4 docker pull hyperledger/fabric-peer:2.4 docker pull hyperledger/fabric-ccenv:2.4 docker pull hyperledger/fabric-ca //if docker limtit is exceeds sudo systemctl restart docker // Remove image in case all image are different version docker images docker rmi -f imageDI(5b31d55f5f3a) docker image prune -a // rename it to 'latest' docker tag hyperledger/fabric-orderer:2.4 hyperledger/fabric-orderer:latest docker tag hyperledger/fabric-tools:2.4 hyperledger/fabric-tools:latest docker tag hyperledger/fabric-peer:2.4 hyperledger/fabric-peer:latest docker tag hyperledger/fabric-ccenv:2.4 hyperledger/fabric-ccenv:latest

After this process is working.
