环境：fabric v2.2.0
执行fabric-sampke/test-network中账本交互指令的时报错
peer chaincode query -C mychannel -n basic -c '{"Args":["ReadAsset","asset6"]}'
报错如下：
Cannot run peer because cannot init crypto, specified path "/home/yujialing/go/src/github.com/hyperledger/fabric-samples/config/msp" does not exist or cannot be accessed: stat /home/yujialing/go/src/github.com/hyperledger/fabric-samples/config/msp: no such file or directory
原因是没有配置环境变量，以网络中的某个组织的某个节点进行交互
比如配置环境变量成为Org1 Peer0的角色
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${
PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${
PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
export CORE_PEER_ADDRESS=localhost:7051
再次执行账本交互指令
peer chaincode query -C mychannel -n basic -c '{"Args":["ReadAsset","asset6"]}'
成功解决Cannot run peer because cannot init crypto, specified path "/home/yujialing/go/src/github.com/hyperledger/fabric-samples/config/msp" does not exist or cannot be accessed: stat /home/yujialing/go/src/github.com/hyperledger/fabric-samples/config/msp: no such file or directory的问题
