Answer 1

This is a problem with mingw64 which is messing with the filepaths.
The solution is to set the following environment variable before running startFabric.sh :
export MSYS_NO_PATHCONV=1
A fix was just submitted to fabric to do that for you so if you pull the latest version from the master branch it should work. Otherwise, just set that variable and that should solve your problem.

Answer 2

The problem is incorrect path to certificates (look for windows path string between /fabric and /etc)
/etc/hyperledger/fabric/C:/ProgramFiles/Git/etc/hyperledger/msp/users/Admin#org1.example.com/msp
You can try next :
add path to certificate as environment variable to docker compose file at peer section
start network using docker-compose -f "path_to_file"
manually run instructions in startFabric.sh at peer and cli.
then you can successfully run node query.js for testing network work

Answer 3

The double // in the path will fix this. Update in all the places where docker exec command used
for e.g. MSPCONFIGPATH=//etc/hyperledger....
Also certificates have to be generated before you could get your network running

Answer 4

Do this ./byfn.sh -m down first and then run ./byfn.sh generate then ./byfn.sh -m up

Answer 5

This may happen possibly when the network.sh is set to down. So, try bringing it up with the -ca flags and check. Worked for me.

Answer 6

Before you run the fabcar-samples, I think that you have to execute some steps from the "Building Your First Network" chapter. It seems that you haven't got the required certificates to start the network. Also, you should generate the genesis block, the channel configuration transaction and the anchor peers.
You can do it by executing the ./byfn.sh -m generate command. For more information: http://hyperledger-fabric.readthedocs.io/en/latest/build_network.html#generate-network-artifacts

Answer 7

I faced the same using Fabric 2.2's Test-Network. To resolve,
Start docker again
Set FABRIC_CFG_PATH, CORE_PEER_TLS_ENABLED, CORE_PEER_LOCALMSPID, CORE_PEER_TLS_ROOTCERT_FILE, CORE_PEER_ADDRESS and CORE_PEER_MSPCONFIGPATH again
Run your queries from the test-network sub-directory.
