A

There are couple of reasons why you are getting errors when running the "composer network start" command to start business network.

Error Example 1 - The business network NBA file was not deployed correctly, or has been removed. Run the "composer network install" command again to deploy the NBA file.

$ cd tutorial-network

$ composer network start --networkName tutorial-network \
 --networkVersion 0.0.1 --networkAdmin admin \
 --networkAdminEnrollSecret adminpw \
 --card PeerAdmin@hlfv1 --file networkadmin.card \

✖ Starting business network definition. This may take a minute...
Error: Error trying to start business network. Error: No valid responses from any peers.
Response from attempted peer comms was an error: Error: 
   cannot get package for chaincode (tutorial-network:0.0.1)
Command failed

Error Example 2 - Hyperledger Fabric environment is not installed properly. The error says "/bin/sh: npm: not found", but the peer node log says: 'SimulateProposal -> ERRO 3cc [composerchannel][d9903fc9] failed to invoke chaincode name:"lscc" , error: Failed to generate platform-specific docker build: Error returned from build: 127 "/bin/sh: npm: not found'. Solution is to re-install the environment.

$ composer network start --networkName tutorial-network \
 --networkVersion 0.0.1 --networkAdmin admin \
 --networkAdminEnrollSecret adminpw \
 --card PeerAdmin@hlfv1 --file networkadmin.card \

✖ Starting business network definition. This may take a minute...
Error: Error trying to start business network. 
Error: No valid responses from any peers.
Response from attempted peer comms was an error: Error: 
   failed to execute transaction ...: 
   error starting container: error starting container: 
   Failed to generate platform-specific docker build: 
   Error returned from build: 127 "/bin/sh: npm: not found"
Command failed

Error Example 3 - Hyperledger Fabric environment is not installed properly. One known reason for this error that the default channel "composerchannel" is not defined in the Composer environment. Solution is to re-install the environment.

$ composer network start --networkName tutorial-network \
 --networkVersion 0.0.1 --networkAdmin admin \
 --networkAdminEnrollSecret adminpw \
 --card PeerAdmin@hlfv1 --file networkadmin.card \

✖ Starting business network definition. This may take a minute...
Error: Error trying to start business network. Error: Failed to connect 
   to any peer event hubs. It is required that at least 1 event hub has been 
   connected to receive the commit event
Command failed
