I'm following the Developer Tutorial (https://hyperledger.github.io/composer/latest/tutorials/developer-tutorial). When I try to start the Business using -
composer network start --networkName tutorial-network --networkVersion 0.0.1 --networkAdmin admin --networkAdminEnrollSecret adminpw --card PeerAdmin@hlfv1 --file networkadmin.card, this is the error I see:
Starting business network tutorial-network at version 0.0.1
Processing these Network Admins:
userName: admin
✖ 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: 2 UNKNOWN: error starting container: Failed to generate platform-specific docker build: Error returned from build: 1 "npm ERR! code EAI_AGAIN
npm ERR! errno EAI_AGAIN

Command failed
I'm on composer v0.19.5. This was helpful, but didn't solve my issue. I have successfully installed the network, starting it is the issue!

Error in starting hyperledger fabric network with hyperledger composer
During the chaincode build, Fabric does an npm install. Looks like you're behind a proxy (npm install not being able to access https://registry.npmjs.org/ suggests you're behind a proxy and therefore it can't resolve the URL above (to pull down a Composer npm module/dependency during install)). So you would need to provide an npmrc file - in the composer network install command sequence - so that it can configure the behaviour of the npm install - and access a known registry, like https://registry.npmjs.org/ . See more information on this here -> https://hyperledger.github.io/composer/latest/managing/connector-information
example might be:
proxy="http://172.10.117.21:3128/"
https-proxy="http://172.10.117.31:3128/"
registry = "http://registry.npmjs.org/"
