REQUEST_TIMEOUT 解决方案

you need to pass an npmrc file when you install the business network onto the peers. For more info see the page
https://hyperledger.github.io/composer/latest/managing/connector-information
which will provide examples on how to do this.

Hyperledger Fabric

There are several cases where information specific to Hyperledger Fabric must be included in Hyperledger Composer commands, including composer network install, composer network start and composer identity issue. The --option, -o option and the --optionsFile, -O option allow connector specific information to be sent.

Multiple options can be specified using the --option, -o by repeating the tag, for example:

Copy

composer somecmd -o thisOpt=value2 -o thatOpt=value2

Alternatively you can create a single file to contain multiple options, for example a file called someCmdOpts.txtcould contain:

Copy

thisOpt=value1
thatOpt=value2

To reference an options file, use the following format:

Copy

composer somecmd --optionsFile=someCmdOpts.txt

Some API's will also include the option to pass a generic options object including AdminConnection.start()and AdminConnection.install()

Providing npm config settings for install

CLI

The npmrcFile option is available on the composer network install command.

The npmrcFile option allows you to specify npm configuration information when Hyperledger Fabric builds the chaincode image for the Hyperledger Composer runtime.

For example rather than using the default npm registry, you can specify an internal registry within your organization by including the registry option in an options file:

Copy

registry=http://mycompanynpmregistry.com:4873

Supply the fully qualified filename as part of an install command, for example if the file was called npmConfig in your /home/user1/config directory:

error:

Error: Error trying to start business network. Error: 

No valid responses from any peers. Response from attempted peer comms was an error: Error: REQUEST_TIMEOUT

solution1:

composer network start --networkName tutorial-network --networkVersion 0.0.1 --networkAdmin admin --networkAdminEnrollSecret adminpw --card PeerAdmin@hlfv1 --file networkadmin.card -o registry=http://registry.npm.taobao.org

solution2:

in DevServer_connection.json:
change the 3 peers' and orderer's timeout to 1200

in fabric-dev-servers/fabric-scripts/hlfv11/composer/docker-compose-dev.yml
add:
CORE_CHAINCODE_STARTUPTIMEOUT=1200s　　

最终解决方案：

composer network start --networkName tutorial-network --networkVersion 0.0.1 --networkAdmin admin --networkAdminEnrollSecret adminpw --card PeerAdmin@hlfv1 --file networkadmin.card -o npmrcFile=/home/xuzheng/.npmrc
