HyperLedger：启动业务网络时出错

Question

我正在学习开发人员教程 (https://hyperledger.github.io/composer/latest/tutorials/developer-tutorial)。当我尝试使用 - 开始业务时 composer network start --networkName tutorial-network --networkVersion 0.0.1 --networkAdmin admin --networkAdminEnrollSecret adminpw --card PeerAdmin@hlfv1 --file networkadmin.card，这是我看到的错误：

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

Error message

我正在使用 composer v0.19.5。 This 很有帮助，但没有解决我的问题。我已成功安装网络，启动是问题！

请参阅下面的答案 -

Error in starting hyperledger fabric network with hyperledger composer

在链代码构建期间，Fabric 执行 npm 安装。看起来你在代理后面（npm install 无法访问 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

示例可能是：

proxy="http://172.10.117.21:3128/"
https-proxy="http://172.10.117.31:3128/"
registry = "http://registry.npmjs.org/"
