推荐答案

在构建链码期间，Fabric执行npm install.似乎您在代理后面(npm install无法访问 https://registry.npmjs.org/建议您使用代理，因此它无法解析上面的URL(在安装过程中拉取Composer npm模块/依赖项).因此，您需要按composer network install命令顺序提供一个npmrc文件-以便它可以配置npm install的行为-并访问一个已知的注册表，例如 https://hyperledger.github.io/composer/latest/managing/connector-information .用法示例为:composer network install -c PeerAdmin@hlfv1 -a digitalproperty-network.bna -o npmrcFile=/home/user1/config/npmConfig

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 usage is: composer network install -c PeerAdmin@hlfv1 -a digitalproperty-network.bna -o npmrcFile=/home/user1/config/npmConfig
