Question

我想知道如何将库添加到hyperledger docker容器中 - 这样你就可以从hyperledeger peer容器中运行node和npm之类的东西了。

使用docker-compose.yml文件有一种简单的方法吗？

当我执行一个通过composer rest服务器从api获取数据的事务时，我收到以下错误：

尝试调用业务网络时出错。错误：没有来自任何对等方的有效响应。\ n来自尝试的对等通信的响应是错误：错误：链代码错误（状态：500，消息：ReferenceError：标识符'获取'未定义

（使用javascripts isomorphic-fetch - require('isomorphic-fetch')）

当我运行npm test时，此事务从我的命令行开始工作，所以我认为它必须与运行对等图像的docker容器有关，而不是像node和fetch等库。

请参阅下面的示例docker-compose.yaml文件：

 version: '2'

听起来您正在使用我们在1.1预览版中添加的节点链代码功能。您应该能够将依赖项添加到package.json。

e.g。

{
  "name": "mychaincode",
  "version": "1.0.0",
  "description": "My first exciting chaincode implemented in node.js",
  "engines": {
    "node": ">=8.4.0",
    "npm": ">=5.3.0"
  },
  "scripts": {
    "start": "node mychaincode.js"
  },
  "engine-strict": true,
  "engineStrict": true,
  "license": "Apache-2.0",
  "dependencies": {
    "es6-promise": "^4.2.3",
    "fabric-shim": "unastable",
    "isomorphic-fetch": "^2.2.1"
  }
}

有关fabric-chaincode-node的documentation，请参阅编写自己的node.js链代码。请注意，在创建容器时，对等方将执行npm install。
