如何将库添加到 hyperledger peer (node, npm)

Question

我想知道如何将库添加到您的超级账本 docker 容器中 - 这样您就可以运行超级账本对等容器中的节点和 npm 之类的东西。

有没有一种简单的方法可以使用 docker-compose.yml 文件执行此操作？

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

Error trying invoke business network. Error: No valid responses from any peers.\nResponse from attempted peer comms was an error: Error: chaincode error (status: 500, message: ReferenceError: identifier 'fetch' undefined

（使用 javascripts 同构获取 - require('isomorphic-fetch')）

这个事务在我运行 npm test 时从我的命令行运行，所以我认为它一定与 docker 容器有关运行对等镜像没有 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码功能。您应该能够将依赖项添加到 package.json。

例如

{
  "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"
  }
}

请参阅 documentation 以了解 fabric-chaincode-node 以编写您自己的 node.js 链代码。注意peer在创建容器的时候会执行npm install
