我正在尝试在我设置的超级账本结构网络中安装和实例化链代码。我已经在 node.js 中编写了链代码，它可以完美地从 cli 容器的 bash 中安装。但是当我尝试实例化链码时，它会在等待 5 分钟后给出错误。当我检查几秒钟后退出的短寿命链代码容器的日志时，我只看到一行：npm ERR！缺少脚本：开始。

当我第一次遇到这个错误时，我没有在 package.json 中包含启动脚本并立即意识到我的错误。我在 package.json 中包含了启动脚本，但在多次重试后仍然出现此错误。我已经多次重启网络并修剪了 docker 卷。

为什么会出现此错误以及如何解决？

这是安装和实例化（有错误）：

Here's the log of this short lived chaincode container:
$ docker logs a7eca3bf67c5
npm ERR! missing script: start

Here's my package.json:
{
  "name": "kyc",
  "version": "1.0.0",
  "description": "kyc chaincode in node",
  "main": "kyc.js",
  "dependencies": {
    "fabric-shim": "~1.4.0"
  },
  "devDependencies": {},
  "scripts": {
    "start": "node kyc.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}
``````````````



I expect it to not give this error as start script has been provided in package.json
