Question

我使用Node.js API编写了链代码，现在我试图实例化。

图片：hyperledger / fabric-peer：1.4.5

我的package.json具有以下来源：

{
    "name": "democontract",
    "version": "1.0.0",
    "description": "Document Contract",
    "main": "index.js",
    "engines": {
        "node": ">=8.4.0",
        "npm": ">=5.3.0"
    },
    "scripts": {
        "lint": "eslint .",
        "pretest": "npm run lint",
        "start": "fabric-chaincode-node start",
        "mocha": "mocha test --recursive"
    },
    "engine-strict": true,
    "license": "Apache-2.0",
    "private": true,
    "dependencies": {
        "mkdirp": ">=0.5.5",
        "openpgp": "^4.10.0",
        "fabric-chaincode-api": "^1.4.0",
        "fabric-shim": "^1.4.0"
    },
    "devDependencies": {
        "chai": "^4.1.2",
        "chai-as-promised": "^7.1.1",
        "eslint": "^4.19.1",
        "mocha": "^5.2.0",
        "nyc": "^12.0.2",
        "sinon": "^6.0.0",
        "sinon-chai": "^3.2.0"
    }
}

但是当我在CLI容器中调用以实例化链码（democontract）时：

peer chaincode instantiate -C $CHANNELNAME -n $CHCODENAME -v $CHCODEVERSION -o $ORDERERNAME \
    -c '{"Args":["ContractDocument:instantiate"]}' \
    -P "OR('OrdererMSP.admin','Org1MSP.admin','Org1MSP.peer','Org1MSP.member')" \
    --tls --cafile $ORDERER_TLSCACERT --tlsRootCertFiles $CORE_PEER_TLS_ROOTCERT_FILE

我在PEER容器中接收到以下错误，并且链码无法实例化。

我不知道如何摆脱这种错误情况。拜托，你能帮我吗？

Answer 1

您可能正在使用不兼容版本的节点js。请使用超级账本结构版本检查节点js的受支持版本。

Answer 2

问题出在 package.json 内部。

代码段错误：

"dependencies": {
    "mkdirp": ">=0.5.5",
    "openpgp": "^4.10.0",
    "fabric-chaincode-api": "^1.4.0",
    "fabric-shim": "^1.4.0"
},

正确的代码段是：

"dependencies": {
    "mkdirp": ">=0.5.5",
    "openpgp": "^4.10.0",
    "fabric-contract-api": "^1.4.3",
    "fabric-shim": "^1.4.3"
},

从 fabric-chaincode-api 更改为 fabric-contract-api 。

我参考URL https://hyperledger.github.io/fabric-chaincode-node/master/api/tutorial-using-contractinterface.html中描述的软件包编写了package.json。

有关将来的参考，请参见下面的URL：
