使用fabric v1.2启动hyperledger explorer时出错

Question

启动资源管理器时出现以下错误：

<<<<<<<<<<<<<<<<<<<<<<<<<< Explorer Error >>>>>>>>>>>>>>>>>>>>>
TypeError: Cannot read property 'size' of undefined
    at Platform.initialize (/home/kp/Desktop/blockchain-explorer/app/platform/fabric/Platform.js:52:45)
    at <anonymous>
    at process._tickCallback (internal/process/next_tick.js:188:7)
Received kill signal, shutting down gracefully
Closed out connections

使用Fabric v1.2和Explorerv0.3.6，我用grpc替换了grpcs，但这也没有多大帮助。不确定在配置文件中将“size”属性传递到何处。

Answer 1

TypeError: Cannot read property 'size' of undefined
at Platform.initialize (/home/kp/Desktop/blockchain-explorer/app/platform/fabric/Platform.js:52:45)

根据Platform.js的说法，这意味着由于某种原因无法加载你的config.json。您需要查看以下视点：

• Check logs/app/app.log
• Difference from orignal config.json

我不认为它与这个问题有关，但是当禁用TLS时，您需要将config.json中的'tlsEnable‘改为'false’。

{
   "network-configs": {
     "network-1": {
       "clients": {
         "client-1": {
           "tlsEnable": false,
                        ^^^^^

你对这个问题有什么解决方案吗？我使用link https://github.com/hyperledger/blockchain-explorer逐步部署了Hyperledger Explorer，在使用fabric v1.2和composer v0.20.0时遇到了与您相同的错误

Answer 3

我得到了同样的错误，在我这边，“network-configs”标签丢失了。在控制台日志中，就在此错误之前，我收到了一条消息，显示‘*初始化已启动hyperledger fabric platform *，'，未定义

如果检查platform.js中的代码，您可以看到未定义的变量对应于网络配置。

我在原始文件夹中创建了一个简单的config.json文件，如下所示：

{

"network-configs": {

    "first-network": {

        "name": "firstnetwork",

        "profile": "./connection-profile/first-network.json",

        "enableAuthentication": false

    }

},

"license": "Apache-2.0"

然后我创建了一个完整的档案文档，以

{

"name": "first-network",

"version": "1.0.0",

我不确定是否真的有必要拆分文件，但不管怎样，对我来说，这个过程解决了这个问题。
