Question

版本：

OS：具有Ubuntu 16.04的VM

节点：v8.11.4

PostgreSQL：9.5.14

docker：18.06.1-ce

docker-compose：1.13.0

我正在关注这个Hyperledger作曲家教程：https://hyperledger.github.io/composer/latest/tutorials/deploy-to-fabric-multi-org.html。运行命令后：

./byfn.sh -m up -s couchdb -a

我通过输入以下内容加入了第三方组织到业务网络：

eyfn.sh generate -c mychannel
eyfn.sh up -c mychannel -s couchdb

然后我已经成功建立了作曲家的业务网络并在操场上进行了测试

我打算使用Hyperledger Explorer工具可视化交易数量及其详细信息。

我通过以下链接逐步进行了操作：https://github.com/hyperledger/blockchain-explorer

我的config.json如下：

在新控制台中键入命令时，将启动Hyperledger Explorer：

./start.sh

Hyperledger Explorer无法启动，并且在控制台日志中引发以下错误：

 postgres://hppoc:password@127.0.0.1:5432/fabricexplorer
<<<<<<<<<<<<<<<<<<<<<<<<<< Explorer Error >>>>>>>>>>>>>>>>>>>>>
TypeError: Cannot read property 'size' of undefined
    at Platform.initialize (/home/diogosilva/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

有人可以帮我吗？

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，这意味着由于某种原因未能加载config.json。您需要使用以下观点进行审查：

检查日志/app/app.log
与原始config.json的区别
版本（您使用的是哪个版本？Fabric 1.1或1.2 / Explorer版本3.5或3.6）

启动Hyperledger Explorer时出错
