启动 Hyperledger Explorer 时出错

Question

版本：

操作系统：使用 Ubuntu 16.04 的虚拟机

节点：v8.11.4

PostgreSQL：9.5.14

码头工人：18.06.1-ce

码头工人撰写：1.13.0

我正在关注这个超级账本作曲家教程：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

我已通过键入以下内容将第三个组织加入业务网络：

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

那我已经成功搭建了composer业务网络，并在操场上测试了

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

我按照这个链接一步一步地执行：https://github.com/hyperledger/blockchain-explorer

我的 config.json 如下：

在新控制台中输入启动 Hyperledger Explorer 的命令时：

./start.sh

Hyperledger Explorer 未启动，并且在控制台日志中抛出以下错误：

 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)

有人可以帮帮我吗？

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无法加载您的 config.json。您需要从以下几个角度进行回顾：

• 查看日志/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）
