Question

我正在尝试将Hyperledger Composer与Hyperledger Explorer结合使用。我已经在fabric-dev-servers上部署了一个简单的业务网络。在作曲者方面，它工作正常，并且能够与网络完美交互，但是当我尝试将其与Hyperledger Explorer集成时，在启动它时出现以下错误。

Answer 1

我也遇到过类似的问题，并通过以下步骤解决了该问题。

从给定的URL下载Explorer 3.5。
https://github.com/hyperledger/blockchain-explorer/tree/v0.3.5.1
Hyperledger Composer设置（更新config.json）
构建Hyperledger Explorer
运行Hyperledger Explorer

最后，它适用于Fabric 1.2和Composer@0.20。

我希望它能对您有所帮助！

Answer 2

查看您的config.json文件的格式，看来您使用的是旧版的Explorer，还是旧的config.json。仅在资源管理器3.7中添加了对Fabric 1.2（看起来像您正在使用的）的支持，并更改了config.json的结构。

所以，我建议以下内容：

更新到Explorer 3.7（分支版本3.7）。
遵循说明here。

将Hyperledger作曲器与资源管理器一起使用时出错
