两个月前，我使用 Hyperledger Fabric 编写了一个应用程序。现在，我尝试再次运行它，但出现错误并且无法解决。所以我再次查看 Hyperledger Fabric 文档（https://hyperledger-fabric.readthedocs.io/en/latest/install.html），并重新安装所有内容（包括 cmd 工具、docker 映像甚至我的 MacOS）。

我尝试了两个版本（v2.0.1 和 v2.1.0），我的节点版本是 v12。我要做的是：

  • curl -sSL https://xxx/2ysbOFE | bash -s -- 2.1.0 1.4.6 0.4.18使用 cmd ( )下载 fabric-samples repo

  • 并进入 fabcar/ 目录并运行./startFabric.sh

  • 并进入 fabrcar/javascript/ 目录并运行npm install && node enrollAdmin.js && node registerUser.js && node invoke.js

但是，我再次遇到此错误：

我使用 docker ps： 在此处输入图像描述

似乎一切顺利。排序节点 docker logs 是：

似乎订购者无法连接到某些东西（可能是对等节点）。所以我认为有一些可能的问题：

  • 也许对等节点的网络出现故障，我们无法连接到它。
  • 也许 NodeJS Fabric SDK 有问题，它的 GRPC 客户端不能正常工作。
  • 也许我的电脑出了问题。

请你帮助我好吗？谢谢！！！
