Hyperledger fabric Hyperledger fabcar客户端可以'；t连接到对等节点

两个月前，我使用Hyperledger Fabric编写了一个应用程序。现在，我试图再次运行它，但我得到了错误，我无法解决它。因此，我再次访问Hyperledger Fabric doc（），并重新安装所有内容（包括cmd工具、docker图像，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。我所做的是：

• 使用cmd（

  curl-sSL）下载结构示例repohttps://xxx/2ysbOFE |bash-s--2.1.0 1.4.6 0.4.18

  ）

• 然后转到fabcar/目录并运行

  /startFabric.sh

• 然后转到fabcar/javascript/目录并运行

  npm安装和&node-enrollAdmin.js和&node-registerUser.js和&node-invoke.js

但是，我再次遇到此错误：

我使用docker ps：

看来一切都很顺利。订购方节点docker日志为：

似乎订购方无法连接到某个对象（可能是对等节点）。因此，我认为可能存在一些问题：

• 可能对等节点的网络出现故障，我们无法连接到它
• 也许NodeJS Fabric SDK有缺陷，GRPC客户端无法正常工作
• 也许我的电脑坏了

你能帮帮我吗？谢谢
