问题描述

无法成功调用:: TypeError:无法读取未定义的属性'getConnectivityState' /opt/share/hyperledger/node_modules/fabric-client/lib/EventHub.js:355 if(self._stream)state = self. stream.call.channel .getConnectivityState(); ^

我正在使用以下链接中提到的必备软件的最新版本:

I am using latest version of pre-requisites as mentioned in below link:

http://hyperledger-fabric.readthedocs .io/zh-CN/release-1.1/getting_started.html#install-prerequisites

有人可以告诉我我要去哪里错吗?

Can anybody tell me where am i going wrong?

推荐答案

是的，这是由于3天前发布了新版本的grpc(v1.11.0).该版本由fabric-client控制，并采用最新版本.您需要删除grpc模块，然后使用npm install grpc@1.9.1重新安装它.这样可以解决问题.展望未来，在Hyperledger解决此问题之前，您可能需要在package.json中将grpc固定为1.9.1.

Yes, this is due to a new version of grpc released 3 days ago (v1.11.0). The version is controlled by fabric-client and it takes the latest available. You need to delete the grpc module and reinstall it with npm install grpc@1.9.1. This will fix the issue. Going forward you may need to have grpc fixed at 1.9.1 in your package.json until Hyperledger resolve this issue.
