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

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

Can anybody tell me where am i going wrong?

回答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.

I commented these lines in EventHub.js. It's required only for state log. For example:

<br/>
<i>         var state = -1;<br/>
            //if(self._stream) state = self._stream.call.channel_.getConnectivityState();<br/>
            logger.debug('on.data - grpc stream state :%s',state);<br/>
</i><br/><br/>

it works fine now.

Thank you Anjy, updating grpc module worked fine.

I'm still getting below error after commenting the line in EventHub.js

回答5:

Faced the same issue while building the web docker edit package.json add the line "dependencies": { "grpc" : "1.9.1",

build the docker again issue the docker compose agin ! it works

回答6:

I was trying to connect the composer bna to IBM blockchain, and I tried out installing grpc 1.9.1.. and even 1.10.1.. I tried out like everything, and the only thing that worked was doing as Kataus suggested, I commented out the lines relate to the getConnectivity state, and it finally connected to the IBM blockchain network I had.
