Build error in code

Getting Help

I am getting following error. Is this due to go version issue or something ?

Hi @Manisha_Mahapatra,

Welcome to the forum.

It looks like your code tries to access a closed leveldb instance. Without seeing the code that triggers this error, troubleshooting this error is difficult.

Hi,
I’m trying to build the development environment for hyperledger fabric from : GitHub - hyperledger/fabric: Hyperledger Fabric is an enterprise-grade permissioned distributed ledger framework for developing solutions and applications. Its modular and versatile design satisfies a broad range of industry use cases. It offers a unique approach to consensus that enables performance at scale while preserving privacy., fabric 2.2.14
While running make command I am getting leveldb: closed error.
As the architecture code has been implemented in golang, so I am hoping to get some support on this issue.
command used : make dist-clean all

Aw, sorry, I lost track of this conversation.

If the error occurs when following the steps for building the Hyperledger Fabric environment, then it’s likely that some prerequisites have not been met.

If the problem was in the code, everyone who tries building that environment would stumble upon this error. However, I did not find an issue in the repo about this particular error.

I think the best next step is to reach out to the Hyperledger Fabric team or community for help.
