I encountered an error while installing Fabric CA with the go get command-CodePudding

when executing

go get -u github.com/hyperledger/fabric-ca/cmd/

I get the following error:

go get: installing executables with 'go get' in module mode is deprecated.
Use 'go install pkg@version' instead.   
For more information, see https://golang.org/doc/go-get-install-deprecation
    or run 'go help get' or 'go help install'.

go version

go version go1.17.2 linux/amd64

CodePudding user response：

go 1.17.2 isn't a supported version for fabric-ca 1.5.2 check the release notes for the supported version here https://github.com/hyperledger/fabric-ca/releases/tag/v1.5.2

however there is also an issue with a dependency that has changed an api such that using the -u option on go get means that it will download and use an incompatible version. This applies only to the server so for the server

go get github.com/hyperledger/fabric-ca/cmd/fabric-ca-server

should work, but you can also do

go get github.com/hyperledger/fabric-ca/cmd/...

to include a client build as well

You can of course just get official builds from https://github.com/hyperledger/fabric-ca/releases/tag/v1.5.2
