invalid operation: kr == nil (mismatched types csr.KeyRequest and nil)

My Go Version:

go version go1.14.4 darwin/amd64

When I go get github.com/securekey/fabric-examples/fabric-cli/cmd/fabric-cli I get to following error:

# github.com/hyperledger/fabric-sdk-go/internal/github.com/hyperledger/fabric-ca/util
../../../Dev/src/github.com/hyperledger/fabric-sdk-go/internal/github.com/hyperledger/fabric-ca/util/csp.go:46:8: invalid operation: kr == nil (mismatched types csr.KeyRequest and nil)

	have (<-chan time.Time, string, string)
	want (context.Context, <-chan time.Time, string, string)

Does that means the version of fabric related packages is not right?

../../../Dev is my GOPATH.
