build github.com/golangci/golangci-lint/cmd/golangci-lint: cannot find module for path github.com/kisielk/errcheck/golangci

The problem seems to be that the go tool is ignoring the github.com/kisielk/errcheck/golangci package in vendor. It gets confused because there is no package on GitHub at that path. Perhaps the path should be github.com/golangci/errcheck?

hi!
the preferred way to install golangci-lint is to use binary releases.
But I'm planning to support go modules.

v1.10.2 supports installation via go modules:
