I've switched to Go not so long ago. I've chosen JetBrains Gogland as IDE. I like both: Go and IDE, except a one issue. I don't know whether it is an issue with IDE or with Go lang configuration on macOS Sierra. But when I'm trying start debuging for a test from Gogland, the build fails with message:
