Hi,
I'm on Windows, I had Go 1.7.4 installed from the MSI installer. Today I decided to upgrade to Go 1.8, so I downloaded the new MSI, ran it and that was it. However, first package I tried to install I got the following errors: G:\Gopath\src\github.com\google> go get -u -v github.com/vrischmann/ghclone github.com/vrischmann/ghclone (download) github.com/google/go-github (download) github.com/google/go-querystring (download) runtime/internal/atomic runtime # runtime C:\Go\src\runtime\utf8.go:16: surrogateMin redeclared in this block previous declaration at C:\Go\src\runtime\rune.go:49 C:\Go\src\runtime\utf8.go:17: surrogateMax redeclared in this block previous declaration at C:\Go\src\runtime\rune.go:50 C:\Go\src\runtime\utf8.go:21: t1 redeclared in this block previous declaration at C:\Go\src\runtime\rune.go:31 C:\Go\src\runtime\utf8.go:22: tx redeclared in this block previous declaration at C:\Go\src\runtime\rune.go:32 C:\Go\src\runtime\utf8.go:23: t2 redeclared in this block previous declaration at C:\Go\src\runtime\rune.go:33 C:\Go\src\runtime\utf8.go:24: t3 redeclared in this block previous declaration at C:\Go\src\runtime\rune.go:34 C:\Go\src\runtime\utf8.go:25: t4 redeclared in this block previous declaration at C:\Go\src\runtime\rune.go:35 C:\Go\src\runtime\utf8.go:26: t5 redeclared in this block previous declaration at C:\Go\src\runtime\rune.go:36 C:\Go\src\runtime\utf8.go:28: maskx redeclared in this block previous declaration at C:\Go\src\runtime\rune.go:43 I got it working by uninstalling Go, removing the directory completely in the explorer, and reinstalled Go. Shouldn't the MSI installer remove the previous Go installation before installing the new files ? Not sure if I did something wrong. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
