What did you do?

I'm trying to update a dependency using go get:

$ grep zap go.mod
        go.uber.org/zap v1.15.0
$ go get go.uber.org/zap@latest
go: downloading go.uber.org/zap v1.19.0
go: downloading go.uber.org/atomic v1.7.0
go: downloading go.uber.org/multierr v1.6.0
# runtime/internal/sys
/usr/local/go/src/runtime/internal/sys/stubs.go:9:7: PtrSize redeclared in this block
        /usr/local/go/src/runtime/internal/sys/arch.go:24:38: previous declaration
/usr/local/go/src/runtime/internal/sys/stubs.go:10:24: undefined: Uintreg
/usr/local/go/src/runtime/internal/sys/stubs.go:16:7: StackGuardMultiplier redeclared in this block
        /usr/local/go/src/runtime/internal/sys/arch.go:27:74: previous declaration

I tried to upgrade a few different dependencies and all got the same error from runtime/internal/sys. This works when I use go 1.16. When using go 1.17 it always break, regardless the go directive in go.mod file (I've tried both 1.16 and 1.17)

What did you expect to see?

It should work as in go 1.16

What did you see instead?

Additional note: it throws the same error if I use a specific version instead of latest:

$ go get go.uber.org/zap@v1.19.0
# runtime/internal/sys

It looks like you unpacked Go 1.17 over an existing Go installation. Don't do that: unpack it in an empty directory. The files src/runtime/internal/sys/stubs.go and src/runtime/internal/sys/arch.go existed in Go 1.16 and earlier releases but were removed in Go 1.17.
