spinner

spinner copied to clipboard

I am just taking simplest example to test the spinner:

func main() {

	s := spinner.New(spinner.CharSets[9], 100*time.Millisecond) // Build our new spinner
	s.Start()                                                   // Start the spinner
	time.Sleep(4 * time.Second)                                 // Run for some time to simulate work
	s.Stop()

}

and I get this stack of errors, any idea what is the issue? go version: go1.17.1 darwin/amd64

I've tried this on my mac amd64 with Go 1.16 and 1.17 and am not seeing this. Is it possible to upgrade to a newer version of Go and test again? Curious why there are references to "golang.org/x/sys/unix" in there.

@briandowns may be because this project's go.mod requires github.com/mattn/go-isatty, which in turn requires golang.org/x/sys/unix.

@SamiAlsubhi what version of macOS is this running against? Is it an Intel or ARM (M1) Mac? Does the same happen on the latest Go release (1.17.8)?

He stated go1.17.1 darwin/amd64 and I've asked him to upgrade and try again.

Ah I missed the Go version there. 👍 MacOS version can also be a factor, so it could be helpful to know that too. I have a few Mac's laying around I could maybe test with (depending on the OS version).
