couldn't get port by PID

[weichangdong]

gops memstats 27281
couldn't get port by PID: dial tcp 127.0.0.1:0: connect: can't assign requested address
when i use addr,long time no response.
i use go version go1.10 darwin/amd64.
i remember it works before,perhaps i updated the go version.

1、golang version
2、quote "github.com/google/gops/agent" in your code;
3、add code in you main func, such as:
if err := agent.Listen(agent.Options{}); err != nil {
log.Fatal(err)
}
4、go build your code
5、run your binary program
6、gops option according to gops doc

to use gops, you MUST set env of GOPS_CONFIG_DIR, otherwise, it use $HOME/.config for linux system, in case the dir does not exist, gops will mkdir, but for which you might have no permission to mkdir

func PIDFile(pid int) (string, error) {
gopsdir, err := ConfigDir()
if err != nil {
return "", err
}
return fmt.Sprintf("%s/%d", gopsdir, pid), nil
}
