你不需要做任何事情。
Delve默认将stdout和stderr打印到其控制台。我在MacOS ElCapitan上尝试过这个，使用的是Delve版本0.11.0-alpha。
在你的GOPATH的正确子目录中有一个main.go文件：
package main
import "fmt"
import "os"
func main() {
fmt.Fprintf(os.Stderr, "Writing something to stderr\n")
fmt.Fprintf(os.Stdout, "Writing something to stdout\n")
}
然后在与main.go相同的目录中运行Delve：
$ dlv debug
Type 'help' for list of commands.
(dlv) restart
Process restarted with PID 70964
(dlv) c
Writing something to stderr
Writing something to stdout
Process 70964 has exited with status 0
(dlv)

You do not need to do anything.
Delve by default prints the stdout and stderr to its console.
I have tried this in MacOS ElCapitan delve version 0.11.0-alpha
Have a main.go in the right subdir in your GOPATH
package main
import "fmt"
import "os"
func main() {
fmt.Fprintf(os.Stderr, "Writing something to stderr\n")
fmt.Fprintf(os.Stdout, "Writing something to stdout\n")
}
Then run the delve in the same dir as the main.go
$ dlv debug
Type 'help' for list of commands.
(dlv) restart
Process restarted with PID 70964
(dlv) c
Writing something to stderr
Writing something to stdout
Process 70964 has exited with status 0
(dlv)
