How to invoke child 'go' process in playground?

[Xiangdong JI]

Hi,

Given a command execution like "cmd := exec.CommandContext(ctx, "go", "run", file)" playground reports the following error:

child error: exec: "go": executable file not found in $PATH

Could it be solved by specifying a full path for 'go', which path shall I use? Thanks a lot.

The Go playground does not allow running arbitrary external commands. No doubt primarily for security reasons. But also because the playground environment is not a complete virtualized OS. For example, try to execute

exec.Command("/bin/ls", "-la")

You'll get a "not implemented on nacl" error. See https://blog.golang.org/playground
