Hi,
I’m trying to run a script using System.cmd/3 but I’m getting an :enoent error.
Here’s the error output:
[error] Task #PID<0.427.0> started from #PID<0.373.0> terminating
** (stop) :enoent

You probably do not have
echoinPATH.Please check on a terminal if
which -a echogives you at least one result that is not a function or built-in.Then check if the prefix of that output is available in the PATH visible to your application (
System.get_env("PATH")).Zesky665
I think I don’t, but it works in the cmd when I type it in manually.
I got:
'which' is not recognized as an internal or external command, operable program or batch file.I tried
System.get_env()iniex, it outputted a list that did not include echo.Update:
I’m on win10 and System.cmd() gives me the same error regardless of what I put into the first argument.

So you are on windows? There is no
echoexecutable then, with a bit of luckSystem.cmd("cmd", ["echo", "foo"])might work, but no guarantees for nothing…Zesky665
I found this just before you posted this reply.
Basically it’s the same thing and it works
