Shell script / Python / Node / Newb lost ...

@howartp, you mean like this?

Code: Select all

import subprocess

command = ["/Users/myriam/.nvm/versions/node/v9.11.1/bin/ps4-waker", "standby", "-t", "30000", "env=node"]

proc = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

out, err = proc.communicate()

indigo.server.log(u"command error: %s" % err)


or something akin to that....

No.

subprocess.popen(command, err=stdpipe, out=stdpipe, env=node, shell=true)

That’s the shrunk version of what I mean...

you guys are machines!!

Here's the code I ran:

Code: Select all

import subprocess


command = ["/Users/myriam/.nvm/versions/node/v9.11.1/bin/ps4-waker", "standby", "-t", "30000"]

proc = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, env=node, shell=true)

out, err = proc.communicate()

indigo.server.log(u"command error: %s" % err)

Here's the error I'm now having:

Script Error embedded script: global name 'node' is not defined
Script Error Exception Traceback (most recent call shown last):

embedded script, line 6, at top level
NameError: global name 'node' is not defined

Code: Select all

import subprocess

command = "/usr/local/bin/ps4-waker standby -t 30000"

proc = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, env=‘node’, shell=True)

out, err = proc.communicate()

indigo.server.log(u"command error: %s" % err)

I’m thinking this?

I’ve reverted command back to my second reply about [commands, like, this].

I’ve also set path back to /usr/local/bin as I think that’s how you originally ran it - the env node should automatically find the path to /Miriam/.../node/.... etc without hard coding it, I think.

Getting a different error this time

Script Error embedded script: execve() arg 3 must be a mapping object
Script Error Exception Traceback (most recent call shown last):

embedded script, line 5, at top level

let's complicate things a bit !!!

I did not have a /usr/bin/node folder. I created one and created a symlink to the /Users/myriam/.nvm/versions/node/v9.11.1/bin/.

I ran the code again and I'm now getting the following error:

Script command error: env: node: Permission denied

You don’t need a usr/bin/node folder.

https://scriptingosx.com/2017/10/on-the-shebang/ is a good explanation of the shebang line, which explains env as a magic way of finding where node is installed.

that was an interesting read. I went ahead and removed the symlink.

Now i'm back to this error:
