Jenkins & NodeJS plugin - Permission Denied error

Question

I've managed to setup a Jenkins instance on a Raspberry Pi, and have got as far as installing the NodeJS plugin before I eventually hit this stumbling block:

I'm not doing anything particularly special, this is an initial test to ensure the NodeJS plugin works:

var sys = require('sys');
sys.puts('NodeJS Test');
sys.puts('***********');
sys.puts('Hello World');

This works if I log in as the Jenkins user, and run it myself:

jenkins@raspberrypi:~$ node test.js
NodeJS Test
***********
Hello World
jenkins@raspberrypi:~$ 

I've trawled the internet, and cannot seem to find anything specific; pretty sure its not file permissions specifically (Workspace directory has full access to all users)

I had the same problem. For me it was the nodejs plugin configurations, under "global configurations" in jenkins. My "node" application (symlink) was located at /usr/local/bin/node. And my "installation directory" was set to /usr/local/bin/. I changed that too /usr/local/ and it start working! :)

Note that this is when you aren't using "install automatically"-function of the nodejs plugin.
