Warning: PhantomJS not found

I have installed nodejs 0.10.15 on debian 6. Using npm I have then installed: ``` sudo npm install grunt-cli -g ``` I have also executed npm install in my local test directory (downloading the necessary dependencies to the node_modules directory) which contains the following package.json file: ``` { "name": "sample-name", "version": "1.4.0", "devDependencies": { "grunt": "~0.4.1", "grunt-contrib-qunit": ">0.0.0", "grunt-qunit-istanbul": ">0.0.0" } } ``` here is the output when installing phantomjs: ``` ... Writing location.js file Done. Phantomjs binary available at /home/myuser/Test/node_modules/grunt-contrib-qunit/node_modules/grunt-lib-phantomjs/node_modules/phantomjs/lib/phantom/bin/phantomjs Done. Phantomjs binary available at /home/myuser/Test/node_modules/grunt-qunit-istanbul/node_modules/grunt-lib-phantomjs-istanbul/node_modules/phantomjs/lib/phantom/bin/phantomjs grunt@0.4.1 node_modules/grunt ├── which@1.0.5 ... ``` But when I run grunt test from the test dir I get: ``` Running PhantomJS...ERROR >> In order for this task to work properly, PhantomJS must be installed locally >> via NPM. If you're seeing this message, generally that means the NPM install >> has failed. Please submit an issue providing as much detail as possible at: >> https://github.com/gruntjs/grunt-lib-phantomjs/issues Warning: PhantomJS not found. Use --force to continue. ``` If I run the phantomjs script installed in the previous specified location nothing happens, I get exit code 127 though (indicating problem PATH :http://tldp.org/LDP/abs/html/exitcodes.html). If I cat the phantomjs bash script it looks like this: ``` #!/usr/bin/env node var path = require('path') var spawn = require('child_process').spawn var binPath = require(path.join(__dirname, '..', 'lib', 'phantomjs')).path var args = process.argv.slice(2) // For Node 0.6 compatibility, pipe the streams manually, instead of using // `{ stdio: 'inherit' }`. var cp = spawn(binPath, args) cp.stdout.pipe(process.stdout) cp.stderr.pipe(process.stderr) cp.on('exit', process.exit) process.on('SIGTERM', function() { cp.kill('SIGTERM') process.exit(1) }) ``` As I understand this means that phantomjs is executed inside node. If I start node enter the path var I get: ``` :~$ env node > var path = require('path') undefined > ``` (which I understand is default behavior: node.js displays "undefined" on the console) Any suggestions to further debug this problem?
