Warning: PhantomJS not found

Question

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

[email protected] node_modules/grunt
├── [email protected]
...

But when I run grunt test from the test dir I get:

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?

Answer 1

Try running

npm uninstall phantomjs

then running

npm install phantomjs -g

This should make sure phantom's installed with the command line, so that grunt can use it, and also should make sure that it installed cleanly.
