Why does this say "PhantomJS not found?"

I'm working with PhantomJS (http://phantomjs.org/screen-capture.html). The example is a real straight forward looking piece of code, but I keep getting an error that says "phantomjs not found." See the screenshot below:

command line screen
...and then the rasterize.js code:

"use strict";
var page = require('webpage').create(),
    system = require('system'),
    address, output, size;

if (system.args.length < 3 || system.args.length > 5) {
    console.log('Usage: rasterize.js URL filename [paperwidth*paperheight|paperformat] [zoom]');
    console.log('  paper (pdf output) examples: "5in*7.5in", "10cm*20cm", "A4", "Letter"');
    console.log('  image (png/jpg output) examples: "1920px" entire page, window width 1920px');
    console.log('                                   "800px*600px" window, clipped to 800x600');
} else {
    address = system.args[1];
    output = system.args[2];
    page.viewportSize = { width: 600, height: 600 };
    if (system.args.length > 3 && system.args[2].substr(-4) === ".pdf") {
        size = system.args[3].split('*');
        page.paperSize = size.length === 2 ? { width: size[0], height: size[1], margin: '0px' }
                                           : { format: system.args[3], orientation: 'portrait', margin: '1cm' };
    } else if (system.args.length > 3 && system.args[3].substr(-2) === "px") {
        size = system.args[3].split('*');
        if (size.length === 2) {
            pageWidth = parseInt(size[0], 10);
            pageHeight = parseInt(size[1], 10);
            page.viewportSize = { width: pageWidth, height: pageHeight };
            page.clipRect = { top: 0, left: 0, width: pageWidth, height: pageHeight };
        } else {
            console.log("size:", system.args[3]);
            pageWidth = parseInt(system.args[3], 10);
            pageHeight = parseInt(pageWidth * 3/4, 10); // it's as good an assumption as any
            console.log ("pageHeight:",pageHeight);
            page.viewportSize = { width: pageWidth, height: pageHeight };
    if (system.args.length > 4) {
        page.zoomFactor = system.args[4];
    page.open(address, function (status) {
        if (status !== 'success') {
            console.log('Unable to load the address!');
        } else {
            window.setTimeout(function () {
            }, 60000);

What do you think? Why am I getting the error "phantomjs: not found

Are you sure phantomjs is not a folder.

Try ls -al in the command window to see what is displayed - if it is a folder then I suspect what you are looking for needs to be called with the folder name or from within the folder.

I did this:

$ ./phantomjs

...and I got phantomjs?

Is that right?
Julian HansenCommented:
I don't know - not familiar with phantomjs but if you did not get the file not found then it appears to have run.

Try your command line again like this (I have no way to test so please check spelling before running it)

./phantomjs rasterize.js http://ariya.github.io/svg/tiger.svg tiger.png

Julian, that did it!


If I start off with "cd /var/www/html/phantomjs" does that not put my "process space" within that directory? Why would I have to reference a file (phantomjs) as though it were one directory up from where I appear to be?
Dave BaldwinFixer of ProblemsCommented:
Many Linux versions do not allow you to execute a file directly in a directory.  Instead of 'phantomjs', you must use'./phantomjs'.  It's some kind of security 'feature'.

Thank you guys!

I have another question that's related to this, but I didn't want to wear out my welcome and allow this question to morph into two.
