PHPPhantomJS not loading PhantomJS Module

I am trying to use PHP PhantomJS to load a page, but I get the error

Fatal error:  Uncaught JonnyW\PhantomJs\Exception\ProcedureFailedException: Error when executing PhantomJs procedure - File does not exist or is not executable: bin/phantomjs in /Volumes/WWW ROOT/namechase/www/vendor/jonnyw/php-phantomjs/src/JonnyW/PhantomJs/Procedure/Procedure.php:138
Stack trace:

#2 {main}
  thrown in /Volumes/WWW ROOT/namechase/www/vendor/jonnyw/php-phantomjs/src/JonnyW/PhantomJs/Procedure/Procedure.php on line 138

This only happens on one of my test domains, and not the other.

The code I am running on both domains is identical, but doesn't work on one of the two test beds. Both are running on the same machine, just using different virtual hosts, but only one is returning the error.

require $_SERVER['DOCUMENT_ROOT'] . '/vendor/autoload.php';

echo '<pre>';
use JonnyW\PhantomJs\Client;

$client = Client::getInstance();
$delay = 5; // 5 seconds

$request = $client->getMessageFactory()->createRequest('https://google.com', 'GET');
$request->setDelay($delay);
/**
 * @see JonnyW\PhantomJs\Http\Response
 **/
$response = $client->getMessageFactory()->createResponse();

// Send the request
$client->send($request, $response);

if($response->getStatus() === 200) {

    // Dump the requested page content
    echo $response->getContent();
}

I have tried setting the path to phantomjs in the composer.json file using

"config": {
  "bin-dir": "/usr/local/bin"
}

but this doesn't seem to make any difference

Solution

When you run Composer to install your packages the PhantomJS-Installer script will fetch PhantomJS and install it into the /bin folder of the project.

It will never land in /usr/local/bin, except when you manually install or move it there.

You get the following error message: File does not exist or is not executable: bin/phantomjs.

Firstly, i would check, if the file is correctly fetched and installed into the bin folder. (If the file is not installed into the bin folder of your project, then the installer script should give you an error during the Composer run.)

Secondly, i would check file permissions. Normally the installer takes care of that, but just take a look, if the executable flag +x is set.
