External script not working in PaperJS v0.9.22

I am new to paperJS and I'm trying to include an external paperscript file in html, but it isn't working. While the inline scripting is working fine. My code are:

HTML Code:

<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="js/paper.js"></script>
</head>
<body>
    <script type="text/paperscript" src = "js/myScript.js" canvas = "myCanvas" >
    </script>
    <canvas id="myCanvas" resize></canvas>

paperScript Code (myScript.js):

// Create a Paper.js Path to draw a line into it:
var path = new Path();
// Give the stroke a color
path.strokeColor = 'black';
var start = new Point(100, 100);
// Move to start and draw a line from there
path.moveTo(start);
// Note the plus operator on Point objects.
// PaperScript does that for us, and much more!
path.lineTo(start + [ 100, -50 ]);

I found an old link on stackOverflow which says that using version 0.9.10 fix the problem. But is that issue still not fixed in newer version? Here's the link:

Actually I found the solution via another student in Udemy -Git link here. Go to the paper-full.js (it works only with the downloaded version, not CDN) and transform the line

xhr.open((options.method || 'get').toUpperCase(), options.url,
Base.pick(options.async, true));

into only

xhr.open((options.method || 'get').toUpperCase(), options.url);

I understood that's not to be used in normal website as it's against a security protocols, so it's just for practicing. The async method is optional according to Paperjs. By the way, for me it works on Firefox, but not in Chrome.

This is not paperJs issue. Here I was trying to load a resource from the local file system, which chrome doesn't permit (Violation of its same-origin policy) and so we need a local web server.Why?

Local web server can be setup using WAMP (on Windows), MAMP (on OS X), LAMP(for ubuntu). It can aslo be setup by Python http-server and NodeJS http-server.

The only guess I can make based on the information here is that you're loading paper-core.js, not paper-full.js. paperscript is not implemented in paper-core.js.

The behavior if it's paper-core.js would be that your code is never called because there is nothing to interpret paperscript.
