Babel Standalone not Working on Local HTTP Server

I'm having trouble getting Babel to work on my local environment. I am running a local HTTP Server with Python. I'm getting this error:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at file:///Users/nikkismacbookpro/Documents/Treehouse_Files/React_Basics/scoreboard/app.js. (Reason: CORS request not http).

I have tried using firefox (my default) and chrome. I have gotten the same error on both browsers. I also tried adding the attribute "charset='utf-8'" (found on a stack overflow answer), but that also did not work.

The error message you pastet looks like you're trying to access a file via an absolute path on the file system. If you use a local server to serve your files, you should avoid mixing it with accessing files through the file system.

It was working fine before I added the babel library, though. And the only times I use the file system to access files is when I source my css and javascript files:

<head> <meta charset="utf-8"> <title>Scoreboard</title> <link rel="stylesheet" href="app.css" /> </head>

<body> <div id="root"></div> <script crossorigin src="https://unpkg.com/react@16/umd/react.development.js"></script> <script crossorigin src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script> <script src="https://unpkg.com/@babel/standalone/babel.min.js"></script> <script type="text/babel" src="app.js"></script> </body>

How do I access those files without referencing them directly? I'm pretty sure I'm doing it the same way Giul does it in the video.
