'parcel' is not recognized as an internal or external command, operable program or batch file. ERROR for Parcel bundler in Vanilla TYPESCRIPT Code - node.js

Question

This error is showed up when I ran the code for an Arkanoid Game published on freecodecamp articles. I am not able to set up the configuration correctly for the game. I expected it to run the game but it didn't do the same. While debugging it kept throwing errors regarding its build. I have no idea as I have learned it online but this error is not getting resolve.
I am attaching both the debugger image and the error image along with the log file text, where it showed the error.

}
The above codes are the mainframe of the game. Hope it helps to resolve.

Answer 1

To be able to load an ES module, we need to set “type”: “module” in this file or, as an alternative, we can use the .mjs file extension as against the usual .js file extension.
In your package.json file add this:
{
"type": "module",
}
For an example:
{
"name": "esm",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"type": "module",
"author": "",
"license": "ISC"
}
If this doesn't work uninstalling both global and local versions of parcel:
npm uninstall parcel
npm uninstall -g parcel
Then install it using this command:
npm install parcel --save-dev

I have been getting this error while using parcel index.html to start the parcel deployment server.
On reading the official documentation I found out the correct command to do that:
npx parcel index.html
It worked as expected on using that command!
