Fixing the "tl-node is not recognized" error in VS Code and TypeScript

After installing VS Code, I am struggling to figure out how to compile TypeScript code in VSCODE.

Some resources mention that VSCODE includes a "stable" version of TypeScript, while others suggest installing TypeScript separately. When I try to write the following simple code in a sample.ts file:

// sample.ts

function add(x: number, y: number): number {
    return x + y;
}

console.log(add(2,2)); // 4

I encounter this error:

[Running] ts-node "i:\UserData\Ted\Documents\typescript-test\sample.ts" 'ts-node' is not recognized as an internal or external command, operable program or batch file.

How can I resolve this issue? Does VS Code come with TypeScript installed for compiling and running code? If so, what step am I missing, and if not, how do I address it?

I have used npm to install TypeScript (located in C:\Users\Ted\AppData\Roaming\npm\node_modules\typescript).

Answer №1

It appears that the functionality you are referring to requires a global installation of ts-node.

If you encounter any issues with this, please submit an issue at https://github.com/Microsoft/vscode/issues.

The installation process should handle this for you.

However, it seems that this feature is still in its experimental stages as there are some noticeable bugs present.

One such bug is that if external packages are used, this feature may not function correctly as it does not load or resolve those dependencies.

Please consider reporting these issues so they can be addressed. :)

Thank you for bringing this to my attention. I was unaware of this feature's existence before. :)
