Typescript: Cannot read property 'args' of undefined

[yakiler]

TypeScript Version: 2.4.1 / nightly (2.5.0-dev.201xxxxx)

Code

// A *self-contained* demonstration of the problem follows...
class Greet 
{
       say():void
       {
           console.log( "Hello world" );
       }
}

I initialized a TS project in cmd, And then generate a tsconfig.json file.I wrote a Greet.ts file.
Now I use ctrl + shift + b to compile in vsCode ,Then i got a hint "Cannot read property 'args' of undefined"
Expected behavior:
Compiled to get a JS file
Actual behavior:
Found a hint

Yup!.. I too face the same issue here, Posted this in StackOverflow at the below URL,

Any solutions?

According to that SO question, this might actually be an issue with Visual Studio Code integration, since runnning tsc directly works fine (although I would advise the poster of this issue to do the same and see if that works). Can you try adding this to a new ".vscode/tasks.json" file and running the command again?

{
    "version": "0.1.0",
    "command": "tsc",
    "isShellCommand": true,
    "showOutput": "always"
}
