Typescript can't be compiled in vs code: error TS5007

Question

I just installed vs code v1 (the latest version) and typescript v1.8.10 (latest version). I followed the exact instruction from vs code website but can't get vs code to build the simplest typescript file though I can manually build it by running tsc command in git bash. The output from the vs code is:

error TS5007: Cannot resolve referenced file: '.'.
error TS5023: Unknown option 'p'
Use the '--help' flag to see options.

This is the my helloworld.ts file which really can't be simpler:

class Greet {
    private _message : string;
    constructor(message : string) {
        this._message = message;
    }
    Say = () => console.log(this._message);
}

var g = new Greet('hello typescript!');
g.Say();

This is my tasks.json file:

{
    // See http://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "0.1.0",
    "command": "tsc",
    "isShellCommand": true,
    "args": ["-p", "."],
    "showOutput": "silent",
    "problemMatcher": "$tsc"
}

and tsconfig.json:

{
    "compilerOptions": {
        "target": "es6",
        "module": "commonjs",
        "sourceMap": true
    }
}

Answer 1

Maybe it can help as mentioned at (VS Code, error, TS5023) Unknown compiler option 'p'

Open your environment settings and remove the old Typescript from your system PATH variable. Mine was C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\.

1. Hold Windows Button and hit the PauseBreak key
2. Advanced System Settings
3. Environment Variables
4. In the "System" panel (the bottom in Windows 10) select the Path variable and click Edit
5. Find and highlight an old version like C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\ in the text, delete it. Press "OK" three times.
6. Restart VS Code
