Visual Studio Code "Cannot compile modules unless the '--module' flag is provided" error

I'm using Visual Studio Code 0.10.6 to compile a TypeScript 1.8 (beta) project. The editor is showing a "Cannot compile modules unless the '--module' flag is provided" error:

Cannot compile modules unless the '--module' flag is provided

However, I have value for the module property in my tsconfig.json:

{
    "compilerOptions": {
        "target": "es5",
        "module": "system",
        "noImplicitReturns": true,
        "noImplicitAny": true,
        "noFallthroughCasesInSwitch": true,
        "preserveConstEnums": true,
        "sourceMap": true,
        "outDir": "./src/scripts/compiled",
        "rootDir": "./src/scripts"
    },
    "exclude": [
        "node_modules",
        "jspm_packages"
    ]
}

The project compiles without errors (I'm using gulp-typescript to compile my TypeScript files), and I've restarted the editor multiple times.

Why is Visual Studio Code showing this error, even though my code is compiling without errors?

Visual Studio Code 0.10.6 hasn't build-in TypeScript 1.8 support yet.

Suppose you have install typescript 1.8 with npm install, add a line into .vscode/settings.json in your project to make use of it.

"typescript.tsdk": "./node_modules/typescript/lib"
