title: Only 'amd' and 'system' modules are supported alongside --out
body: <p>When building typescript in VSCode, I get the following error:</p>
  
  <blockquote>
    <p>error TS6082: Only 'amd' and 'system' modules are supported alongside
    --out.</p>
  </blockquote>
  
  <p>My settings are as follows:</p>
  
  <p><strong>tsconfig.json</strong></p>
  
  <pre><code>{
      "compilerOptions": {
          "target": "ES5",
          "module": "commonjs",
          "out": "current/game.js",
          "removeComments": true,
          "sourceMap": false
      }
  }
  </code></pre>
  
  <p><strong>.vscode/tasks.json:</strong></p>
  
  <pre><code>{
      "version": "0.1.0",
  
      // The command is tsc. Assumes that tsc has been installed using npm install -g typescript
      "command": "tsc",
  
      // The command is a shell script
      "isShellCommand": true,
  
      // Show the output window only if unrecognized errors occur.
      "showOutput": "silent",
  
      // args is the HelloWorld program to compile.
      "args": [],
  
      // use the standard tsc problem matcher to find compile problems
      // in the output.
      "problemMatcher": "$tsc"
  }
  </code></pre>
  
  <p>Despite the error, the game.js file does get created and runs properly.</p>
  
  <p>Anyone have any thoughts about what might cause this error?</p>
