如何在Visual Studio代码中调试打字稿文件

使用Visual Studio代码的0.3版，我不确定如何启用Sourcemap和调试ts文件

我收到以下错误 can't launch program '/Projects/app-server/server.ts'; enabling source maps might help

如何启用Sourcemap和TypeScript调试。在我的Sourcemap中设置为true

tsconfig.json

{
    "compilerOptions": {
        "target": "ES5",
        "module": "commonjs",
        "sourceMap": true
    }
}

launch.json

{
    "version": "0.1.0",
    // List of configurations. Add new configurations or edit existing ones.  
    // ONLY "node" and "mono" are supported, change "type" to switch.
    "configurations": [
        {
            // Name of configuration; appears in the launch configuration drop down menu.
            "name": "Launch server.ts",
            // Type of configuration. Possible values: "node", "mono".
            "type": "node",
            // Workspace relative or absolute path to the program.
            "program": "server.ts",
            // Automatically stop program after launch.
            "stopOnEntry": true,
            // Command line arguments passed to the program.
            "args": [],
            // Workspace relative or absolute path to the working directory of the program being debugged. Default is the current workspace.
            "cwd": ".",
            // Workspace relative or absolute path to the runtime executable to be used. Default is the runtime executable on the PATH.
            "runtimeExecutable": null,
            // Environment variables passed to the program.
            "env": { }
        }, 
        {
            "name": "Attach",
            "type": "node",
            // TCP/IP address. Default is "localhost".
            "address": "localhost",
            // Port to attach to.
            "port": 5858
        }
    ]
}
