typescript - "Cannot launch program ' E :\typescriptBasis\main. ts ' because corresponding JavaScript cannot be found."

Question

我正在 Windows 10 中使用 visual studio code 学习 typescript ，但我在运行简单程序时遇到错误。
“无法启动程序‘E:\typescriptBasis\main.ts’，因为找不到相应的 JavaScript。”因此我无法调试代码。

我已经安装了nodejs v10.2.1版本
我已经安装了npm v5.6.0版本
我已经全局安装了 typescript v2.8.3
我已经安装了Visual sudio code v1.23.1

launch.json 文件

我让它和下面的一起工作launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch Program",
            "preLaunchTask": "TSC",
            "program": "${file}",
            "outFiles": [
                "${workspaceFolder}/**/*.js"
            ]
        }
    ]
}

tsconfig.json:

{
  "compilerOptions": {
    "target": "esnext",        
    "module": "commonjs",      
    "allowJs": false,          
    "sourceMap": true,         
    "strict": true,            
    "noUnusedLocals": true,    
    "noUnusedParameters": true,
    "noImplicitReturns": true, 
    "esModuleInterop": true    
  }
}

和tasks.json:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "TSC",
            "type": "typescript",
            "tsconfig": "tsconfig.json",
            "problemMatcher": [
                "$tsc"
            ]
        }
    ]
}

我当前的 VS Code 版本是 1.28.2
