如何在VScode中設置打字稿？

我獨自跟着VS Code typescript配置。如何在VScode中設置打字稿？

https://code.visualstudio.com/Docs/languages/typescript

我安裝我的tsconfig.json像

{ 
    "compilerOptions": { 
     "module": "system", 
     "noImplicitAny": true, 
     "removeComments": true, 
     "preserveConstEnums": true, 
     "outFile": "built/local/tsc.js", 
     "sourceMap": true 
    }, 
    "include": [ 
     "**/*" 
    ], 
    "exclude": [ 
     "node_modules", 
     "**/*.spec.ts" 
    ] 
}

，我的任務運行

{ 
    // See https://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": "always", 
    "problemMatcher": "$tsc" 
}

我的TS碼

class StartUp { 
    public static main(): number { 
     console.log('Helle Workd'); 
     return 5; 
    } 
} 
console.log('test'); 

StartUp.main();

對於一些reaso n，當我按下cmd + shift + B（build）時，在輸出窗口中看不到任何輸出。我確實看到如下錯誤：

hello.ts(8,1): error TS2304: Cannot find name 'ddd'.

如果我在代碼中隨機添加ddd字符串。

有人可以幫我解決這個問題嗎？非常感謝！

是生成的文件好嗎？也許你可以運行「tsc -p」。在控制檯。如果沒有錯誤，命令將不會輸出。 – Yuan

命令「tsc -p。」在編譯時不會輸出任何錯誤，並且會生成所有已編譯的JavaScript/SourceMap文件，因此您無法在VSCode的輸出窗口中看到任何文件。只需在控制檯中鍵入並運行該命令即可。

您可以添加選項「--diagnostics」以使命令輸出一些信息。

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

輸出：
