VSC 调试器抛出语法错误：无法在模块外部使用 import 语句

Question

在最近更新 Visual Studio Code 之前，我能够使用此launch.json配置调试用 TypeScript 编写的 Node.js 应用程序

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Debug API",
            "protocol": "inspector",
            "program": "${workspaceFolder}/apps/api/src/main.ts",
            "outFiles": ["${workspaceFolder}/dist/apps/api/main.js"],
            "sourceMaps": true
        }
    ]
}

但现在我收到这个错误

import * as express from 'express';
^^^^^^

SyntaxError: Cannot use import statement outside a module

知道如何解决这个问题吗？或者至少让它工作，同时 VSC 团队在其 GitHub 上提供答案https://github.com/microsoft/vscode/issues/102834

Answer 1

您可以执行以下操作：

1. 在 中添加（如果尚不存在）构建步骤package.json，如下所示；

   "ci-build": "npx tsc",
   

2. 我有tsconfig.json以下选项；

   "compilerOptions": {
       "outDir": "dist",
       "rootDir": "src",
       "module": "commonjs"
       "sourceMap": true,
       "lib": ["esnext", "dom"],
       "strict": true,
       "esModuleInterop": true,
       "target": "es2017"
   }
   

   注意：确保sourceMap将true

3. 我的launch.json样子是这样的；

   {
       "type": "node",
       "request": "launch",
       "name": "Build Project",
       "program": "${workspaceFolder}/src/index.ts",
       "preLaunchTask": "npm: ci-build",
       "sourceMaps": true,
       "smartStep": true,
       "internalConsoleOptions": "openOnSessionStart",
       "outFiles": ["${workspaceFolder}/dist/**/*.js"]
   }

根据此 github 问题的评论，VSC Team 提供了针对 Visual Studio Code 1.48 版本的修复：

{
    "type": "node",
    "request": "launch",
    "name": "Debug launcher",
    "protocol": "inspector",
    "program": "${workspaceFolder}/apps/launcher/src/main.ts",
    "outFiles": ["${workspaceFolder}/dist/**/*.js"],
    "sourceMaps": true
}
