Question

在最近更新Visual Studio Code之前，我可以使用此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
        }
    ]
}

但是现在我遇到了这个错误

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

SyntaxError: Cannot use import statement outside a module

关于如何解决此问题的任何想法？或者至少在VSC团队在其GitHub https://github.com/microsoft/vscode/issues/102834

上提供答案的同时使其工作

关于此github问题，VSC团队已为1.48版VSC-> https://github.com/microsoft/vscode/issues/102873#issuecomment-674999289

提供了修复程序

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

就我而言，这 blog 有助于解决问题。总之；

在 package.json 中添加（如果尚不存在）构建步骤，如下所示；

"ci-build": "npx tsc",

我在 tsconfig.json 中有以下选项；

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

在这里将 sourceMap 设置为 true 对我来说是缺失的。

我的 launch.json 看起来像这样；

{
    "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"]
}

VSC调试器引发SyntaxError：无法在模块外部使用import语句
