我有一个从 Yeoman 脚手架生成的项目，使用了generator-express-no-stress-typescript 模板。我需要调试它，即“逐步执行typescript代码”，并使用 Visual Studio Code（不，console.log()对我来说不够用）。
根据文档，我只需要输入以下命令：
npm run dev:debug
然后附加VSCode。问题在于：如果这样做，VSCode 无法绑定断点。如果我使调试器停止在第一行执行 ("stopOnEntry": true)，它会停在生成的 JavaScript 代码上而不是源 TypeScript 代码上，但是选项卡标题中的文件名显示为 "index.ts"（不是 .js），并且以斜体字显示。
这是 package.json 中 dev:debug 脚本目标：
"dev:debug": "nodemon --exec \"node -r ts-node/register --inspect-brk\" server/index.ts | pino-pretty",
这是我的launch.json文件中与附件(Attach)相关的配置：
{
"name": "Debug (Attach)",
"port": 9229,
"request": "attach",
"cwd": "${workspaceFolder}",
"sourceMaps": true,
"skipFiles": ["<node_internals>/**"],
"type": "node",
// "outFiles": ["${workspaceFolder}/dist/**/*.js"],
},
由于这种方法无效，我尝试了一些其他的教程，其中一个（我不记得是哪一个了）让我在launch.json中加入以下配置:
{
"name": "Run and debug",
"program": "${workspaceFolder}/server/index.ts",
"request": "launch",
"skipFiles": [
"<node_internals>/**"
],
"type": "node",
// "outFiles": ["${workspaceFolder}/dist/**/*.js"],
"runtimeArgs": ["-r", "ts-node/register", "--preserve-symlinks"],
"runtimeExecutable": "node",
"args": ["--inspect", "${workspaceFolder}/server/index.ts"],
"cwd": "${workspaceFolder}",
}
一开始看起来很有前途，但后来我尝试时却发现它在调试代码时跳过了TS而是进入了JS中，就像上面的“Debug (Attach)”配置一样。
下面是调试器用于追踪执行的生成JS代码。请注意，它在末尾的注释中包含了源映射。

我解码了base64的sourcemap，它似乎包含了正确的路径到我的源代码，甚至还有源代码的一个副本。

这是我的tsconfig.json，以防有所需要：

我已经搭建了一个新的最小化范例 generator-express-no-stress-typescript 项目，遵循文档中的步骤。例如：
$ npm install -g yo generator-express-no-stress
$ yo express-no-stress ts-debug-test
当被问及在“Swagger 2”和“OpenAPI 3”之间进行选择时，选择“OpenAPI 3”，这是我第一次构建真实项目时所做的选择。如果您需要一个展示问题的最小化示例，也可以这样做，或者您可以在GitHub上找到我的示例。我只添加了我的launch.json文件，您只需在代码的第一行设置断点即可。
现在我不知道下一步该怎么做才能调试我的代码...有什么提示吗？
nodemon吗？ - beautifulcoder
