连接到 Node 调试器 (Next.js) 时出现“无法读取源映射”错误

Question

我正在按照Next.js 调试文档来设置本地调试环境。

“第 1 步：在调试模式下启动 Next.js”工作正常：

> cross-env NODE_OPTIONS='--inspect' next dev

Debugger listening on ws://127.0.0.1:9229/e4bb955d-e3b2-4849-b6e7-0248e6a3d53e
For help, see: https://nodejs.org/en/docs/inspector
Loaded env from C:\Users\markj\workspace\my-app\.env.local
ready - started server on http://localhost:3000
info  - Using external babel configuration from C:\Users\markj\workspace\my-app\babel.config.js
event - compiled successfully

但在“第 2 步：连接到调试器”中，我在 VSCode 调试控制台中收到以下错误：

Could not read source map for file:///C:/Users/markj/workspace/my-app/node_modules/next/dist/compiled/path-to-regexp/index.js: ENOENT: no such file or directory, open 'c:\Users\markj\workspace\my-app\node_modules\next\dist\compiled\path-to-regexp\index.js.map'

毫不奇怪，当我尝试附加断点时出现这些错误，它显示“未绑定断点”。

环境：

• Windows 10.0.19042
• Node.js 12.20.0
• Next.js 10.0.2
• VSCode 1.51.1

非常感谢任何帮助或想法！

这本质上是由 VSCode 调试文件引起的，它不应该尝试调试，即 node_modules。这里和这里有一些关于这个问题的 github 问题。我发现很有用。本质上，解决方法是阻止 VSCode 关心这些文件，您可以通过设置"type":"pwa-node"并添加以下内容来完成此操作：

"resolveSourceMapLocations": [
    "${workspaceFolder}/",
    "!/node_modules/**"
],

给你的launch.json下.vscode
