【问题讨论】：
【参考方案1】：在寻找vscode拒绝附加断点的原因后，我找到了原因以及如何解决它。
好吧，使用launch.json 设置"trace": "verboser", 我找到了这条踪迹：
SourceMaps.setBP: /Users/gilsoncav/dev-js/emails-tags-input/src/emails-input.ts can't be resolved to a loaded script. It may just not be loaded yet.
Paths.setBP: No target url cached yet for client path: /Users/gilsoncav/dev-js/emails-tags-input/src/emails-input.ts.
我去了 Chrome DevTools 来检查 SourceMap 在那边的情况...
请注意，源映射脚本的路径是 webpack://EmailsInput/./...，这就是为什么 launch.json 中的以下传统设置不起作用
"sourceMapPathOverrides":
"webpack:///./*": "$workspaceFolder/*"
因此，解决方法是将其设置为：
"sourceMapPathOverrides":
"webpack://EmailsInput/./*": "$workspaceFolder/*"
为什么有这个该死的EmailsInput？我发现罪魁祸首是我在 webpack.config.js 中使用的 library 设置：
...
output:
filename: 'emails-input.js',
// Setting webpack to generate the library with a global variable as
// the spec of the test is suggesting
library: 'EmailsInput',
libraryTarget: 'var',
libraryExport: 'default',
globalObject: 'this',
path: path.resolve(__dirname, 'dist'),
,
...
【讨论】：
感谢详细的跟踪提示。检查了它吐出的路径并最终使用了类似的东西："webpack://$workspaceFolderBasename/*": "$workspaceFolder/*"以上是关于使用 VSCODE 进行调试无法在 Webpack + Typescript + 无框架中工作的主要内容，如果未能解决你的问题，请参考以下文章
