v15.11.0	此 API 不再是实验的。
v12.12.0	新增于: v12.12.0

启用 Source Map v3 对堆栈跟踪的支持。

当使用转译器（例如 TypeScript）时，应用程序抛出的堆栈跟踪会引用转译后的代码，而不是原始的源位置。 --enable-source-maps 启用源映射缓存并尽最大努力报告相对于原始源文件的堆栈跟踪。

覆盖 Error.prepareStackTrace 可防止 --enable-source-maps 修改堆栈跟踪。

注意，启用源映射会在访问 Error.stack 时给您的应用程序引入延迟。如果您在应用程序中频繁访问 Error.stack，则考虑 --enable-source-maps 的性能影响

Enable Source Map v3 support for stack traces.

When using a transpiler, such as TypeScript, stack traces thrown by an application reference the transpiled code, not the original source position. --enable-source-maps enables caching of Source Maps and makes a best effort to report stack traces relative to the original source file.

Overriding Error.prepareStackTrace prevents --enable-source-maps from modifying the stack trace.

Note, enabling source maps can introduce latency to your application when Error.stack is accessed. If you access Error.stack frequently in your application, take into account the performance implications of --enable-source-maps.
