--enable-source-maps
启用 源映射 支持堆栈跟踪。
🌐 Enable Source Map support for stack traces.
当使用像 TypeScript 这样的转译器时，应用抛出的堆栈跟踪会引用转译后的代码，而不是原始源代码位置。--enable-source-maps 启用源映射的缓存，并尽最大努力报告相对于原始源文件的堆栈跟踪。
🌐 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.
重写 Error.prepareStackTrace 可能会阻止 --enable-source-maps 修改堆栈跟踪。在重写函数中调用并返回原始 Error.prepareStackTrace 的结果，以便使用源映射修改堆栈跟踪。
🌐 Overriding Error.prepareStackTrace may prevent --enable-source-maps from
modifying the stack trace. Call and return the results of the original
Error.prepareStackTrace in the overriding function to modify the stack trace
with source maps.
const originalPrepareStackTrace = Error.prepareStackTrace;
Error.prepareStackTrace = (error, trace) => {
// Modify error and trace and format stack trace with
// original Error.prepareStackTrace.
return originalPrepareStackTrace(error, trace);
}; 注意，启用源映射可能会在访问 Error.stack 时增加应用的延迟。如果你的应用中频繁访问 Error.stack，请考虑 --enable-source-maps 的性能影响。
🌐 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.
