此函数启用或禁用 源映射 v3 对堆栈跟踪的支持。

它提供与使用命令行选项 --enable-source-maps 启动 Node.js 进程相同的功能。

只有在启用源映射后加载的 JavaScript 文件中的源映射才会被解析和加载。

¥Only source maps in JavaScript files that are loaded after source maps has been enabled will be parsed and loaded.

这意味着使用选项 { nodeModules: true, generatedCode: true } 调用 module.setSourceMapsSupport()。

¥This implies calling module.setSourceMapsSupport() with an option { nodeModules: true, generatedCode: true }.
