创建同步进程


child_process.spawnSync()child_process.execSync()child_process.execFileSync() 方法是同步的,且会阻塞 Node.js 事件循环、暂停执行任何其他代码,直到衍生的进程退出。

阻塞这些调用对于简化通用脚本任务和简化启动时应用程序配置的加载或处理非常有用。

The child_process.spawnSync(), child_process.execSync(), and child_process.execFileSync() methods are synchronous and WILL block the Node.js event loop, pausing execution of any additional code until the spawned process exits.

Blocking calls like these are mostly useful for simplifying general-purpose scripting tasks and for simplifying the loading/processing of application configuration at startup.
