创建同步进程


child_process.spawnSync()child_process.execSync()child_process.execFileSync() 是同步的,且会阻塞 Node.js 事件循环直到衍生的进程退出。

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.
