--pending-deprecation

触发挂起的弃用警告。

挂起的弃用通常与运行时弃用相同，但值得注意的是，它们默认关闭关闭，除非设置了 --pending-deprecation 命令行标志或 NODE_PENDING_DEPRECATION=1 环境变量，否则不会触发。 待弃用用于提供一种选择性的"早期警告"机制，开发者可以利用该机制来检测弃用的 API 的使用情况。

Emit pending deprecation warnings.

Pending deprecations are generally identical to a runtime deprecation with the notable exception that they are turned off by default and will not be emitted unless either the --pending-deprecation command-line flag, or the NODE_PENDING_DEPRECATION=1 environment variable, is set. Pending deprecations are used to provide a kind of selective "early warning" mechanism that developers may leverage to detect deprecated API usage.
