fsPromises.rm(path[, options])

删除文件和目录（在标准 POSIX rm 实用工具上建模）。

• path <string> | <Buffer> | <URL>
• options <Object>
  • force <boolean> When true, exceptions will be ignored if path does not exist. Default: false.
  • maxRetries <integer> If an EBUSY, EMFILE, ENFILE, ENOTEMPTY, or EPERM error is encountered, Node.js will retry the operation with a linear backoff wait of retryDelay milliseconds longer on each try. This option represents the number of retries. This option is ignored if the recursive option is not true. Default: 0.
  • recursive <boolean> If true, perform a recursive directory removal. In recursive mode operations are retried on failure. Default: false.
  • retryDelay <integer> The amount of time in milliseconds to wait between retries. This option is ignored if the recursive option is not true. Default: 100.
• Returns: <Promise> Fulfills with undefined upon success.

Removes files and directories (modeled on the standard POSIX rm utility).
