fs.rm(path[, options], callback)
path<string> | <Buffer> | <URL>options<Object>force<boolean> 当为true时,如果path不存在,则异常将被忽略。 默认值:false。maxRetries<integer> 如果遇到EBUSY、EMFILE、ENFILE、ENOTEMPTY或EPERM错误,Node.js 将在每次尝试时以retryDelay毫秒的线性退避等待时间重试该操作。 此选项表示重试次数。 如果recursive选项不为true,则忽略此选项。 默认值:0。recursive<boolean> 如果为true,则执行递归删除。 在递归模式下,操作将在失败时重试。 默认值:false。retryDelay<integer> 重试之间等待的时间(以毫秒为单位)。 如果recursive选项不为true,则忽略此选项。 默认值:100。
callback<Function>err<Error>
异步地删除文件和目录(以标准 POSIX rm 实用工具为模型)。
除了可能的异常之外,没有为完成回调提供任何参数。
path<string> | <Buffer> | <URL>options<Object>force<boolean> Whentrue, exceptions will be ignored ifpathdoes not exist. Default:false.maxRetries<integer> If anEBUSY,EMFILE,ENFILE,ENOTEMPTY, orEPERMerror is encountered, Node.js will retry the operation with a linear backoff wait ofretryDelaymilliseconds longer on each try. This option represents the number of retries. This option is ignored if therecursiveoption is nottrue. Default:0.recursive<boolean> Iftrue, perform a recursive 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 therecursiveoption is nottrue. Default:100.
callback<Function>err<Error>
Asynchronously removes files and directories (modeled on the standard POSIX rm
utility). No arguments other than a possible exception are given to the
completion callback.
