scrapy-redis 报错
redis.exceptions.ResponseError: Command # 2 (ZREMRANGEBYRANK xxxxxx:requests 0 0) of pipeline caused error:
MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands
that may modify the data set are disabled, because this instance is configured to report errors during writes
if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
