存在的问题

可能会报错redis没有RedisTimeSeries扩展模块，详细信息可以参考redis官网https://redis.io/docs/latest/develop/data-types/timeseries/
也可以参考如下：
https://blog.csdn.net/LinkSLA/article/details/123040789

查看redis中是否有时间序列数据库模块可以参考如下代码：

python"># 连接到Redis
r = redis.StrictRedis(host='localhost', password="xxxx", port=63790, db=0)# 获取Redis的信息
info = r.info()
print(info)
# 检查是否加载了时间序列数据库模块
if 'redis_modules' in info and 'name' in info['redis_modules']:for module in info['redis_modules']:if module['name'] == 'timeseries':print("Redis Time Series Database module is enabled.")
else:print("Redis Time Series Database module is not enabled.")
