Sentinel无法读取nacos的流控配置，提示Caused by: java.lang.NoClassDefFoundError: com/alibaba/csp/sentinel/datasou

今天在学到用nacos配置流控策略并发布到sentinel时，我明明按照视频教学中的步骤进行的，结果死活没法在sentinel的流控策略中找到nacos上配置的，并且

cloud:
    sentinel:
      transport:
        dashboard: xxxxxx:8849
        port: 8719
      datasource:
        flows: 在此加上这个名称后就直接报错，无法运行
          nacos:
            server-addr: xxxx:8848
            username: nacos
            password: nacos
            data-id: springcloud-provider-dept-nacos-flow
            group-id: DEFAULT_GROUP
            data-type: json
            rule-type: flow

于是我就上网查找各种原因，但都没有效果。

最后...我把版本降了一下，果然啊，以下2021.1的依赖，都是从2021.0.1.0降下来的。

看来每次都无脑用最新的依赖，会坑死人啊！！！

现在是凌晨3点，折磨了一天，终于能把程序跑通睡觉了，555~~~

楼主还是个小菜鸡，有哪里说的不对了还请大佬们海涵
