@JoinQuant-Supercritical 请问这是常见的问题吗？

@Elen 算是吧，有时自己的环境变了，就会出现这样的问题

你好！按照你的建议，我尝试重新安装之后，出现了这样的错误，请问应该怎么办？

@Elen 根据报错最后一行提示，升级pip；还有以管理员权限打开及安装。

@JoinQuant-Supercritical 非常感谢你的帮助！

@TianNG 先安装anaconda，然后在anaconda中安装jqdatasdk试试

@nicknys 把anaconda卸载了重新安装的看看

jqdatasdk 还是只支持pandas 0.25以下版本吗？ pandas的官方版本已经是1.1了。 安装jqdatasdk 1.8是会删除已安装的高版本的pandas，重新安装0.25版的pandas ``` Requirement already satisfied: pandas< =0.25.3,>=0.16.2 ```

@如如不动 0.25.3及其以下的,1及以上的后期支持会有相关说明的，pandas的不同版本变化太大了，为了系统的稳定性，我们目前不会只要有新版本就立即更新支持的。

@TianNG 已经解决，多谢。

@JoinQuant-Supercritical pandas 1.0已经出来很久了 希望能早点支持 很多包依赖已经更新到1.0了 没法在同一个environment下使用

@siaosing pandas不同版本的兼容性太差了...

请教一下，这个和策略研究里面的策略列表里面的一样么？

@GoodThinker 不一样，那个是官网的回测及模拟交易。这个jqdatasdk只是一个数据接口，在本地使用的，不支持回测和模拟交易。

@JoinQuant-Supercritical 那意义在哪里呢？没搞懂；只是在本地获取数据吗？

@GoodThinker 自己获取实时数据，自己在本地搭建回测实盘框架之类的。不过您觉得这些没有意义的话，可以在官网使用的。
