那么就没有办法使用 pandas-market-calendars 了吗？

pandas-market-calendars 4.3.3 requires pandas<2.0,>=1.1, but you have pandas 2.2.0 which is incompatible.

Answer 1

似乎在安装一堆软件包时（可能来自

requirements.txt

？），您获得了pandas的

旧

版本，但满足了

pandas-market-calendars

的依赖关系。然后你试图单独升级

pandas

并陷入冲突。

有时，正如 @corralien 所建议的，可以忽略这些版本要求，但在这种特殊情况下则不然。因此，在

pandas-market-calendars

适应当前

pandas

2.2.0 的重大变化之前，无法使用最新的

pandas along with 

pandas-market-calendars`。我会监视第二个库，因为它可能会升级。此外，您还可以归档或检查票据以查看重大变更是什么。
