Question

当我使用python 3.8时，python pandas模块曾经可以工作。我已经升级到python 3.9，它停止工作了。我尝试安装它，但是出现错误。

这是我的python版本：

Python 3.9.0a1

我正在尝试在Windows 10上安装pandas python模块。但是当我收到此错误时：

pip install pandas
Collecting pandas

pip :   ERROR: Command errored out with exit status 1:

这是完整的错误：https://pastebin.com/dEuEkmGE

我确实安装了numpy和cython：
