错误：找不到满足熊猫要求的版本（来自版本：）找不到与熊猫匹配的发行版

Question

I'm new to PyCharm and wanted to install pandas in my project. So, I used the following commands(one by one because the first one didn't work) in the terminal of PyCharm to do it.

>pip install pandas
>python -m pip install pandas

I got the same errors for both of them.

ERROR :

How do I install pandas now? Please help.

因此，我的系统安装了 Anaconda，在创建项目时，我忘记将“基本解释器”从 Conda 更改为普通的 python.exe，这就是为什么我在使用 Anaconda 的 pip 时无法在其中安装任何内容。
