Python 错误：找不到满足pandas要求的版本（来自版本：），找不到pandas的匹配分发

我是PyCharm的新手，想在我的项目中安装pandas。 因此，我在PyCharm的终端中使用了以下命令（一个接一个，因为第一个命令不起作用）

>pip install pandas
>python -m pip install pandas

他们两个我都犯了同样的错误

错误：

现在如何安装熊猫？请帮忙

操作系统：Windows 10
Python版本：Python 3.7.6

pip版本：pip 19.0.3因此，我的系统安装了Anaconda，在创建项目时，我忘了将“基本解释器”从Conda更改为普通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东西的原因

为什么不在项目中使用Conda？为什么不在项目中使用Conda？
