1.用anaconda创建虚拟环境
(base) C:\Users\Administrator>conda -V
conda 24.5.0(base) C:\Users\Administrator>conda create -n appenv python

3.打开pycharm
4.新建工程，注意第五步最为重要。第六步选择实际想用的环境。
进入系统可见成功。以上是新建工程时的方法。
下面演示如何在已有工程中修改这个环境
点小三角号：
注意三是点小三角号
比如我使用的是最后一个。
等待更新：早知不选最后一个，太太大了。只是演示而已。
重启pytharm ，正常。
cs上大多是修改已有工程的，并且都说得不明白，我个人觉得。所以我的这个应该是最好的。欢迎点赞，让更多人看到。
