解决问题

A version of Python 3.8 (64- bit) is already at C:\Program Files\Python38\

We recommend that if you want Anaconda registered as your system Python, you unregister this Python first. If you reallyknow this is what you want, click OK, otherwise click cancel to continue.

NOTE: Anaconda 1.3 and earlier lacked an uninstall, ifyou are upgrading an old Anaconda, please delete the directory manually.

解决思路

Python 3.8(64位)的版本已经在C:\Program Files\Python38\

我们建议，如果您想将Anaconda注册为您的系统Python，请先取消注册此Python。如果你确实知道这是你想要的，点击确定，否则点击取消继续。

注:Anaconda 1.3及更早版本缺少卸载，如果您正在升级旧的Anaconda，请手动删除目录。

解决方法

系统检测到当前电脑上存在其它python编译器，如果的确需要将Anaconda默认的python设置为系统的python，那么就可以勾选当前按钮。
