我在 Win 10 下使用 Msys2 便携式。
我有 2 个 python 3.8 安装。最初的问题是问是否如此。我现在确定了，所以暂时我想处理他们的维护工作。
我还发布了另一个相关问题Msys2：两个 python 安装中的 readline
我在下面发布有关两者的信息。
我的问题是：
他们可以互相干扰吗？
如果是这样，我应该处理哪些步骤/配置？ （PYTHONPATH, site-packages, etc.)
删除其中任何一个而不破坏另一个是否安全？
在我看来，下面的依赖关系意味着没有风险，但我不确定是否有足够的信息来回答这个问题。
哪一个是最好保留的？
我的意思是使用numpy, pandas、gcc-toolchain 和通过 Eclipse CDT 的调试器，以及许多其他软件包。
PS1：
这是对 python2 的补充，同样的问题也适用于 python2。
PS2：
我觉得奇怪的是，可用的颠覆版本并不完全相同，即使版本都是 3.8.2。
PS3：
这两条蟒蛇很可能是主角的升级版这场“戏”，python 3.8（之前的3.8.1）升级到mingw-w64-x86_64-python 3.8.2-2和 python 3.7 升级到python 3.8.2-1.
