我在 Win 10 下使用 Msys2 便携版。我有 2 个 python 3.8 安装。原来的问题是这样问的。我现在确定它是，所以我暂时想处理他们的维护。
我还发布了另一个相关问题Msys2: readline in two python installations
我在下面发布两者的信息。
我的问题是：
他们能互相干扰吗？如果是这样，我应该处理哪些步骤/配置？(
PYTHONPATH,site-packages, 等)在不破坏另一个的情况下移除其中任何一个是否安全？在我看来，下面的依赖项似乎没有风险，但我不确定是否有足够的信息来回答这个问题。
哪个是最好保留的？我的意思是通过 Eclipse CDT 使用
numpy,pandas, gcc-toolchain 和调试器，以及其他一些包。
PS1：这是对 python2 的补充，同样的问题也适用。
PS2：我觉得奇怪的是可用的子版本并不完全相同，即使版本都是 3.8.2。
PS3：这两条蟒蛇很可能是本次“剧”主角的升级，python 3.8（之前的3.8.1）升级到mingw-w64-x86_64-python 3.8.2-2python 3.7升级到python 3.8.2-1。
