我在Win 10下使用Msys2 portable.我有2个python 3.8安装。原来的问题是问是否是这样的,现在我确定是这样的,所以暂时我想处理他们的维护。我现在确定是这样,所以目前我想处理他们的维护。
我还发了另一个相关问题 Msys2:在两个python安装中的读线。
我在下面贴出两方面的信息。
我的问题是。
Can they interfere with each other? If so, what stepsconfiguration should I deal with? (PYTHONPATH
, site-packages
等)。)
在不破坏其他的情况下,删除其中任何一个都是安全的吗?下面的依赖关系在我看来这意味着没有风险,但我不确定这是否有足够的信息来回答这个问题。
哪一个是最好的保留?numpy
, pandas
,gcc-toolchain和通过Eclipse CDT调试器,以及其他一些包。
PS1:这是在python2之外,同样的问题也适用于它。
PS2:我觉得很奇怪,即使版本都是3.8.2,可用的子版本也不完全一样。
PS3:这两个python很有可能是由主角的升级而来。这出,python 3.8 (3.8.1之前)升级为 mingw-w64-x86_64-python 3.8.2-2
和python 3.7升级到 python 3.8.2-1
.

提供python2的包
$ pacman -Sl | grep "python2 " | grep "installed"

msys python2 2.7.18-1 [installed: 2.7.17-1]
我在MSYS2 shell中使用了2个不同版本的Python(版本2+3)。
我所做的是下面的。
PATH
环境变量,所以如果有东西需要Python,就会失败。PATH=<python_path>:$PATH
到需要它的命令中(例如 PATH=/D/Prog/Python/WinPython-64bit-2.7.13.1Zero/python-2.7.13.amd64:$PATH make
),或者如果命令支持在环境中设置PYTHON,我就会在前面加上 PYTHON=<python_path>/python.exe
前的命令。在某些情况下 Makefile
或 configure
接受 PYTHON
变量,也可以附加 PYTHON=<python_path>/python.exe
后面的命令。PYTHONPATH
变量 PYTHONPATH=<python_path>/Lib/site-packages
)这对我来说很好用,总是迫使我选择我使用的Python。
