我使用的是Win 10下的Msys2便携。我有2个python3.8安装。原来的问题是,是否是这样。我现在肯定是这样,所以暂时我想处理他们的维修问题。
我还发布了另一个相关的问题Msys2: readline in two python installations
我在下面这两种信息上张贴。
我的问题是:
,
PYTHONPATH
,site-packages
等)numpy
、pandas
、gcc工具链和调试器。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subversions并不完全相同,即使版本都是3.8.2。
PS3:这两个蟒蛇很可能是从this "play"的主要角色升级的,python3.8 (3.8.1之前)升级到mingw-w64-x86_64-python 3.8.2-2
,python3.7升级到python 3.8.2-1
。

我在MSYS2 shell中使用了2个Python不同版本(版本2+ 3)。
我要做的是:
PATH
环境变量中,因此,如果需要Python,它就会失败。当需要Python时,我会将PATH=<python_path>:$PATH
先于需要它的命令(例如PATH=/D/Prog/Python/WinPython-64bit-2.7.13.1Zero/python-2.7.13.amd64:$PATH make
),或者如果命令支持在命令之前的环境中设置Python,则使用Makefile
或configure
接受PYTHON
变量,也可能在命令之后追加PYTHON=<python_path>/python.exe
。这对我来说很好,并且总是迫使我选择使用哪一个Python。
