如何从apt安装Python 3.4.5?
我已经安装了Python 3.5。我以前从源代码安装了Python 3.4,并设法以某种方式将其卸载。现在,如果我尝试通过安装Python 3.4 apt-get install python3.4,它将返回 Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'libpython3.4-minimal' for regex 'python3.4' 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. 直接执行也python3.4 --version不起作用。我该怎么办?
