如何在CentOS上将Python3.5.2设置为默认Python版本? [英] How to set Python3.5.2 as default Python version on CentOS?

问题描述

是否可以将CentOS 7上的Python 3.5.2设置为默认Python版本?目前，我已默认安装了Python 2.7，并分别安装了Python 3.5.2.

Is there a way to set the Python 3.5.2 as the default Python version on CentOS 7? currently, I have Python 2.7 installed as default and Python 3.5.2 installed separately.

我使用了以下命令

mv /usr/bin/python /usr/bin/python-old
sudo ln -fs /usr/bin/python3 /usr/bin/python

，但此后yum给出错误.

-bash: /usr/bin/yum: /usr/bin/python: bad interpreter: No such file or directory

我这里缺少什么吗?

注意:它与推荐答案

如果是

sudo ln -fs /usr/bin/python3.5 /usr/bin/python

不起作用(应该)

您可以使用以下命令将别名添加到您的/home/.bashrc中:

you could just add an alias into your /home/.bashrcwith this command:

alias python="/usr/bin/python3.5"

，如果这不起作用，则应仅使用虚拟环境.阅读此页面即可开始.

and if this does not work either you should just use virtual env. Read this page to get started.
