问题描述

有没有办法将 Python 3.5.2 设置为 CentOS 7 上的默认 Python 版本?目前，我默认安装了 Python 2.7，并单独安装了 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

但在那之后 yum 给出了错误.

but after that yum gives the error.

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

这里有什么我遗漏的吗?

is there something I'm missing here?

注意:它与 Linux CentOS 7，如何设置Python2.7为默认Python版本?

解决方案

如果这样

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

不起作用(它应该)

您可以使用以下命令将别名添加到您的 /home/.bashrc:

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，您应该只使用虚拟环境.阅读此页面开始.

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