默认python/usr/bin/python而不是/usr/local/bin/python [英] Default python /usr/bin/python instead of /usr/local/bin/python

问题描述

我在CentOS框中同时安装了python2.6和python2.7.python2.6安装在/usr/bin/python 上，我已经从源代码在位置/usr/local/bin/python

I have both python2.6 and python2.7 installed in my CentOS box. python2.6 is installed at /usr/bin/python and i have installed python2.7 from source at location /usr/local/bin/python

安装后，我的默认python更改为python2.7而不是/usr/bin 上的pythn2.6，我想在python2.6下使用/usr/bin/python .我已经尝试按照已经不起作用的方法进行操作.

after the installation my default python is changed to python2.7 instead of pythn2.6 at /usr/bin, I want to use python 2.6 at /usr/bin/python. I have tried following things already nothing worked.

1. 我创建了symlink并将其指向/usr/bin
上的python 2.6
2. 我已经在.bash_profile中修改了我的默认python路径，但这仍然行不通

请让我知道如何安装python 2.7和2.6，并将python 2.6作为默认版本.我在arch Linux机器上也有同样的东西，但是在centos机器上却不起作用.

Please let me know how can i have python 2.7 installed along with 2.6 installed and python 2.6 as my default version. I have the same thing working with my arch linux box, but this doesn't work with my centos box.

附加我的.bash_profile，

Attaching my .bash_profile,

# .bash_profile

export _BASH_PROFILE=1

# Get the aliases and functions
if [ -z "$_BASHRC" ]; then
        . ~/.bashrc
fi

unset _BASH_PROFILE

# User specific environment and startup programs

PATH=$PATH:$HOME/bin
BASH_ENV=$HOME/.bashrc
USERNAME=""

export USERNAME BASH_ENV PATH

export user=$(/usr/bin/whoami)
export WK_PORT=8086
export WK_PATH=ADC

# For DEV accounts change PYDOC_PORT value to 7400 + webkit number. For
# example WK23 would be port number 7423
export PYDOC_PORT=7464


alias serve="python -m SimpleHTTPServer"


unset _BASH_PROFILE

# User specific environment and startup programs

PATH=$PATH:$HOME/bin
BASH_ENV=$HOME/.bashrc
USERNAME=""

export USERNAME BASH_ENV PATH

export user=$(/usr/bin/whoami)
export WK_PORT=8086
export WK_PATH=ADC

# For DEV accounts change PYDOC_PORT value to 7400 + webkit number. For
# example WK23 would be port number 7423
export PYDOC_PORT=7464


alias serve="python -m SimpleHTTPServer"


PYTHONPATH="$PYTHONPATH:/usr/bin/python"

推荐答案

我遇到了同样的问题.以下命令对其进行了修复:

I had the same problem. The following command fixed it:

sudo ln -sf /usr/bin/python /usr/local/bin/python

这将从/usr/local/bin/python -> /usr/bin/python 建立符号链接.从此处

This will make a symbolic link from /usr/local/bin/python --> /usr/bin/python. Referred from here
