python and python2.7 runs different python instances

Question

This is the output when I write whereis python2.7

python2.7: /usr/local/bin/python2.7 /usr/local/lib/python2.7 /opt/python2.7.1/bin/python2.7

Version of python under /usr/local/ is python2.7.2 and version of python under /opt/python/2.7.1 is python2.7.1 as you see.

When I write python it runs python2.7.1 because I changed the bash_profile. But When I write python2.7 it runs python2.7.2.

I would like totally remove the python2.7.2 which is under the /usr/local/ and use the binary under /opt/python2.7.1.

How can I solve this problem?

Note: It is a CentOS5 server and python2.4 is already installed as you consider.

your PATH is mixed up, do the following:

export PATH=/opt/python2.7.1/bin:$PATH
export LD_LIBRARY_PATH=/opt/python2.7.1/lib:$LD_LIBRARY_PATH

Should I do it on my .bash_profile also? or just doing once will be okay?

You should add it to your .bash_profile. Doing it once will work for your current session only.

PATH=$PATH:$HOME/bin #export PATH alias python='/opt/python2.7.1/bin/python' alias python2.7.='/opt/python2.7.1/bin/python' alias python2.7.1='/opt/python2.7.1/bin/python' export PATH=$PATH:/opt/python2.7.1/bin export LD_LIBRARY_PATH=/opt/python2.7.1/lib:$LD_LIBRARY_PATH

Sorry for structure of my comment above but although I added it still runs python2.7.2 when I wrote python2.7

remove your aliases. and your python PATH export is wrong. You add /opt/python2.7.1/bin before $PATH

You could simply try using an alias in ~/.bash_aliases so that you always refer to the python you want inside your terminal and user instance. I would not recommend removing python2.7.2 as it might cause dependency issues

Like this

alias python2.7 = "/path/to/python2.7.1/"

alias is not enough. python has library dependencies as well.
