为Python 2.6安装熊猫

Question

Currently I have two versions of python (2.6 and 2.7) on my unix machine.

Python 2.7 has already got pandas installed for it but 2.6 doesn't have. So, I'm trying to install pandas specifically for python2.6 as my production environment has got ONLY python 2.6 and I cannot upgrade that at this point of time. When I tried installing it using the below command, it says "Requirement already satisfied" pointing to python2.7 and nothing got added to python 2.6.

@user  pip install pandas
Requirement already satisfied: pandas in /usr/local/lib/python2.7/site-
packages
Requirement already satisfied: pytz>=2011k in 
            /usr/local/lib/python2.7/site-packages (from pandas)
Requirement already satisfied: numpy>=1.7.0 in 
            /usr/local/lib/python2.7/site-packages (from pandas)
Requirement already satisfied: python-dateutil in 
            /usr/local/lib/python2.7/site-packages (from pandas)
Requirement already satisfied: six>=1.5 in 
            /usr/local/lib/python2.7/site-packages (from python-dateutil-
            >pandas)

Please advice on how do I specifically install Pandas for Python2.6.

Assuming you installed Python 2.6 in the usual directory, you can just run

C:\Python26\Scripts\pip.exe

or go to that directory in a Command Prompt and run

.\pip.exe 

Oops. Just noticed you're on a UNIX box. But the result is the same. You must specify the full path to the pip you want, or go to the directory and run .\\pip

The other pip and python are in the system "path", the list of places that get searched for an executable. So, you have to tell the O/S exactly which pip you want to run. Otherwise, if you just say pip , it will find whichever one it can find in the system path.
