Today, I was trying to install an application on my CentOS 6.6 system which required Python >= 2.7, but there are Python 2.6 installed, which we can’t remove as other applications depend on it. This tutorial will help you to install Python 2.7 without removing older versions.
Step 1 – Install GCC
Firstly make sure that you have gcc package installed on your system. Use following command to install gcc if you don’t have it installed.
# yum install gcc
Step 2 – Download Python 2.7
Download Python using following command from python official site. You can also download latest version in place of specified below.
# cd /usr/src # wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz
Step 3 – Extract Archive and Compile
Use below set of commands to extract Python source code and compile it on your system using altinstall.
# tar xzf Python-2.7.13.tgz # cd Python-2.7.13 # ./configure # make altinstall
Step 4 – Check the Python Version
Check the latest version installed of python using below command
python2.7 -VPython 2.7.13
Step 5 – Install PIP
Finally, install the PIP for the installed Python version.
$ curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py" $ python2.7 get-pip.py
