Python 2.7 – Installation Guide for Kali Linux 

Hi Geeks,

In this post, am going to show you how to install Python 2.7 in Kali Linux without any errors (Import error, bash: pip: command not found).

Python 2.7:

Python 2.7.2 was released on June 11th, 2011.

The Python 2.7 series is scheduled to be the last major version in the 2.x series before 2.x moves into an extended maintenance period. The 2.7 series contains many of the features that were first released in Python 3.1.

End of Python 2.7 :

Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won’t be maintained after that date. A future version of pip will drop support for Python 2.7.

Bugs:

Python 2.7 causes lot of bugs due to end of life.

ImportError: No module named ‘Package Name’

pip: command not found error in Kali Linux

 

Install Python2 :

Steps:

  • Prerequisites for Python
  • Download Python 2
  • Compile python source code.
  • Check python version.

Step 1 : Prerequisites for Python 2

You must want to install the following prerequisites on your system. Open a terminal and execute the following commands on your system for installing all the required dependencies.

mk007@linuxlia:~$ sudo apt-get update
mk007@linuxlia:~$ sudo apt-get install build-essential checkinstall
mk007@linuxlia:~$ sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev li

Step 2 : Download Python 2.7

Open a terminal and switch the directory to /usr/bin.

mk007@linuxlia:~$ cd /usr/src

Here run the following command for downloading python2 tgz packages.

mk007@linuxlia:~$ wget https://www.python.org/ftp/python/2.7.18/Python-2.7.18.tgz

Now extract the tgz packages by running the below command.

mk007@linuxlia:~$ sudo tar xzf Python-2.7.18.tgz

Step 3 : Compile Python Source

Use the following commands to compile Python source code on your system using altinstall.

mk007@linuxlia:~@ cd Python-2.7.18
mk007@linuxlia:~@ sudo ./configure --enable-optimizations
mk007@linuxlia:~@ sudo make altinstall
make altinstall command is used to prevent replacing the default python binary file /usr/bin/python.

Step 4 : Check Python Version

Check the version of python using the following command.

mk007@linuxlia:~@  python2.7 -V
Python 2.7.18
