/usr/bin/env: ‘python’: No such file or directory

I am trying to install Gitlab Development Kit on Windows Ubuntu Bash.

$python3 output

Python 3.5.2 (default, Nov 17 2016, 17:05:23)[GCC 5.4.0 20160609] on linuxType "help", "copyright", "credits" or "license" for more information.>>>

$python output

The program 'python' can be found in the following packages: * python-minimal * python3Try: sudo apt install <selected package>

When I try to do this:

sudo apt-get install build-essential ./configure make -j4 # adjust according to your available CPU capacity sudo make install

This is the output after ./configure

$ ./configure/usr/bin/env: ‘python’: No such file or directory

$ python --version The program 'python' can be found in the following packages: * python-minimal * python3Try: sudo apt install <selected package>$which -a python

no output

How can I solve this? I am new to Ubuntu.
