SQLCipher import with Python 2.7 - ImportError setuptools - Ubuntu

SQLCipher
1

From python 2.7, I’m developing a program which requires the encryption of a database. In this way, I wish to install on my PC, with Ubuntu, the fork of pysqlite I mean pysqlcipher. I’m following this tutorial and then I have followed all the following steps:

$ git clone https://github.com/leapcode/pysqlcipher/
$ cd pysqlcipher
$ python setup.py build_sqlcipher  # Build against the system libsqlcipher

But with the last line, my terminal raises the following error message:

Traceback (most recent call last):
  File "setup.py", line 38, in <module>
    import setuptools
ImportError: No module named setuptools

Thank you for your help!
