Ipython : Installation error, unable to find _sqlite.so

On trying to install ipython for Python3.4 I get a message that it is already installed.

pip3 install ipython
Requirement already satisfied (use --upgrade to upgrade): ipython in /usr/local/lib/python3.4/site-packages

But when I try to run it with ipython3 notebook I get all this:

Traceback (most recent call last):

ImportError: No module named '_sqlite3'

Assuming that the last line is the most important

ImportError: No module named '_sqlite3'

I tried to install all sorts of dependencies for it:

apt-get install sqlite3 libsqlite3-dev

When I tried installing Pysqlite via pip3 install pysqlite :

Collecting pysqlite
  Using cached pysqlite-2.6.3.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 20, in <module>
      File "/tmp/pip-build-ggtq7_wu/pysqlite/setup.py", line 85
        print "Is sphinx installed? If not, try 'sudo easy_install sphinx'."
                                                                       ^
    SyntaxError: Missing parentheses in call to 'print'

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-ggtq7_wu/pysqlite

However Sphinx is already installed. I even reinstalled it.

pip3 install sphinx
Requirement already satisfied (use --upgrade to upgrade): sphinx in /usr/local/lib/python3.4/site-packages

Requirement already satisfied (use --upgrade to upgrade): pytz>=0a in /usr/local/lib/python3.4/site-packages (from babel>=1.3->sphinx)

Hence I have not been able to resolve it because evidently that file _sqlite3.so which should be in /usr/local/lib/python3.4/lib-dynload does not exist and I cannot find a way to install it.
