<p>Dear Rajdeep,</p>
<p>It seems that the update of setuptools happened with python 2
instead of 3. You can force pip to use a specific Python
interpreter by calling it as 'python -m pip' instead of simply
calling 'pip', where 'python' should be the specific interpreter
that you want to install something on.</p>
<p>So in this case, you can try:</p>
<tt>sudo python3 -m pip install -U setuptools</tt><br>
<tt>python3 -m pip install --user PATH_TO_Z2PACK</tt>
<p>Best regards,</p>
<p>Dominik<br>

I tried following your suggestion and found the
following:<br>

Requirement already up-to-date: setuptools in

It seems although I have installed python-3.5, but my default is
python-2.7. I changed the alias in bash so that calling python
will call python-3.5. But the problem persists.<br>
