Dear sir, as you suggested I installed python3 setuptools and the z2pack got installed with the pip command. The last few lines are as follows:
...
Could not find .egg-info directory in install record for z2pack==2.1.1 from file:///home/rajdeep/soft/Z2Pack-master-2.1.x
Successfully installed numpy scipy decorator blessings sortedcontainers msgpack-python fsc.locker fsc.export fsc.formatting fsc.iohelper z2pack Cleaning up...
Is the warning about "egg-info directory" anything serious to care about or I can just ignore it? Thank you very much for your help.
best regards, Rajdeep

Dear Rajdeep,
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.
So in this case, you can try: sudo python3 -m pip install -U setuptools python3 -m pip install --user PATH_TO_Z2PACK
Best regards,
Dominik

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.

Hi Rajdeep,
I think this issue might be due to an outdated version of the 'setuptools' package which does not recognize these environment markers.
Can you try running
'pip install -U setuptools'
before installing Z2Pack?
Best regards, Dominik

Hi, I am trying to install Z2Pack 2.1.1 (from source file). I am getting the following error:

I thought it is due to python version but I have python 3.5 as shown below:
Python 3.5.3 (default, Apr 22 2017, 00:00:00) [GCC 4.8.4] on linux Type "help", "copyright", "credits" or "license" for more information.
Please help. Thanks in advance!
