Error installing Z2Pack 2.1.1

[Rajdeep Banerjee]

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

Downloading/unpacking fsc.export (from z2pack==2.1.1)
  Downloading fsc.export-1.1.0.tar.gz
  Running setup.py (path:/tmp/pip_build_rajdeep/fsc.export/setup.py)
egg_info for package fsc.export
    error in fsc.export setup command: Invalid environment marker:
python_version < "3"
    Complete output from command python setup.py egg_info:
    error in fsc.export setup command: Invalid environment marker:
python_version < "3"

----------------------------------------
Cleaning up...
Command python setup.py egg_info failed with error code 1 in
/tmp/pip_build_rajdeep/fsc.export
Storing debug log for failure in /tmp/tmp3bth1l3g


I thought it is due to python version but I have python 3.5 as shown below:


[rajdeep at anna: Z2Pack-master-2.1.x]:python
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!
