Dear sir,

I tried following your suggestion and found the following:
>> sudo pip install -U setuptools
Requirement already up-to-date: setuptools in /usr/local/lib/python2.7/dist-packages
Cleaning up...

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.
>> sudo python -m pip install --user /home/rajdeep/soft/Z2Pack-master-2.1.x

...

Downloading/unpacking fsc.export (from z2pack==2.1.1)

    Complete output from command python setup.py egg_info:
    error in fsc.export setup command: Invalid environment marker: python_version < "3"

Please help. Thanks in advance.

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I think this issue might be due to an outdated version of the 'setuptools' package which does not recognize these environment markers.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:

Command python setup.py egg_info failed with error code 1 in /tmp/pip_build_rajdeep/fsc.export

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

[rajdeep@anna: Z2Pack-master-2.1.x]:python
Python 3.5.3 (default, Apr 22 2017, 00:00:00)
[GCC 4.8.4] on linux

Please help. Thanks in advance!
