Tried to install cchardet python module but fails with a wierd error w.r.t setuptools module

See above for output. note: This is an issue with the package mentioned above, not pip. 

When checked for the presence of 'py31compat.py' in setuptools install directory found 'py34compat.py' instead. Any suggestions on how to overcome this issue

You seem to be using setuptools >= 50 which dropped Python 2.7 support, along with all Python releases under 3.5.

setuptools-svn used to be directly dependent on setuptools.py31compat which has been removed from setuptools in v50. Fortunately, they dropped that import it in 1.3.0.

So you can fix your issue by doing one of the following:

• Downgrade setuptools to <50
• Upgrade setuptools-svn to 1.3.0
