Please help me on this

You need Python 2.x.

Using 3.x is not supported.

[hemanthaSN]

Thank you so much. It worked using python 2.x.

[parmentelat]

you guys do realise that python2 will be end-fo-lived in less than a year now, after having been kept on artificial respiration for 5 years, right ?
don't you think it would be better to rely on python3 now ?

[parmentelat]

I realise this might be a long shot, but if that's an option, I'd suggest you at the very least use some band-aid to get this to work on both flavours:

$ python2 -c 'from future import print_function; import sys; print(sys.version_info[:3])'
(2, 7, 15)
$ python3 -c 'from future import print_function; import sys; print(sys.version_info[:3])'
(3, 7, 2)

@parmentelat There is ongoing effort to make this happen, see nodejs/node#25789. PRs are always welcomed.

Closing this as the problem was resolved.
