How I can solve it,Think you!!

Answer 1

It looks like your default Python is 3.x, but the Node build scripts require Python 2.x.

According to these instructions you can fix it by setting the PYTHON environment variable to point to your Python 2 executable:

export PYTHON=`which python2`

Answer 2

It's because your default python is python3.x . Node.js recommend python2.6 / python2.7 to compile the source.
Try to check your python command via:

ls -l /usr/bin/python

it will show lrwxrwxrwx 1 root root 9 Apr 3 15:46 /usr/bin/python -> python3

To make python2.7 as the default python command use:

sudo ln -sf `which python2.7` `which python`
ls -l /usr/bin/python

now it should be lrwxrwxrwx 1 root root 9 Apr 3 15:46 /usr/bin/python -> python2.7
