ESP home command line installation issues - hassbian

I’m having a nightmare trying to install esphome. Current issues are below:

**pi@hassbian** : **~ $** pip install esphome

-bash: pip: command not found

**pi@hassbian** : **~ $** pip3 install esphome

Traceback (most recent call last):

File "/usr/bin/pip3", line 9, in <module>

from pip import main

ImportError: cannot import name 'main'
