Bolt library is not installing

I’m not using bolt library in python. it will show this type of error.

check you’re python version…you’re error says you are using python version below 3.5. Upgrade you’re python verson and then install boltiot library…and proceed. If possible share the code you wrote.

I wrote this code
Using ‘pip install --upgrade pip updates’ the pip for python 2.
Try using ‘sudo -H pip3 install --upgrade pip’ instead for python 3

After that i wrote this code but not installing library
