Although I install python-telegram-bot, error of no module named 'telegram'

Question

I installed telegram packages. But when I try to run the simple example, echobot.py, I got an error:

Traceback (most recent call last):
    File "echobot.py", line 8, in <module>
import telegram ImportError: No module named 'telegram'

Can anyone help me?

I install using git:

$ git clone https://github.com/python-telegram-bot/python-telegram-bot

after this:

$ python -i

import telegram

Answer 1

You are not installing it. You are just downloading it.
Run these:

cd python-telegram-bot
python setup.py install

(stated in readme of the GitHub page)

Alternatively, you can use pip. It's easier to use.

pip install python-telegram-bot
