Getting an error with async / await

[arotabi]

Hi,

I'm a total rookie with the Telegram API so was planning on going through the Intro to the API sample codes.
I'm falling at the first hurdle so some help would be appreciated.

When I run the sample code:

import asyncio
import telegram

async def main():
bot = telegram.Bot("TOKEN") # with my valid token
async with bot:
print(await bot.get_me())

if name == 'main':
asyncio.run(main())

I get the following error:

(Test1) D:\Projects\Python\Alert>python test2.py
Traceback (most recent call last):
File "test2.py", line 15, in
asyncio.run(main())
File "C:\Users\arota.conda\envs\Test1\lib\asyncio\runners.py", line 44, in run
return loop.run_until_complete(main)
File "C:\Users\arota.conda\envs\Test1\lib\asyncio\base_events.py", line 616, in run_until_complete
return future.result()
File "test2.py", line 10, in main
async with bot:
AttributeError: aexit

Could someone help me with where I'm going wrong.
Cheers.

You didn't install the pre version of our library, which you can do with pip install -U python-telegram-bot --pre.
