create_task = asyncio.async: SyntaxError: invalid syntax

问题

I\'m creating a bot for Discord, and I just wrote this simple code:

import discord

TOKEN = \"token\"

client = discord.Client()


@client.event
async def on_ready():
    print(\'Bot is ready.\')


client.run(TOKEN)

and it produces the following error:

Traceback (most recent call last):

SyntaxError: invalid syntax

I searched and searched in the internet, and most of the people say to use Python 3.7, and that\'s what I\'ve been using. Also, I\'ve been using PyCharm as my IDE for Python.

回答1:

Where does the error come from?

The version of discord.py you are using does not support Python 3.7 (in which async becomes a reserved keyword), as explained in this issue. This version of discord.py, which is the default branch on the GitHub repo, is sadly the one installed by Pip.

How to fix it

You can either:

• downgrade your version of Python to 3.6.
• install another version of discord.py, based on the rewrite branch which is under active development, for example with the command : python3 -m pip install --user -U https://github.com/Rapptz/discord.py/archive/rewrite.zip

回答2:

You can manually edit the file and change that line from create_task = asyncio.async to create_task = getattr(asyncio, 'async')
