create_task = asyncio.async：SyntaxError：语法无效

Question

我正在为Discord创建一个机器人，我只是编写了以下简单代码：

import discord

TOKEN = "token"

client = discord.Client()


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


client.run(TOKEN)

并产生以下错误：

Traceback (most recent call last):
  File "/Users/pcaires/Desktop/Programação/Python/Discord Bots/Main.py", line 1, in <module>
    import discord
  File "/Users/pcaires/Desktop/Programação/Python/Discord Bots/venv/lib/python3.7/site-packages/discord/__init__.py", line 20, in <module>
    from .client import Client, AppInfo, ChannelPermissions

    create_task = asyncio.async
                              ^
SyntaxError: invalid syntax

我在互联网上进行了搜索，大多数人都说使用Python 3.7，这就是我一直在使用的语言。另外，我一直在使用PyCharm作为我的Python IDE。

Answer 1

错误来自哪里？

您使用的discord.py版本不支持Python 3.7 （其中async成为保留关键字），如this issue中所述。 此版本的discord.py是GitHub repo上的默认分支，可悲的是Pip安装的版本。

如何修复

您可以：

• 将您的Python版本降级为3.6。
• 基于rewrite branch 正在开发中的另一个版本的discord.py ，例如，使用命令：python3 -m pip install --user -U https://github.com/Rapptz/discord.py/archive/rewrite.zip

Answer 2

您可以手动编辑文件并将该行从create_task = asyncio.async更改为create_task = getattr(asyncio, 'async')

Answer 3

不要不要在您的需求中添加 asyncio，它已经在 Python 中（自 3.5 起）。

It is only relevant for Python 3.3, which does not include asyncio in its stdlib.
