Python3.12使用r6sapi报错：module 'asyncio' has no attribute 'coroutine'

问题描述 #

首次使用Asyncio调用r6sapi编写Python脚本时，触发以下错误：

AttributeError: module 'asyncio' has no attribute 'coroutine'. Did you mean: 'coroutines'?

完整报错栈如下：

Traceback (most recent call last):
  File "c:\Users\cincy\OneDrive\Documents\PythonSiegeAPI\r6api.py", line 2, in <module>
    import r6sapi as api

    @asyncio.coroutine  # pragma: no branch
     ^^^^^^^^^^^^^^^^^

使用的代码示例：

import asyncio
import r6sapi as api

async def run():
    auth = api.Auth("email", "password")
    
    player = await auth.get_player("PLAYER_NAME", api.Platforms.UPLAY)
    operator = await player.get_operator("sledge")
    print(operator.kills)

    await auth.close()
    
asyncio.get_event_loop().run_until_complete(run())

解决办法 #

原因分析 #

Python 3.12正式移除了asyncio.coroutine装饰器（这是旧版生成器协程的写法，Python 3.7+已推荐使用async def定义协程），而当前安装的aiohttp版本过于老旧，仍在调用这个已被移除的API，导致报错。

具体修复步骤 #

• 升级aiohttp到兼容Python3.12的版本
  执行以下命令：

  pip uninstall aiohttp
  pip install --upgrade aiohttp
  

  升级后aiohttp会使用新版协程写法，不再依赖asyncio.coroutine。

• 优化代码的协程运行方式
  原代码中asyncio.get_event_loop().run_until_complete(run())是旧版写法，Python3.7+推荐用更简洁的asyncio.run()替代，修改后的代码：

  import asyncio
  import r6sapi as api
  
  async def run():
      auth = api.Auth("email", "password")
      
      player = await auth.get_player("PLAYER_NAME", api.Platforms.UPLAY)
      operator = await player.get_operator("sledge")
      print(operator.kills)
  
      await auth.close()
      
  asyncio.run(run())
  

• 若r6sapi本身不兼容Python3.12
  升级aiohttp后仍报错的话，说明r6sapi库未适配Python3.12，此时需要降级Python版本到3.11及以下，或等待r6sapi发布兼容新版本的更新。
