Root Cause

Using asyncio.run() in Python 3.6 or earlier, where it was introduced in Python 3.7.

generic

中文

在 Python 3.6 或更早版本中使用 asyncio.run()，该函数在 Python 3.7 中引入。

Workarounds

  1. 85% success Use asyncio.get_event_loop().run_until_complete() on a new loop 
    loop = asyncio.new_event_loop()
asyncio.set_event_loop(loop)
loop.run_until_complete(main())
  2. 95% success Upgrade Python to 3.7+ 
    python3 --version  # ensure >= 3.7

Dead Ends

Common approaches that don't work:

  1. Using asyncio.get_event_loop().run_until_complete() without checking loop status 60% fail

    If the loop is already running, this may cause 'Event loop is already running' error.

  2. Upgrading Python but not updating code 30% fail

    The error is version-specific; upgrading Python resolves it but code may need adjustments.
