Root Cause

uvloop wheel is missing for the current Python version or platform, or a stale uvloop build is being imported.

generic

中文

当前 Python 版本或平台缺少 uvloop wheel，或正在导入陈旧的 uvloop 构建。

Workarounds

  1. 95% success 
    uvicorn app:app --loop asyncio
  2. 85% success 
    python -c 'import sys; print(sys.version)'
pip install --only-binary=:all: 'uvloop>=0.19'

Dead Ends

Common approaches that don't work:

  1. 60% fail

    May install a wheel built for a different Python ABI; import still fails.

  2. 70% fail

    Auto still prefers uvloop on Linux when installed; the import error persists.
