Root Cause

uvloop is not installed in the active environment, or it is installed for a different Python interpreter than the one running the app (common with venvs and multi-version setups).

generic

中文

当前环境中未安装 uvloop，或它安装在运行应用所用解释器之外的其他 Python 中（在 venv 与多版本环境中常见）。

Workarounds

  1. 92% success 
    python -c 'import sys; print(sys.executable)'
python -m pip install uvloop
python -c 'import uvloop; print(uvloop.__version__)'
  2. 90% success 
    try:
    import uvloop
    uvloop.install()
except ImportError:
    pass  # use default asyncio loop

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Installs into the system Python, not the venv, so the app still cannot import it.

  2. 85% fail

    Mixes incompatible ABI builds and typically produces ImportError on the C extension.
