Root Cause

The package uses PEP 517 and pip must build a wheel, but the wheel build fails — typically due to missing C toolchain, missing headers (e.g., libssl-dev), or a compiler error in the C extension.

包使用 PEP 517，pip 必须构建 wheel，但 wheel 构建失败——通常由于缺少 C 工具链、缺少头文件（如 libssl-dev），或 C 扩展中的编译器错误。

Workarounds

  1. 80% success 
    # Debian/Ubuntu
sudo apt-get install -y build-essential python3-dev libssl-dev libffi-dev
# macOS
brew install openssl@3
pip install <package>
  2. 75% success 
    pip install --only-binary=:all: <package>
# fallback: download from https://pypi.org/project/<package>/#files

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Cache is not the issue; the compile step fails every time.

  2. 80% fail

    Pre-releases rarely ship wheels for every platform; the compile still fails.
