Root Cause

With build isolation, pip creates a temp env and installs build deps from pyproject.toml. If [build-system] is missing or requires only 'wheel', setuptools isn't present and the build fails.

generic

中文

在构建隔离下，pip 创建临时环境并从 pyproject.toml 安装构建依赖。如果缺少 [build-system]，或只声明 'wheel'，则没有 setuptools，构建失败。

Workarounds

  1. 92% success 
    # pyproject.toml
[build-system]
requires = ["setuptools>=64", "wheel"]
build-backend = "setuptools.build_meta"
  2. 85% success 
    pip install --upgrade setuptools wheel
pip install . --no-build-isolation

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Build isolation ignores the outer env.

  2. 80% fail

    Doesn't populate the isolated build env.

  3. 70% fail

    Removes PEP 518 config; pip falls back to legacy but may still fail.
