Root Cause

Build backend requires tools (e.g., Cython, numpy) not declared in build-system.requires, and build isolation hides them.

generic

中文

构建后端需要未在 build-system.requires 中声明的工具（如 Cython、numpy），而构建隔离隐藏了它们。

Workarounds

  1. 85% success 
    pip install -U pip setuptools wheel cython numpy
pip install foo
  2. 80% success 
    pip install --only-binary=:all: foo

Dead Ends

Common approaches that don't work:

  1. 55% fail

    Requires all build tools pre-installed globally; often fails with missing headers or wrong versions.

  2. 90% fail

    Transient network issues aside, missing build deps won't resolve by retrying.
