根因分析

一个带 C 扩展（Cython）的包正从 sdist 构建，但编译器工具链或 Python 开发头文件缺失/不兼容，导致 gcc 在扩展构建期间失败。

English

A package with C extensions (Cython) is being built from sdist but the compiler toolchain or Python development headers are missing/incompatible, so gcc fails during the extension build.

generic

解决方案

  1. 90% 成功率 
    Install a prebuilt wheel: pip install --only-binary=:all: foo  # avoids compilation entirely
  2. 82% 成功率 
    Install the toolchain: sudo apt install build-essential python3-dev  # then pip install foo

无效尝试

常见但无效的做法:

  1. 65% 失败

    Disabling isolation doesn't install gcc or python-dev headers; the compiler is still absent.

  2. 60% 失败

    Build tooling versions don't affect the missing system compiler/headers; compilation still fails.
