Root Cause

A package using PEP 517 build system failed to produce a wheel, typically due to missing C compiler, headers, or build dependencies.

generic

中文

使用 PEP 517 构建系统的包无法生成 wheel，通常是因为缺少 C 编译器、头文件或构建依赖。

Workarounds

  1. 90% success 
    On Debian/Ubuntu: `sudo apt-get install build-essential python3-dev`. On macOS: `xcode-select --install`. Then retry `pip install foo`.
  2. 80% success 
    `pip install --only-binary=:all: foo` or fetch a manylinux wheel from PyPI/conda-forge.

Dead Ends

Common approaches that don't work:

  1. 85% fail

    Upgrading pip does not provide the missing system toolchain.

  2. 70% fail

    Disabling build isolation can help only if build deps are preinstalled; usually they are not.
