根因分析

未安装 Python 开发头文件（Python.h），因此 setuptools 在构建步骤中无法编译 C 扩展。

English

The Python development headers (Python.h) are not installed, so setuptools cannot compile a C extension during the build step.

解决方案

  1. 97% 成功率 
    On Debian/Ubuntu: sudo apt-get install python3-dev; on RHEL: sudo dnf install python3-devel; then retry pip install.
  2. 90% 成功率 
    Run pip install --only-binary=:all: mypkg to force wheel usage.

无效尝试

常见但无效的做法:

  1. 92% 失败

    The failure is a missing system header, not an outdated setuptools.

  2. 90% 失败

    Does not provide Python.h.

  3. 85% 失败

    The header does not exist at that path without installing python3-dev.
