根因分析

PEP 517 构建后端子进程失败，因为 pyproject.toml 中声明的构建时依赖（例如 Cython）未安装在隔离的构建环境中。

English

A PEP 517 build backend subprocess failed because a build-time dependency (e.g., Cython) is declared in pyproject.toml but not installed in the isolated build environment.

解决方案

  1. 88% 成功率 
    python -m pip install Cython numpy
python -m pip install --no-build-isolation the-package
  2. 85% 成功率 
    python -m pip install --only-binary=:all: --extra-index-url https://download.pytorch.org/whl/cpu the-package

无效尝试

常见但无效的做法:

  1. 70% 失败

    The isolated build env does not inherit the outer env, so Cython is still missing inside it.

  2. 65% 失败

    Without isolation, the build runs in the current env, which still lacks Cython.

  3. 90% 失败

    The package source is not yours to edit; pip re-downloads the pristine sdist.
