根因分析

该包使用 PEP 517 构建后端，但所需的构建依赖（如 setuptools、wheel 或自定义后端）未安装在隔离的构建环境中。

English

The package uses a PEP 517 build backend but the required build dependency (e.g., setuptools, wheel, or a custom backend) is not installed in the isolated build environment.

解决方案

  1. 90% 成功率 
    pip install setuptools wheel cython  # then pip install package
  2. 85% 成功率 
    pip install setuptools wheel && pip install package --no-build-isolation

无效尝试

常见但无效的做法:

  1. 70% 失败

    Disabling build isolation requires the build backend to already be installed in the current environment; if it isn't, the error persists.

  2. 80% 失败

    Upgrading pip does not install the missing build backend specified in pyproject.toml [build-system].requires.
