Root Cause

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.

generic

中文

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。

Workarounds

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

Dead Ends

Common approaches that don't work:

  1. 70% fail

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

  2. 80% fail

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