根因分析

包的 pyproject.toml 声明了构建后端（如 hatchling），但配置的索引（通常是私有镜像）中不存在该后端。

English

The package's pyproject.toml declares a build backend (e.g., hatchling) that is not available on the configured index, often because a private mirror lacks it.

解决方案

  1. 90% 成功率 
    Add PyPI as a secondary index: `pip install --extra-index-url https://pypi.org/simple <pkg>`.
  2. 88% 成功率 
    Pre-install the build backend and disable isolation: `pip install hatchling && pip install --no-build-isolation <pkg>`.

无效尝试

常见但无效的做法:

  1. 70% 失败

    Uses the current env's build backend; if hatchling is not installed there either, the same error appears.

  2. 90% 失败

    pip cannot conjure a package the index does not serve.
