Root Cause

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.

generic

中文

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。

Workarounds

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

Dead Ends

Common approaches that don't work:

  1. 70% fail

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

  2. 90% fail

    pip cannot conjure a package the index does not serve.
