根因分析

该软件包需要一个 Cython 扩展文件（.pxd），但该文件在源代码分发包中缺失，通常是因为生成该文件的构建脚本在打包前未运行。

English

The package requires a Cython extension file (.pxd) that is missing from the source distribution, often because it is generated by a build script that was not run before packaging.

解决方案

  1. 从版本控制系统（如 git）安装该软件包，其中包含生成 .pxd 文件的构建脚本：pip install git+https://github.com/user/package.git
  2. 修补源代码分发包：下载 .tar.gz，解压，运行构建脚本（如 python setup.py build_ext --inplace）生成缺失的 .pxd，然后重新打包并用 pip install ./package-version.tar.gz 安装。
  3. 联系软件包维护者，请求发布包含缺失 .pxd 文件的固定源代码分发包或 wheel。

无效尝试

常见但无效的做法:

  1. Manually creating a dummy .pxd file with the same name in the package directory 95% 失败

    The .pxd file has specific type declarations and interfaces that must match the .pyx file; a dummy file will cause compilation errors or silent failures.

  2. Running pip install --no-build-isolation to use system Cython 90% 失败

    The missing .pxd is not a Cython version issue; it's a missing source file that no Cython version can generate without the original build script.

  3. Installing the package from a pre-built wheel instead of source 70% 失败

    If the package maintainer did not publish a wheel for the platform/Python version, this option is not available.
