Conda 骨架 pypi 因 pmdarima 失败——AttributeError numpy disutils

Question

我正在尝试在 conda env 中安装 pmdarima 包，因为它需要 statsmodels

conda skeleton pypi pmdarima

这与下面描述的 numpy disutils 相关的相同 AttributeError 失败。

类似于这个问题的提问者：Conda skeleton pypi: ModuleNotFoundError: No module named 'numpy' 我也无法让它工作。

conda install -n _build numpy

然后我尝试了上面链接的 SO 问题中提出的建议并运行：

conda skeleton pypi --extra-specs numpy pmdarima

这会导致输出很长，但据我所知，关键是：

有什么想法吗？非常感谢您，非常感谢！

Answer 1

不确定基于 NumPy 的构建的正确分辨率是什么，但 the setup.py does check for an sdist argument，它分支使用 setuptools 构建而不是 numpy。因此，以下似乎避免了导致问题的代码：

conda skeleton pypi --setup-options sdist pmdarima

我怀疑这种解决方法的缺点是没有完成 Cython 编译，但并不完全确定。

您可能想file an issue on the pmdarima GitHub 看看是否有任何开发者有想法。否则，在您想要的环境中pip install 包可能更有效（只要该环境不是base）。

@merv 谢谢你的帮助！有趣的是，这适用于骨架，但在运行 conda-build 时失败，输出如下（截断直到出现错误）：

我承认此时我们已经超出了我的想象，（我需要以某种方式编辑 meta.yaml 文件吗？这很疯狂吗？）但会尝试按照您的建议打开一个问题，再次非常感谢它。
