Conda骨架pypi失败，并显示pmdarima -- AttributeError numpy disutils

Question

我正在尝试在conda环境中安装pmdarima包，因为它需要statsmodel <0.12，我还想使用statmodel的最新版本来完成这个项目。我的理解是有限的，但我首先尝试了

conda skeleton pypi pmdarima

这失败了，与下面描述的numpy disutils相关的AttributeError是相同的。

类似于这个问题中的提问者：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问题中列出的建议，并运行：

conda skeleton pypi --extra-specs numpy pmdarima

这导致了相当长的输出，但据我所知，关键部分是：

有什么想法吗？非常感谢您提前这么多，非常感谢！

Answer 1

不确定基于NumPy的构建的正确解决方案是什么，但是the setup.py does check for an sdist argument，哪个分支使用setuptools而不是numpy进行构建。因此，以下代码似乎可以避免导致问题的代码：

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，但不能完全确定。

你可能想用file an issue on the pmdarima GitHub看看有没有开发人员有想法。否则，在您想要的环境中使用pip install包可能会更有效(只要该环境不是基于的)。

@merv感谢您的帮助！有趣的是，这对框架有效，但在运行conda-build时失败，输出如下(截断到出现错误)：

我承认我们在这一点上很难理解，(我需要以某种方式编辑meta.yaml文件吗？这是不是很疯狂？)但我会试着按你的建议开一期，再一次感谢。
