python - Conda 骨架 pypi 因 pmdarima 而失败——AttributeError numpy disutils

Question

我正在尝试在 conda env 中安装 pmdarima 包，因为它需要 statsmodels <0.12，我还想为这个项目使用 statmodels 最新版本。我的理解有限，但我首先尝试了

conda 骨架 pypi pmdarima

这失败了，出现了与下面描述的 numpy disutils 相关的相同 AttributeError。

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 问题中提出的建议并运行:

conda 骨架 pypi --extra-specs numpy pmdarima

这会产生很长的输出，但据我所知，关键部分是:

有什么想法吗？提前致谢，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，以下似乎避免了导致问题的代码:

conda skeleton pypi --setup-options sdist pmdarima

我怀疑此变通办法的缺点是没有完成 Cython 编译，但不完全确定。

您可能想要 file an issue on the pmdarima GitHub看看是否有任何开发人员有想法。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)。
