我正在尝试通过 pip 安装 scipy 包。 在 Windows 10 64 位 simpl Python 2.7.3 上运行，没有 anaconda。 你能告诉我在安装包 scipy 时出了什么问题吗？

非常感谢您的回答

Answer 1

如前所述，尝试使用 .whl

你应该从这里下载正确的文件http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy 然后 cd 到您下载 scipy_some_version.whl 的位置并

    pip install scipy_some_version.whl

Answer 2

您不能只在 Windows 上使用 pip install scipy。使用 Gohlke 轮子或 Anaconda。

Answer 3

由于 Windows 没有任何类似于 Linux 中的包管理器，因此您不能只使用pip install <packagename>，因此最好安装Installing the SciPy Stack 中提到的科学 Python 发行版之一。但是，如果这不是一个选项，Christoph Gohlke 提供了pre-built Windows installers for many Python packages，包括所有核心 SciPy 堆栈，它们运行得非常好。

Answer 4

我遇到了同样的错误，结果发现 scipy 对 numpy 不满意。 然后我使用了“conda intsall scipy”，它安装了所需的版本，没有任何错误。

强烈建议使用 Windows anaconda 安装的任何人。如果需要任何旧版本的python，则可以创建虚拟环境并安装所需版本的python。
