带有 Python 2.7 安装问题的 Windows 上的 SciPy

Question

想知道是否有人遇到过类似的问题并已经有了解决方案？使用 Windows 7。

    Note: if you need reliable uninstall behavior, then install
    with pip instead of using `setup.py install`:

      - `pip install .`       (from a git repo or downloaded source
                               release)
      - `pip install scipy`   (last SciPy release on PyPI)

Answer 1

某些包，例如 Scipy，需要使用 pip 构建编译器。 Windows 不附带编译器，因此您需要下载 Windows 可以使用的 scipy 二进制文件。

来自加州大学欧文分校的一位名叫 Christopher Gohlke 的出色人士开发了这些 Windows 二进制文件。你可以找到他们here。

注意：如果您没有安装 Numpy，则无法安装 SciPy。您还需要下载 Numpy 二进制文件（也可以找到 here）。只需按照以下步骤下载 numpy 模块，就像下载 scipy 模块一样。

您安装哪个链接取决于您是 64 位还是 32 位版本的 python，如果您已将它安装到 PATH，您可以通过在命令行上使用 python 命令来检查它。这是它的可视化：

C:\Users\Bobby>python
Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec  5 2015, 20:40:30) [MSC v.1500 64 bit (AMD64)] on win32

您可以在括号中找到您的版本。如您所见，我正在运行 64 位版本的 python。所以我会下载“scipy-0.18.0-cp27-cp27m-win_amd64.whl”文件，它假设我在 64 位版本的 python（由 amd64 表示）上运行 python 2.7（由 cp27 表示）。

注意：还要确保 pip 已更新。您可以使用以下命令对其进行更新：

C:\Users\Bobby\Downloads>pip install --upgrade pip

下载 SciPy 二进制文件后，将工作目录更改为下载文件夹并运行 pip，但在下载中使用 .whl 文件。这是它的可视化：

C:\Users\Bobby>cd Downloads
C:\Users\Bobby\Downloads>pip install scipy-0.18.0-cp27-cp27m-win_amd64.whl
Processing c:\users\bobby\downloads\scipy-0.18.0-cp27-cp27m-win_amd64.whl
