python - 在 Windows 上安装 scipy 时出错

Question

我正在使用 windows 机器和 2.7 版本的 python。我已经安装了 numpy，现在我正在尝试安装 scipy。我已经尝试使用 easy install 命令并通过下载 zip 文件然后运行 ​​setup.py 文件来安装它。

当我尝试通过 easy_install 安装它时

我是 python 的新手，我不明白为什么会收到这些错误。我在 Python27 的 Lib 文件夹中没有看到文件夹，正如预期的那样，当我在终端上输入 import scipy 时，我收到了 ImportError: No module named scipy 错误。

Answer 1

您似乎没有安装编译器来编译 scipy 及其依赖项。这是 Windows 上的常见问题。您需要安装一个编译器(漫长的路线)或下载适用于 Windows 的预编译二进制文件(对于您需要在 Windows 上使用的软件包，通常更加用户友好)。

Individual binary and source packages (from scipy.org/install.html)

The maintainers of many of the packages in the SciPy stack provide “official” binary installers for common Windows and OS-X systems that can be used to install the packages one by one. These installers are generally built to be compatible with the Python binaries available from python.org.

我会尝试从 http://sourceforge.net/projects/scipy/files/scipy/ 的 sourceforge 获取最新版本
