标签： python numpy pandas

我在Windows 8中使用python 2.7.8，在cmd上我编写了easy_install pandas。经过一些处理后，它给了我一个错误，并让我下载vcpython27。

on cmd：

完全不可理解。有没有解决这个问题的想法？

1 个答案:

答案 0 :(得分：4)

pandas（以及其他各种python库）使用C语言来执行一些繁重的工作。 Pip包通常在客户端下载和编译C源代码，而在* nix机器上这很好，因为它们通常有一个编译器。但是，Windows并没有附带编译器默认值。所以你的选择是（从最难到最简单）：

  1. 安装C编译器（如果你不做任何C则很烦人）
  2. 安装一个类似anaconda或者enthought的python发行版，为你处理这些事情（这些很好很容易，但你可能已经有了一个你想要保留的自定义环境。）
  3. 使用 wheel 安装软件包 - 这些是鸡蛋的后继产品，不需要在窗口上进行编译。有些包装已装有轮子，但不是全部。但是，在http://www.lfd.uci.edu/~gohlke/pythonlibs/处有非正式的车轮收集。您可以下载车轮，并使用pip进行安装。
    4. 编辑：正如@cel - 所建议的那样，为了上帝的缘故，不要使用easy_install！使用pip代替 - 许多套餐你需要已经有pip会找到的轮组件。如果你还没有pip，那么试试easy_install pip（就像使用Internet Explorer的唯一原因是使用它来下载另一个浏览器;）
