在Mac OSX上安装Pandas

Question

我在Mac OSX计算机上安装Python Pandas库时遇到问题.

我在终端输入以下内容:

$ sudo easy_install pandas

但后来我得到以下内容:

我确实安装了Xcode和gcc,但只有当我键入时才会找到gcc:

$ gcc
-bash: gcc: command not found

$ gcc-4.2
i686-apple-darwin11-gcc-4.2.1: no input files

我该怎么办？

Answer 1

安装pip.

然后安装pandas有pip:

pip install pandas

Answer 2

你可以用自制软件安装python:

brew install python

确保OSX使用正确的路径:

which python

然后你可以使用pip工具来安装pandas:

pip install pandas

确保已安装所有依赖项.我遵循了这个教程:http://penandpants.com/2013/04/04/install-scientific-python-on-mac-os-x/

在我的机器上正常工作.

Answer 3

您需要安装XCode并且您需要确保为XCode 安装命令行工具,以便获得gcc.

Answer 4

尝试

pip3 install pandas 

从终端。也许你原来的 pip install pandas 引用了 anaconda 发行版

Answer 5

我建议使用 macport 或 fink 来安装 pandas：

1. 从 App Store 安装 XCode，这将安装 3 个编译器：clang、gcc（“apple”）和 gcc（“normal”）
2. 安装 macports (www.macports.org) 或 fink (www.finkproject.org)
3. 永远不要再使用你的 mac python，并通过 fink/macport 安装所有 python 模块，并享受它为你处理依赖项的乐趣。

在 macports 中安装 pandas 非常简单： sudo port install py27-pandas

你通常在 /opt/local 中安装 macport，在 /sw 中安装 fink，我建议（尽管这可能是个坏建议）你将你的 fink/mac ports python 符号链接到你的系统 python，如下所示： /usr/bin/python -> /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7
