python:pandas安装错误

Question

我有 MacOS 10.6.x 的 EPD 7.1 学术发行版，其中有 pandas 0.3 版本。最新的官方版本是0.5.0，所以我想我会升级到最新的。

这是我所做的:

1. 保存了来自 here 的源代码 zip 文件
2. 执行sudo python setup.py install
3. 通过执行nosetests pandas来运行测试

请记住，我是Python的新手。任何有关我的安装失败原因的见解将不胜感激。以下是错误的片段。整个日志可以在 Error log 找到

结果:

在 55.011 秒内运行 1498 次测试失败(跳过=4，错误=91，失败=14)

======================================================================
ERROR: test_generate (test_daterange.TestGeneration)

    rng2 = list(generate_range(START, END, timeRule='WEEKDAY'))
TypeError: generate_range() got an unexpected keyword argument 'timeRule'

@wesm - 感谢您的快速回复。下次我一定会使用邮件列表。所以我实际上回溯...安装了官方 0.5.0 版本并从源代码编译。我收到 3 个错误(见下文)。我在运行 sudo python setup.py install

时没有遇到任何问题

提出这个问题的最佳地点是 mailing list (幸运的是，谷歌快讯让我立即知道了这一点!)。您的安装似乎失败，并且仍在使用 pandas 0.3.0。您运行python setup.py install时是否出现任何错误？如果您是从 git 快照构建的，则可能需要升级 Cython 安装 (sudo easy_install -U Cython)。如果这不起作用，请尝试取消现有的 pandas 安装:

sudo rm -rf/Library/Frameworks/EPD64.framework/Versions/7.1/lib/python2.7/site-packages/pandas

并重新安装。压缩包位于 PyPI包括预构建的 Cython 源。如果你无论如何都从源代码构建，我建议无论如何从 git 上的 head 修订版构建。距离发布 pandas 0.6.0 还有几天。
