在 Mac OS 10.9 上为 Python 3.4 安装 nltk

Question

我一直试图让 nltk 在 python 3.4 下运行但没有成功。使用http://www.nltk.org/install.html 处的说明：

sudo pip install -U nltk

这适用于 Mac 上预装的 2.7，但是在使用时

sudo pip3 install -U nltk

尝试在 3.4 下安装，我收到以下错误：

    /usr/local/Cellar/python3/3.4.1_1/Frameworks/Python.framework/Versions/3.4/lib/python3.4/distutils/dist.py:260: UserWarning: Unknown distribution option: 'zip_safe'

  warnings.warn(msg)

    raise ImportError

ImportError



During handling of the above exception, another exception occurred:



Traceback (most recent call last):

    raise IOError('Could not build the egg.')

OSError: Could not build the egg.

Python 3.4 是用 brew 安装的，bumpy 和 setuptools 都安装正确。我通过一些观察看到了这个问题的提示，但没有明确的答案。

Answer 1

我刚刚从PyPI 下载了3.0.0b2 .tar.gz 文件，解压后运行

sudo python3 setup.py install

在解压缩的目录中，一切正常。我在尝试从pip3 安装时遇到了同样的问题。我还应该注意，我将MacPorts 用于 Python 和其他所有内容，但希望这不会产生影响。
