在Mac OS 10.9上安装适用于Python 3.4的nltk

Question

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

sudo pip install -U nltk

这适用于Mac上预装的2.7，但在使用时

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'

ImportError



During handling of the above exception, another exception occurred:

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

OSError: Could not build the egg.

Python 3.4使用brew安装，并且正确安装了bumpy和setuptools。 我通过一些令人难以置信的但没有明确的答案看到了这个问题的暗示。

Answer 1

我刚从PyPI下载了3.0.0b2 .tar.gz文件，解压缩并运行

sudo python3 setup.py install

在解压缩的目录中，一切正常。 我尝试从pip3安装时遇到了同样的问题。 我还应该注意到我使用MacPorts进行Python以及其他所有操作，但希望这不会产生任何影响。
