python - 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

这适用于预装在 Mac 上的 2.7，但是在使用时

sudo pip3 install -U nltk

尝试在 3.4 下安装我得到以下错误:

    /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)

  warnings.warn(msg)

error: invalid command 'bdist_egg'

Traceback (most recent call last):

    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 goggling 看到了这个问题的提示，但没有确定的答案。

Answer 1

我刚刚从 PyPI 下载了 3.0.0b2 .tar.gz 文件, 解压缩，然后运行 ​​

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。我还应该注意我使用 MacPorts对于 Python 和所有其他语言，但希望这不会产生影响。
