无法在Mac OS El Capitan上安装nltk

Question

我sudo pip install -U nltk按照nltk文档的建议做了.但是,我得到以下输出:

Collecting nltk
  Downloading nltk-3.0.5.tar.gz (1.0MB)
    100% |????????????????????????????????| 1.0MB 516kB/s 
Collecting six>=1.9.0 (from nltk)
  Downloading six-1.9.0-py2.py3-none-any.whl
Installing collected packages: six, nltk
  Found existing installation: six 1.4.1
    DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
    Uninstalling six-1.4.1:
Exception:

基本上,它无法从1.4.1升级到1.9.0.我试图单独做,但得到了同样的错误.

我提到了El Capitan,因为有些人在El Capitan上遇到其他python安装的问题,我想知道这是否是由于这个原因.

有谁知道如何解决这个问题？

Answer 1

以下是我解决问题的方法:

首先,安装Xcode CLI:

xcode-select --install

然后重新安装Python:

sudo brew reinstall python

最后,安装nltk:

sudo pip install -U nltk

希望能帮助到你 :)

Answer 2

我知道那里有很多'酿造助推器',但你不应该使用另一个python来做一些基本的东西.如果pip在/ System中找到依赖关系,正如他们在南方公园所说的那样,你将会度过一个糟糕的时光.如果您不需要在系统范围内进行此更改,则可以pip install --user <package>添加$HOME/Library/Python/2.7/bin到shell路径(通过~/.bash_profile等).

Answer 3

这两个都导致六个版本1.41:

pip install --ignore-installed six

pip install awsebcli --upgrade --ignore-installed six

brew解决方案是有意义的,imo.如果Apple需要自己的El Capitan Python副本,它可以拥有它.我现在在这里:/usr/local/bin/python
