1、根据python版本从 https://pypi.python.org/pypi/setuptools 下载对应版本的setuptools。然后，在终端下运行，sudo sh Downloads/setuptools-0.6c11-py2.7.egg
2、安装pip 在终端下运行sudo easy_install pip
3、安装Numpy和matplotlib。运行 sudo pip install -U numpy matplotlib
4、安装pyyaml 和nltk 运行sudo pip install -U pyyaml nltk
Error: No available formula with the name "pip" Homebrew provides pip via: `brew install python`. However you will then have two Pythons installed on your Mac, so alternatively you can install pip via the instructions at: https://pip.readthedocs.org/en/stable/installing/#install-pip
采用：
sudo easy_install pip
记得加sudo
sudo pip install -U pyyaml nltk
会遇到下面的问题：
Installing collected packages: six 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: ...
采用下面的命令安装：
sudo pip install libName --upgrade --ignore-installed six
3.然后用上述同样的方式安装nltk
pip install --upgrade numpy
import sklearn.datasets Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Python/2.7/site-packages/sklearn/__init__.py", line 57, in <module> from .base import clone File "/Library/Python/2.7/site-packages/sklearn/base.py", line 11, in <module> from .utils.fixes import signature File "/Library/Python/2.7/site-packages/sklearn/utils/__init__.py", line 10, in <module> from .murmurhash import murmurhash3_32 File "numpy.pxd", line 155, in init sklearn.utils.murmurhash (sklearn/utils/murmurhash.c:5029) ValueError: numpy.dtype has the wrong size, try recompiling

解决的办法是关闭sip：
重启电脑，在电脑启动时按住command+R，等画面上出现苹果图标，会看到打开了一个实用工具窗口，打开终端，输入：
csrutil disable
重启完毕后，再次在终端输入：sudo pip install -U numpy
就可以成功了，记得一定要加sudo。
5、同理，如果要安装matplotlib：sudo pip install matplotlib
也一定要加sudo
>>>import nltk
>>>nltk.download()
会调出一个对话框:可以进行package的下载
但是呢，一般是下载不成功的。需要手动去下载数据包
（可以联系本文作者要数据包，也可以自己百度一下，会有资源的），之后就可以进行文本的各种实验了。
2、自行python实验
