从 python 2.7 升级 pyhton3 之后，安装 Pip， Numpy 的问题， Pip， Numpy 继续在以前的 2.7 上安装。我怎么才能装在新的 pyhton3 上呢？

$ sudo easy_install pip

我怎么才能装在新的pyhton3上呢？

谢谢啊，现在已经装上了。

但是执行help( )的时候，遇到这样的问题：

>>> help()

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/_sitebuiltins.py", line 102, in __call__
import pydoc

import tokenize
ImportError: bad magic number in 'tokenize': b'\x03\xf3\r\n'

我的系统还差什么东西呢，还是需要怎么设置呢？

anaconda 不折腾。
