我必须将Python3.4.1用于软件，因此我从源代码安装它。现在我使用easy_install安装了pip后出现了这个错误：
bash-4.3$ python
Python 3.4.1 (default, Aug 4 2016, 13:53:56)

bash-4.3$ pip -V
pip 8.1.2 from /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages (python 3.4)
bash-4.3$ python --version
Python 3.4.1
如何在OSX EL Capitan中为此版本的Python安装numpy？
bash-4.3$ pip freeze | grep numpy
numpy==1.11.1
更新：我甚至尝试过这种方法，但仍无法导入：
bash-4.3$ wget https://bootstrap.pypa.io/get-pip.py

还有我在另一篇SO帖子中看到的另一个建议：
bash-4.3$ python3 -m pip
/usr/local/bin/python3: No module named pip
