这里我的问题有两点。我试图安装BeautifulSoup,但面临以下错误:安装BeautifulSoup时出错

有人可以告诉我我在做什么错在这里?
我的下一个问题与前一个问题有关。我已经安装了Python 3.5.2
>>> print(sys.version)
3.5.2 (v3.5.2:4def2a2901a5, Jun 26 2016, 10:47:25)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)]
>>>
但是在终端上就说明我一个不同的版本:
所以,当我尝试安装BeautifulSoup它开始指向到Python 2.7,我认为是错误的。它应该指向最新的Python版本,即3.5.2
另外,我已经预装了Python 2.7,编号为/usr/bin/python
,Python 3.5.2安装在/usr/local/bin/python
。 如何默认Python版本,使得每次我打开我的终端时它已经指向的Python 3.5.2
