Ubuntu14.04安装pip及配置

安装pip:

wget https://bootstrap.pypa.io/get-pip.py  --no-check-certificate
sudo python get-pip.py

建立软连接：

ln -s /usr/local/bin/pip  /usr/bin/pip

如果用apt-get install python-pip 有可能出现如下问题：

Exception:
Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/pip/basecommand.py", line 122, in main
status = self.run(options, args)

url = finder.find_requirement(req_to_install, upgrade=self.upgrade)
File "/usr/lib/python2.7/dist-packages/pip/index.py", line 252, in find_requirement

session=self.session,
File "/usr/lib/python2.7/dist-packages/pip/index.py", line 670, in get_page
resp = session.get(url, headers={"Accept": "text/html"})

pip配置豆瓣源：
