Answer 1

面臨着同樣的問題與Ubuntu 14.04，python2.7.6和PIP 1.5.4。 我這樣做，

sudo apt-get install --reinstall python2.7 

要重新安裝蟒（雖然不是必要的）

sudo apt-get purge python-pip 

（除去蟒蛇PIP）

wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py 

（從這個下載，這是升級版（9 ））

sudo python get-pip.py 
sudo pip install package-name 

這工作！

Answer 2

更新了2017（Ubuntu的17）

sudo apt-get purge python-pip 
wget https://bootstrap.pypa.io/get-pip.py 
sudo python get-pip.py 
pip --version 
rm get-pip.py
