sudo apt-get install python-pip python-dev build-essential 

sudo pip install --upgrade pip 

sudo pip install --upgrade virtualenv

wget --no-check-certificate https://github.com/pypa/pip/archive/1.5.5.tar.gz

tar -zxf 1.5..tar.gz

cd pip-1.5./

 python setup.py install

然后就可以用pip 安装其他模块了

例如 pip install requests

执行报以下错误：

Traceback (most recent call last):

  File "setup.py", line , in <module>

    from setuptools import setup, find_packages

ImportError: No module named setuptools

解决方法：

wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz

tar zxvf setuptools-.6c11.tar.gz

cd setuptools-.6c11

python setup.py build

python setup.py install

tar zxvf setuptools-.6c11.tar.gz;cd setuptools-.6c11;python setup.py build;python setup.py install
