4trgr

安装python 2.7版本

wget https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tgz
tar zxvf Python-2.7.8.tgz
cd Python-2.7.8
./configure --prefix=/usr/local/python2.7  --with-readlinemake (解决方向键问题) --with-openssl
--with-openssl-devel （安装pip需要）  --with zlib(安装setuptools)需要

make
make install
mv /usr/bin/python /usr/bin/old_python
ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python

yum是python做的，所以
这样操作之后，yum就不能正常了，需要修改yum文件
vim /usr/bin/yum
第一行把 #!/usr/bin/python 改为  #!/usr/bin/old_python

下面继续安装ipython

wget 'https://pypi.python.org/packages/source/i/ipython/ipython-3.1.0.tar.gz#md5=a749d90c16068687b0ec45a27e72ef8f' --no-check-certificate
tar zxvf ipython-3.1.0.tar.gz
cd ipython-3.1.0
python setup.py install
ipthon安装完成


安装setuptools
wget https://pypi.python.org/packages ... 11d7204f8fe940764f4 --no-check-certificate
cd setuptools-18.2
python setup.py install
安装pip

wget http://pypi.python.org/packages/source/p/pip/pip-1.0.tar.gz

python setup.py build
python setup.py install
ln -s /usr/local/python2.7/bin/pip /usr/bin/pip
pip安装完成

用pip 安装测试：pip install flake8
搞定！
