Python升级2.4到2.7

Python升级 # yum install gcc gcc-c++.x86_64 compat-gcc-34-c++.x86_64 openssl-devel.x86_64 zlib*.x86_64 # wget http://www.python.org/ftp/python/2.7/Python-2.7.tar.bz2 # tar -xvjf Python-2.7.tar.bz2 # cd Python* # ./configure --PRefix=/opt/python27 # make # make install #vi ~/.bash_profile 

这时候Python已经升级好了，但是默认的Python版本还是2.4.3 

# mv /usr/bin/python /usr/bin/python_backup # ln -s /opt/python27/bin/python /usr/bin/ # python -V Python 2.7 这个时候yum又不能用了 # vim /usr/bin/yum #!/usr/bin/python 改成 #!/usr/bin/python2.4

这时候yum修复了，下面就是安装easy_install，pip和requests

# curl -O http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg # chmod 775 setuptools-0.6c11-py2.7.egg # sh setuptools-0.6c11-py2.7.egg # curl -O http://pypi.python.org/packages/source/p/pip/pip-1.0.tar.gz # tar xvfz pip-1.0.tar.gz # cd pip-1.0 # python setup.py install
