python2.7 oracle安装教程,升级 Python到2.7 并安装 IPython

㈠ Python 依赖包

# rpm -q gcc gdbm-devel readline-devel ncurses-devel zlib-devel bzip2-develsqlite-devel db4-devel openssl-devel tk-devel bluez-libs-devel make --qf \'%{name}.%{arch}\n\'|sort

㈡ 安装 Python 2.7

# wget

# tar -zxv -f Python-2.7.3.tar.bz2

# cd Python-2.7.3

# ./configure

# make && make install

# cd /usr/local/lib/python2.7  /*默认安装目录在/usr/local/lib/python2.7*/

# /usr/local/bin/python -V     /*查看一下刚才安装的版本 /usr/local/bin/python -V，看到了 2.7*/

# mv /usr/bin/python /usr/bin/python.bak /*备份！！！*/

# ln -sf /usr/local/bin/python2.7 /usr/bin/python /*把系统默认的Python指向刚才安装的Python2.7*/

# python -V

使用yum的话会发现出错，这是因为yum 依赖2.4.3而现在默认的 Python 版本是 2.7

# yum list | grep gcc

There was a problem importing one of the Python modules

required to run yum. The error leading to this problem was:

No module named yum

# vim /usr/bin/yum

将首行显示的 #!/usr/bin/python 修改为 #!/usr/bin/python2.4或者2.3、总之、自己要去/usr/bin目录下实地考察、确认是哪个才行、网上都是2.4啊、这估计是抄来抄去的结果

㈢ 安装 IPython

# wget

# tar -zxv -f ipython-0.13.2.tar.gz

# cd ipython-0.13.2

# python setup.py install  /*这里需要注意的是、Python的版本最好比较高、否则这步容易出错*/

# ln -sf /usr/local/bin/ipython /usr/bin/ipython /*做不做无所谓*/
