简介:
记录一下关于 Python 环境软件包的一些安装步骤
1、升级 Python 到 2.7.10( 默认 2.6.6 )
shell > yum -y install epel-releaseshell > yum -y install gcc wget readline-devel zlib-devel openssl-develshell > wget https://www.python.org/ftp/python/2.7.10/Python-2.7.10.tgzshell > tar zxf Python-2.7.10.tgzshell > cd Python-2.7.10 ; ./configure --prefix=/usr/local/python2.7 ; make ; make installshell > mv /usr/bin/python /usr/bin/old_pythonshell > ln -s /usr/local/python2.7/bin/python /usr/bin/pythonshell > sed -i '1s/python/old_python/' /usr/bin/yumshell > python -VPython 2.7.10
## 这样就实现的 python 的升级
## readline-devel 这个包要事先安装,不然后面的 ipython 不支持 tab 、方向键等,还要重新编译 python
## zlib-devel 这个包 Setuptools 会用到,openssl-devel 这个包 pip 会用到
## /usr/bin/yum 文件解释器要改一下,不然无法使用 yum
2、安装 Setuptools
shell > wget https://pypi.python.org/packages/source/s/setuptools/setuptools-15.2.tar.gz#md5=a9028a9794fc7ae02320d32e2d7e12eeshell > tar zxf setuptools-15.2.tar.gzshell > cd setuptools-15.2 ; python setup.py installshell > ln -s /usr/local/python2.7/bin/easy_install /usr/bin/easy_install
## 这样 Setuptools 也安装好了,如果不安装这个包直接下载 pip 源码包安装可能会报错说找不到 Setuptools
3、安装 pip
shell > wget https://pypi.python.org/packages/source/p/pip/pip-6.1.1.tar.gz#md5=6b19e0a934d982a5a4b798e957cb6d45shell > tar zxf pip-6.1.1.tar.gzshell > cd pip-6.1.1 ; python setup.py installshell > ln -s /usr/local/python2.7/bin/pip /usr/bin/pip
## 这样 pip 也安装好了,当然,有了 easy_install 就可以直接 easy_install pip 了,源码只是另外一种安装方式
4、安装 ipython
shell > wget https://pypi.python.org/packages/source/i/ipython/ipython-3.1.0.tar.gz#md5=a749d90c16068687b0ec45a27e72ef8fshell > tar zxf ipython-3.1.0.tar.gzshell > cd ipython-3.1.0 ; python setup.py installshell > ln -s /usr/local/python2.7/bin/ipython /usr/bin/ipython
## 这样 ipython 也安装好了,同样可以通过 pip install ipython 来快速安装
