有人可以提供在SUSE和RedHat上安装python 2.7版所需的步骤吗？它上面的版本就像2.4,我需要至少2.6才能使我的脚本工作.所以在安装之后,我可以在xTerm中键入Python并获得Python 2.7命令行界面.
下载源代码和安装说明:

注意:您应该检查python 2.7.x的最新版本,因为它经常更新.目前(2017年10月),最新版本为2.7.14,虽然此评论将变得陈旧,新版本可能会每6个月左右发布一次.
wget https://www.python.org/ftp/python/2.7.14/Python-2.7.14.tgz # Download tar xvfz Python-2.7.14.tgz # unzip cd Python-2.7.14 # go into directory ./configure make # build su # or 'sudo su' if there is no root user make altinstall
(编辑:make install - >根据Ignacio的评论制作altinstall).
RHEL 6.2使用(有Python 2.6,我需要Python 2.7.3)所以:

编辑:
CentOS 6.x: http://dev.centos.org/centos/6/SCL/x86_64/python27/ $ sudo sh -c 'wget -qO- http://dev.centos.org/centos/6/SCL/scl.repo >> /etc/yum.repos.d/scl.repo' $ scl enable python27 'python --version' python 2.7.5 $ scl enable python27 bash $ python --version Python 2.7.5
通过(使用DR jimbob接受的答案make altinstall)让我最的方式出现,用python2.7在/usr/local/bin,但我还需要安装一些第三方的模块.好处是easy_install从你正在运行的Python版本获取其安装位置,但我发现我仍然需要为Python 2.7安装easy_install,否则我会得到ImportError: No module named pkg_resources.所以我这样做了:
wget http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg sudo -i export PATH=$PATH:/usr/local/bin sh setuptools-0.6c11-py2.7.egg exit
现在我有了easy_install和easy_install-2.7/ usr/local/bin,前者覆盖了系统的2.6版easy_install,所以我把它删除了:
sudo rm /usr/local/bin/easy_install
现在我可以像这样为2.7版本的Python安装库:
sudo /usr/local/bin/easy_install-2.7 numpy
