On linux SUSE or RedHat, how do I load Python 2.7
提问by Dag
Can someone provide the steps needed to install python version 2.7 on SUSE and RedHat? It version that is on there is like 2.4 and I need to have it at at least 2.6 to make my script work. So after the install, I can type Python in a xTerm and get the Python 2.7 command line interface.
有人可以提供在 SUSE 和 RedHat 上安装 python 2.7 版所需的步骤吗？那里的版本就像 2.4，我需要至少 2.6 才能使我的脚本工作。因此，安装后，我可以在 xTerm 中键入 Python 并获得 Python 2.7 命令行界面。

NOTE: You should check for the latest version of python 2.7.x, as it gets updated frequently. Currently (Oct 2017), the latest version is 2.7.14 though this comment will get old and new versions likely will be released every 6 months or so.
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），最新版本是 2.7.14，尽管此评论会变旧，新版本可能每 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
(EDIT: make install -> make altinstall per Ignacio's comment).
（编辑：make install -> make altinstall 根据 Ignacio 的评论）。

Great thing about linux, you're still able to download the sourceand on most systems have all of the tools to compile the version yourself.
linux 的一大优点是，您仍然可以下载源代码，并且在大多数系统上都有自己编译版本的所有工具。
In order to get a python cli from xterm just by typing python, the python bin directory must be in your system path variable (Red Hat example, Suse example)
为了仅通过键入从 xterm 获取 python cli python，python bin 目录必须在您的系统路径变量中（Red Hat 示例、Suse 示例）

You have to leave Python 2.4 installed on RHEL/Centos; otherwise, tools start breaking. You can do a dual-install, though; I talk about this here:
你必须在 RHEL/Centos 上安装 Python 2.4；否则，工具开始损坏。不过，您可以进行双重安装；我在这里谈这个：
The post is about 2.6, but applies equally to 2.7.
该职位大约为 2.6，但同样适用于 2.7。

The accepted answer by dr jimbob (using make altinstall) got me most of the way there, with python2.7in /usr/local/binbut I also needed to install some third party modules. The nice thing is that easy_install gets its installation locations from the version of Python you are running, but I found I still needed to install easy_install for Python 2.7 otherwise I would get ImportError: No module named pkg_resources. So I did this:
jimbob 博士（使用make altinstall）接受的答案让我在那里完成了大部分工作python2.7，/usr/local/bin但我还需要安装一些第三方模块。好消息是 easy_install 从您正在运行的 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
Now I have easy_installand easy_install-2.7in /usr/local/bin and the former overrides my system's 2.6 version of easy_install, so I removed it:
现在我已经easy_install和easy_install-2.7在/ usr / local / bin目录和前覆盖我的系统的2.6版中的easy_install，所以我删除它：
sudo rm /usr/local/bin/easy_install
Now I can install libraries for the 2.7 version of Python like this:
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

If you want to install Python 2.7 on Oracle Linux, you can proceed as follows:
如果要在 Oracle Linux 上安装 Python 2.7，可以按以下步骤操作：
Enable the Software Collection in /etc/yum.repos.d/public-yum-ol6.repo.
在 /etc/yum.repos.d/public-yum-ol6.repo 中启用软件集合。
vim /etc/yum.repos.d/public-yum-ol6.repo
[public_ol6_software_collections]
name=Software Collection Library release 1.2 packages for Oracle Linux 6
(x86_64)
baseurl=[http://yum.oracle.com/repo/OracleLinux/OL6/SoftwareCollections12/x86_64/][1]
gpgkey=file:[///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle][2]
gpgcheck=1
enabled=1 <==============change from 0 to 1
After making this change to the yum repository you can simply run the yum command to install the Python:
对 yum 存储库进行此更改后，您只需运行 yum 命令即可安装 Python：
yum install gcc libffi libffi-devel python27 python27-python-devel openssl-devel python27-MySQL-python
edit bash_profile with follow variables:
使用以下变量编辑 bash_profile：
vim ~/.bash_profile
PATH=$PATH:$HOME/bin:/opt/rh/python27/root/usr/bin export PATH
LD_LIBRARY_PATH=/opt/rh/python27/root/usr/lib64 export LD_LIBRARY_PATH
PKG_CONFIG_PATH=/opt/rh/python27/root/usr/lib64/pkgconfig export PKG_CONFIG_PATH
Now you can use python2.7 and pip for install Python modules:
现在你可以使用 python2.7 和 pip 来安装 Python 模块了：
/opt/rh/python27/root/usr/bin/pip install pynacl
/opt/rh/python27/root/usr/bin/python2.7 --version
