[英]On linux SUSE or RedHat, how do I load Python 2.7
Can someone provide the steps needed to install python version 2.7 on SUSE and RedHat? 有人可以提供在SUSE和RedHat上安装python 2.7版所需的步骤吗? 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.
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。 So after the install, I can type Python in a xTerm and get the Python 2.7 command line interface.
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。

NOTE: You should check for the latest version of python 2.7.x, as it gets updated frequently. 注意:您应该检查python 2.7.x的最新版本,因为它经常更新。 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.
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。

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 - >根据Ignacio的评论制作altinstall)。

The accepted answer by dr jimbob (using make altinstall
) got me most of the way there, with python2.7
in /usr/local/bin
but I also needed to install some third party modules. jimbob博士(使用
make altinstall
)接受的答案让我大部分都在那里,在/usr/local/bin
使用python2.7
,但我还需要安装一些第三方模块。 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
. 好的是easy_install从你运行的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
。 So I did this: 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_install
and easy_install-2.7
in /usr/local/bin and the former overrides my system's 2.6 version of easy_install, so I removed it: 现在我在/ usr / local / bin中有
easy_install
和easy_install-2.7
,而前者覆盖了系统的2.6版easy_install,所以我删除了它:
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
To install Python 2.7.2 use this script - https://github.com/bngsudheer/bangadmin/blob/master/linux/centos/6/x86_64/build-python-27.sh 要安装Python 2.7.2,请使用此脚本 - https://github.com/bngsudheer/bangadmin/blob/master/linux/centos/6/x86_64/build-python-27.sh

You have to leave Python 2.4 installed on RHEL/Centos; 你必须在RHEL / Centos上安装Python 2.4; otherwise, tools start breaking.
否则,工具开始破碎。 You can do a dual-install, though;
但是你可以进行双重安装; I talk about this here:
我在这里谈到这个:

The post is about 2.6, but applies equally to 2.7. 该职位约为2.6,但同样适用于2.7。
Great thing about linux, you're still able to download the source and on most systems have all of the tools to compile the version yourself. 关于linux的好处,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 ) 为了通过键入
python
从xterm获取python cli,python bin目录必须位于系统路径变量中( Red Hat示例 , Suse示例 )
如果你可以使用2.6, EPEL在python26
包中使用RHEL 5,虽然你需要使用python2.6
来调用它,因为系统仍然需要python
为2.4才能运行。
If you need pip and setup tool , please install openssl and opessl-devl before making python2.7 如果你需要pip和setup工具,请在制作python2.7之前安装openssl和opessl-devl
yum install openssl-devel
Then follow https://stackoverflow.com/a/4149444/429476 然后按照https://stackoverflow.com/a/4149444/429476进行操作
Then https://pypi.python.org/pypi/setuptools 然后https://pypi.python.org/pypi/setuptools
wget https://bootstrap.pypa.io/ez_setup.py
python2.7 ez_setup.py
Then to install pip 然后安装点子
wget https://bootstrap.pypa.io/get-pip.py
python2.7 get-pip.py
Then to install other packages pip2.7 install package_name 然后安装其他软件包pip2.7 install package_name
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: 在对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: 使用跟随变量编辑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:
/opt/rh/python27/root/usr/bin/pip install pynacl
/opt/rh/python27/root/usr/bin/python2.7 --version
If you get an error when at the ./configure stage that says 如果在./configure阶段出现错误
configure: error: in `/home//Downloads/Python-2.7.14': configure: error: no acceptable C compiler found in $PATH
configure:error:在`/home//Downloads/Python-2.7.14'中:configure:错误:在$ PATH中找不到可接受的C编译器
then try this. 然后尝试这个。
no acceptable C compiler found in $PATH when installing python 安装python时在$ PATH中找不到可接受的C编译器
