On linux SUSE or RedHat, how do I load Python 2.7

Asked 10/11, 2010 at 21:41 Answered 4/4, 2018 at 19:46

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.

"RedHat"? You mean Red Hat Enterprise Linux? Which version? – Tonguetied 10/11, 2010 at 21:42

Instructions to download source and install:

https://www.python.org/download/

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.

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).

so I just type those commands into a xterm window, and I am good to go? – Sailcloth 10/11, 2010 at 21:54

+1 for showing the actual commands (dear to any linux person) to untar and 'install' software from source :) – Tertia 10/11, 2010 at 21:55

make install will damage the system Python. Use make altinstall instead. – Tonguetied 10/11, 2010 at 21:57

@Dag: that will download the source for python 2.7, untar it, build it, install it. seeing as you already have python(2.4) on your path, it 'might' mess up just loading the python intrep from xterm by just typing python so you still need to add the proper path/to/python2.7/bin/ to your system path – Tertia 10/11, 2010 at 21:57

OK, so I don't want to mess up the server, but I need to run with at least 2.6 and why not make it 2.7 So from the above commands, what is it that I need to change to make this work? Not very familiar with linux, but I can follow directions. – Sailcloth 10/11, 2010 at 22:6

OK, I did this one except the last step was make altinstall. That seemed to work – Sailcloth 11/11, 2010 at 0:11

How can the system path be change so that python 2.7.* is the default one? – Bead 27/1, 2014 at 16:8

On fresh machine w/o any dev deps, you may need to also do sudo yum install automake gcc – Defalcate 21/5, 2014 at 19:37

how do you make the python 27 install to your system path? So that when I type "python" in terminal or go to install ipython it recognises 2.7. I am on redhat 6.5 and when I type "python --version" I get 2.7.5. But when I sudo python setup.py install I get an error (need 2.7 or above). – Piggery 24/11, 2014 at 22:16

Thank you. The suggested is well and everything went fine. But, after 'altinstall' still python gives the old version. Can you kindly let me know where exactly it does install/upgrade? – Incurable 21/2, 2015 at 17:0

As somebody else already pointed here, software collections are much better solution there. – Nephoscope 25/5, 2015 at 5:7

What if I already did make install? How do I fix? Thanks! – Prison 7/4, 2016 at 6:37

@Jerry pray. Most of default tools, like the regular apt-get relies on the system python. I did that once into an vps and the only way to revert was get backup back. There's no real way to do that unless you really know howto rollback inodes and other hard stuff. In short: pray. – Marsala 2/1, 2017 at 6:8

@Piggery i think that the best approach is to create an alias at user level, meaning at your ./~bashrc file. When you launch things like apt-get as sudo, it will use the python old-system binary, but when you put python on your user's console you'll get the one you created at alias. – Marsala 2/1, 2017 at 6:15

currently python.org/ftp/python/2.7.11/Python-2.7.11.tgz and this is a 2015 release – Unblown 31/10, 2017 at 15:23

@Unblown - It's actually 2.7.14 as the latest release. I don't normally make an attempt to update it, but noticed python.org now supports https so worth an update. – Oratorical 31/10, 2017 at 15:31

@Nephoscope mentioned "software solutions" as a possible solution for this. It's hard to find resources about this that aren't retired or deprecated. Here's one, although any details about using it specifically for Python2.7 are not prominent: softwarecollections.org/en/docs/guide – Sylvan 10/11, 2017 at 15:19

What does scl stand for? Is this repo stable? Like EPEL, does it promise not to interfere with the default system packages? – Henri 10/6, 2013 at 18:39

@StefanLasiewski: scl stands for Software Collections, and yes they do make that promise explicitly (it's actually their very purpose). Introduction. Guide. The repository suggested by YumYumYum is maintained by a Red Hat engineer and targets RHEL6. – Herve 20/11, 2013 at 14:22

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. 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:

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:

sudo rm /usr/local/bin/easy_install

Now I can install libraries for the 2.7 version of Python like this:

sudo /usr/local/bin/easy_install-2.7 numpy

I had to do yum -y install zlib-devel in order to get setuptools to install. – Eichhorn 28/8, 2012 at 22:55

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

It also makes sure you get sqlite and readline support.

Rhoades answered 7/11, 2011 at 9:35 Comment(2)

I also updated this script a bit for what worked for me... gist here: gist.github.com/Brant/9993559 – Cortex 5/4, 2014 at 15:45

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:

http://thebuild.com/blog/2009/10/17/wordpress-to-djangopostgresql-part-3-installing-apache-python-2-6-psycopg2-and-mod_wsgi/

The post is about 2.6, but applies equally to 2.7.

Also this link would work when installing python on RH, leaving python 2.4 as it is: tecadmin.net/install-python-2-7-on-centos-rhel – Haworth 21/7, 2015 at 15:8

Execute the below commands to make yum work as well as python2.7

yum groupinstall -y development
yum groupinstall -y 'development tools'
yum install -y zlib-dev openssl-devel wget sqlite-devel bzip2-devel
yum -y install gcc gcc-c++ numpy python-devel scipy git boost*
yum install -y *lapack*
yum install -y gcc gcc-c++ make bison flex autoconf libtool memcached libevent libevent-devel uuidd libuuid-devel  boost boost-devel libcurl-dev libcurl curl gperf mysql-devel

cd
mkdir srk
cd srk 
wget http://www.python.org/ftp/python/2.7.6/Python-2.7.6.tar.xz
yum install xz-libs
xz -d Python-2.7.6.tar.xz
tar -xvf Python-2.7.6.tar
cd Python-2.7.6
./configure --prefix=/usr/local
make
make altinstall



echo "export PATH="/usr/local/bin:$PATH"" >> /etc/profile
source /etc/profile
mv /usr/bin/python /usr/bin/python.bak
update-alternatives --install /usr/bin/python python /usr/bin/python2.6 1

update-alternatives --config python
sed -i "s/python/python2.6/g" /usr/bin/yum

Yates answered 4/3, 2016 at 16:4 Comment(1)

using altinstall does install it on /usr/local by design. the other way would be use ./configure --prefix=/usr/local then just make install. the system python will remain untouched in both cases. – Marsala 2/1, 2017 at 8:17

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.

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)

Tertia answered 10/11, 2010 at 21:49 Comment(0)

If you can live with 2.6, EPEL has it for RHEL 5 in the python26 package, although you will need to use python2.6 to invoke it since the system will still need python to be 2.4 in order to run.

Tonguetied answered 10/11, 2010 at 21:50 Comment(4)

so on RHEL I have to run with 2 versions of python if I want to run my program that does not work on 2.4? – Sailcloth 10/11, 2010 at 21:53

You must have 2.4 in order for the system to operate within normal expectations. Any number of minor versions can be parallel-installed. – Tonguetied 10/11, 2010 at 21:56

SO how do I parallel install 2.7? – Sailcloth 10/11, 2010 at 22:32

Either build it from source, or get the python26 SRPM and update it to 2.7. – Tonguetied 10/11, 2010 at 22:34

If you need pip and setup tool , please install openssl and opessl-devl before making python2.7

 yum install openssl-devel

Then follow https://mcmap.net/q/325534/-on-linux-suse-or-redhat-how-do-i-load-python-2-7

Then https://pypi.python.org/pypi/setuptools

wget https://bootstrap.pypa.io/ez_setup.py
python2.7 ez_setup.py

Then to install pip

wget https://bootstrap.pypa.io/get-pip.py
python2.7 get-pip.py

Then to install other packages pip2.7 install package_name

If you want to install Python 2.7 on Oracle Linux, you can proceed as follows:

Enable the Software Collection in /etc/yum.repos.d/public-yum-ol6.repo.

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:

yum install gcc libffi libffi-devel python27 python27-python-devel openssl-devel python27-MySQL-python

edit bash_profile with follow variables:

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:

/opt/rh/python27/root/usr/bin/pip install pynacl
/opt/rh/python27/root/usr/bin/python2.7 --version

Tacita answered 27/6, 2017 at 15:45 Comment(0)

If you get an error when at the ./configure stage that says

configure: error: in `/home//Downloads/Python-2.7.14': configure: error: no acceptable C compiler found in $PATH

then try this.

no acceptable C compiler found in $PATH when installing python
