I was having the same issue using the python 2 7  Follow the below steps to upgrade successfully to 3 6  You can also try this one-   See before upgrading version is 2 x  python --version Python 2 7 5  Use below command to upgrade your python to 3 x version-  yum install python3x  replace x with the version number you want   i e  for installing python 3 6 execute  yum install python36  After that if you want to set this python for your default version then in bashrc file add   vi    bashrc      alias python  python3 6   execute bash command to apply the settings  bash   Now you can see the version below  python --version Python 3 6 3

If you are on RHEL and want a Red Hat supported Python  use Red Hat Software collections  RHSCL   The EPEL and IUS packages are not supported by Red Hat   Also many of the answers above point to the CentOS software collections  While you can install those  they aren t the Red Hat supported packages for RHEL     Also  the top voted answer gives bad advice - On RHEL you do not want to change  usr bin python   usr bin python2 because you will likely break yum and other RHEL admin tools  Take a look at  bin yum  it is a Python script that starts with    usr bin python   If you compile Python from source  do not do a make install as root   That will overwrite  usr bin python  If you break yum it can be difficult to restore your system   For more info  see How to install Python 3  pip  venv  virtualenv  and pipenv on RHEL on developers redhat com   It covers installing and using Python 3 from RHSCL  using Python Virtual Environments  and a number of tips for working with software collections and working with Python on RHEL   In a nutshell  to install Python 3 6 via Red Hat Software Collections     su -   subscription-manager repos --enable rhel-7-server-optional-rpms      --enable rhel-server-rhscl-7-rpms   yum -y install  development   yum -y install rh-python36    yum -y install rh-python36-numpy      rh-python36-scipy       rh-python36-python-tools      rh-python36-python-six   To use a software collection you have to enable it   scl enable rh-python36 bash   However if you want Python 3 permanently enabled  you can add the following to your    bashrc and then log out and back in again  Now Python 3 is permanently in your path     Add RHSCL Python 3 to my login environment source scl source enable rh-python36   Note  once you do that  typing python now gives you Python 3 6 instead of Python 2 7   See the above article for all of this and a lot more detail

It is easy to install it manually    Download  there may be newer releases on Python org       wget https   www python org ftp python 3 4 3 Python-3 4 3 tar xz  Unzip    tar xf Python-3      cd Python-3    Prepare compilation      configure  Build    make  Install    make install   OR if you don t want to overwrite the python executable  safer  at least on some distros yum needs python to be 2 x  such as for RHEL6  - you can install python3   as a concurrent instance to the system default with an altinstall     make altinstall    Now if you want an alternative installation directory  you can pass --prefix to the configurecommand   Example  for  installing  Python in  opt local  just add --prefix  opt local    After the make install step  In order to use your new Python installation  it could be  that you still have to add the  prefix  bin to the  PATH and  prefix  lib to the  LD LIBRARY PATH  depending of the --prefix you passed

You can install miniconda  https   conda io miniconda html   That s a bit more than just python 3 7 but the installation is very straightforward and simple   curl https   repo anaconda com miniconda Miniconda3-latest-Linux-x86 64 sh -O sudo yum install bzip2 bash Miniconda3-latest-Linux-x86 64 sh   You ll have to accept the license agreement and choose some options in interactive mode  accept the defaults   I believe it can be also installed silently somehow

In addition to gecco s answer I would change step 3 from     configure   to     configure --prefix  opt python3   Then after installation you could also     ln -s  opt python3 bin python3  usr bin python3   It is to ensure that installation will not conflict with python installed with yum   See explanation I have found on Internet   http   www hosting com support linux installing-python-3-on-centosredhat-5x-from-source

Three steps using Python 3 5 by Software Collections   sudo yum install centos-release-scl sudo yum install rh-python35 scl enable rh-python35 bash   Note that sudo is not needed for the last command  Now we can see that python 3 is the default for the current shell   python --version Python 3 5 1   Simply skip the last command if you d rather have Python 2 as the default for the current shell   Now let s say that your Python 3 scripts give you an error like  usr bin env  python3  No such file or directory  That s because the installation is usually done to an unusual path    opt rh rh-python35 root bin python3   The above would normally be a symlink  If you want python3 to be automatically added to the  PATH for all users on startup  one way to do this is adding a file like   sudo vim  etc profile d rh-python35 sh   Which would have something like      bin bash  PATH  PATH  opt rh rh-python35 root bin    And now after a reboot  if we do  python3 --version   It should just work  One exception would be an auto-generated user like  jenkins  in a Jenkins server which doesn t have a shell  In that case  manually adding the path to  PATH in scripts would be one way to go   Finally  if you re using sudo pip3 to install packages  but it tells you that pip3 cannot be found  it could be that you have a secure path in  etc sudoers  Checking with sudo visudo should confirm that  To temporarily use the standard PATH when running commands you can do  for example   sudo env  PATH  PATH  pip3 --version   See this question for more details   NOTE  There is a newer Python 3 6 by Software Collections  but I wouldn t recommend it at this time  because I had major headaches trying to install Pycurl  For Python 3 5 that isn t an issue because I just did sudo yum install sclo-python35-python-pycurl which worked out of the box
