Prerequisites
- RHEL 6 or 7 server up and running
- Sudo or root priviledged user
Install the necessary utilities
Make sure you have the prerequisites
sudo yum update sudo yum install yum-utils sudo yum groupinstall development
Install Python 3.6
The standard yum repositories does not the latest Python release (as of this writing), so lets install an additional repository, called IUM (Inline with Upstream Stable) toprovide the necessary RPM packages.
Install IUM repository:
sudo yum install https://centos7.iuscommunity.org/ius-release.rpm
Now install python36
sudo yum install python36u
Check the Python version with (should return Python 3.6.1
at the time of writing):
python3.6 -V
Lets use pip to manage Python packages, and some development packages.
sudo yum install python36u-pip
sudo yum install python36u-devel
Show the versions of python installed
# Return the system Python version
python –V
Python 2.7.5
# Now show Python 3 version
python3.6 –V
Python 3.6.1
Installing pip for python 3.6
# First command requires you to have enabled EPEL for CentOS7 sudo yum install python36-setuptools sudo easy_install pip
Installing pip on CentOS 7 for Python 3.x
Assuming you installed Python 3.4 from EPEL, you can install Python 3’s setup tools and use it to install pip.
# First command requires you to have enabled EPEL for CentOS7
sudo yum install python34-setuptools sudo easy_install pip # use which "pip3.6" and "which python3.6" to find the path, yes it should be in bin # unfortunately - lots of stuff depends on the old version, we cannot remove the old, so we have to explicitly state pip3.6 and python3.6 [root@lamp74 bin]# /bin/pip3.6 --version pip 9.0.1 from /usr/lib/python3.6/site-packages (python 3.6) [root@lamp74 bin]# /bin/python3.6 --version Python 3.6.4
If your Unix/Linux distro doesn’t have it in package repos then install using the manual way detailed below.
The manual way to install pip3.6
If you want to do it the manual way, the now-recommended method is to install using the get-pip.py script from pip’s installation instructions.
Install pip
To install pip, securely download get-pip.py
Then run the following (which may require administrator access):
python get-pip.py
If setuptools is not already installed, get-pip.py will install setuptools for you.
Creating a virtualenv – isolate your project with a specific version of python
The preferred way to create a new virtualenv in Python 3 is to run (in your project directory):
python3.6 -m venv myvenv
To activate the virtualenv and start installing packages with pip:
. venv/bin/activate pip install [package_name] pip install -r requirements.txt
