Example of running Django 1.7.4 under Python 3.4.2 on Ubuntu 14.04
Hello.
In this example, I'll show one of the ways to launch the current version of Django under fresh Python.
')
Python 3.4.2 | Release Date: 2014-10-13
Django 1.7.4 | January 27, 2015
Virtualenvwrapper and pyenv will be used:
- virtualenvwrapper will work with “system” python2
- use pyenv to install the latest version of python
- use virtualenvwrapper to create a virtual environment with the latest version of Python "inside"
The launch will be performed on Ubuntu 14.04.1 LTS:
After installing Ubuntu, bash is available by default:
Also, by default, 2 versions of Python are pre-installed immediately:
virtualenvwrapper is a convenient wrapper around virtualenv.
To install virtualenvwrapper you need to perform some actions.
Get new Ubuntu package listings:
Install pip:
Install virtualenvwrapper:
Configure virtualenvwrapper:
Create a folder for PROJECT_HOME from the settings above:
Apply settings:
Now we should have available commands virtualenvwrapper, for example:
pyenv is a handy version control utility for Python.
To install pyenv, you must perform some steps.
Install the necessary dependencies:
Install git:
Install pyenv:
We configure pyenv:
Apply settings:
Now we should have the pyenv commands available, for example, you can see the version of the utility:
pyenv provides the ability to install many different versions of Python.
Install Python 3.4.2:
Perform 'rehash' (Rebuild the shim binaries. You need to install a new Python binary):
To view installed versions of Python, you must run:
Now you can create a virtual environment based on Python 3.4.2.
By default, the Python 3.4.2 binary file will be available in '~ / .pyenv / versions /':
Create a virtual environment (and immediately find ourselves “inside” it):
Check the version of Python:
To exit the virtual environment you need to run:
To view all virtual environments you need to run:
You can get back into the virtual environment by running:
To demonstrate the performance of the Django 1.7.4 under Python 3.4.2, launch the Django 'polls' app from the Django Tutorial .
I created a repository that contains the Django Tutorial run and the 'requirements.txt' file.
Go to the folder for PROJECT_HOME from the settings above:
“Clone” the repository that contains the Django Tutorial:
Go to the folder with the project:
“Fix” the project folder for our virtual environment (when the environment is activated, we will go into this folder):
Install Django 1.7.4:
Run the tests:
Run the development server:
