Hi developer, welcome to chapter 1 of building Support Ticketing in Django, if you haven’t known what this series is about please read chapter 0.  In this post, we will be installing Django. Before we install Django we need to have python installed you can check this out if you haven’t installed Python yet. We also need virtual environment( not necessary but very important)

What is a virtual environment?

Virtual environment isolates your python or Django projects’ environment per project meaning each project will have its own environment, This is important, Imagine a situation where you have been using Django 2.2.1 for your projects then you get a contract and your teammates have been using Django 3.0 and now you have to use your same machine with your projects. To be tidy I would use a virtual environment to separate all the environments. We will use Virtual environment here

That said let us create a folder where our project will be. in windows, you can create a new folder anywhere you like same to Linux or use the command which creates and cd into the new folder

symons@symons-macbookair:~$ mkdir STICKETING
symons@symons-macbookair:~$ cd STICKETING

 

After you are in the folder you should now open terminal or cd into that folder. Use the following command to create virtual environment  called venv ( you can name it anything you like just change the second venv)

symons@symons-macbookair:~/STICKETING$ python3 -m venv venv

On windows:

python -m venv venv

 

The above command should create a folder in STICKETING directory. Now  we need to activate our venv

symons@symons-macbookair:~/STICKETING$ source venv/bin/activate (venv) 
symons@symons-macbookair:~/STICKETING$

 

Windows

venv\Scripts\activate

 

You will know venv is activated when the next prompt is prefixed with (venv).

Installing Django

Now that we have isolated environment for our S-ticketing environment we can install Django in it. With venv activated let us update pip which is a package installer for python, it will help us install Django. 

python -m pip install --upgrade pip

 

You should see output similar to the following

(venv) symons@symons-macbookair:~/STICKETING$ python -m pip install --upgrade 
pip Cache entry deserialization failed, entry ignored Collecting pip Using cached

 Uninstalling pip-9.0.1: 
Successfully uninstalled pip-9.0.1 
Successfully installed pip-20.0.2

 

Now Install Django. You can leave the version to install the latest version pip install Django

pip install Django~=2.2.4

 

Results:

(venv) symons@symons-macbookair:~/STICKETING$ pip install Django~=2.2.4

(venv) symons@symons-macbookair:~/STICKETING$

 

Django is now installed let us check to confirm

(venv) symons@symons-macbookair:~/STICKETING$ django-admin --version 2.2.10

Done!

See you in chapter 2
