How to do it...

Execute the following steps one by one to prepare pip requirements for your virtual environment Django project:

1. Let's go to the Django project that you have under version control and create a requirements directory with the following text files:

• _base.txt for shared modules
• dev.txt for the development environment
• test.txt for the testing environment
• staging.txt for the staging environment
• production.txt for production

2. Edit _base.txt and add the Python modules that are shared in all environments, line by line:

# requirements/_base.txt
Django~=3.0.4
djangorestframework
-e git://github.com/omab/python-social-auth.git@6b1e301c79#egg=python-social-auth

3. If the requirements of a specific environment are the same as in _base.txt, add the line including _base.txt in the requirements file of that environment, as shown in the following example:

# requirements/production.txt
-r _base.txt

4. If there are specific requirements for an environment, add them after the _base.txt inclusion, as shown in the following code:

# requirements/dev.txt
-r _base.txt
coverage
django-debug-toolbar
selenium

5. You can run the following command in a virtual environment in order to install all of the required dependencies for the development environment (or an analogous command for other environments), as follows:

(env)$ pip install -r requirements/dev.txt
