1. Installation Requirements
When using the python framework Django, you need to pay attention to the following
Pycharm version is professional version not community version
Pycharm has configured the python interpreter (generally we are using python3 now)
I am using Pycharm version 2020.1.2
2. Preparations
2.1 Create a new project First we open Pycharm as shown below
Some friends may know how to open this interface, you can do this, open your Pycharm compiler, and then click File -> Close Project in the upper left corner
2.2 Input related configuration
Just follow the prompts in the picture below. After the configuration is complete, click Create
2.3 The project is created
This is installing the Django framework, just wait for a while
The installation is complete as shown below
2.4 View and install Django version
Select Terminal at the bottom of Pycharm and enter: python -m django --version
(pytorch_gpu) D:\python-workspace\tutorial>python -m django --version
3.2
2.5 Start the project
Enter in Terminal: python manage.py runserver
Then the following small error occurs
Traceback (most recent call last):

solution
Find the seeings. py file, and then add: import os to the header of the settings.py file
Execute again: python manage.py runserver
When the above interface appears, the Django project is basically built.
2.6 Solve a little problem
When I started the Django project, I found that the following little prompt appeared in the console
You have 18 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions. Run ‘python manage.py migrate’ to apply them.
I don't understand the reason for this problem, and I will directly give you a solution.
Solution: First Ctrl + C to end the service, execute this command python manage.py migrate
Operations to perform:
Apply all migrations: admin, auth, contenttypes, sessions
Running migrations:

复制代码
This is done.
Digression
In this first year of fast-growing technology, programming is like a ticket to a world of infinite possibilities for many people. In the star lineup of programming languages, Python is like the leading superstar. With its concise and easy-to-understand syntax and powerful functions, it stands out and becomes one of the most popular programming languages in the world.
The rapid rise of Python is extremely beneficial to the entire industry , but " 人红是非多" has caused it to add a lot of criticism, but it still cannot stop its hot development momentum.
Will Python remain relevant and intact for the rest of the next decade? Today, we're going to analyze the facts and dispel some misconceptions.
