Learn how to create django Before project construction , We need to understand the virtual environment first （virtual environment） This thing
Popular speaking , When developing multiple projects , Each project has its own modules , We can't put them all in one place , For example, I used in this project django The version is 2.2, And the version used in the other project does 3.1, That would create chaos , It is not convenient for the packaging and release of products . Virtual environment can be understood as a small square in a large wardrobe , You put down your clothes for tomorrow in this square , Put down your daily allowance in another box .
First of all, make sure that our computer is installed with Python Of , And the system environment variables of the computer （ My computer — Right click , attribute — Advanced system setup — environment variable ） Configured Python The path of 
If there is , It proves that we have the ability to install python Virtual environment conditions ！ It shows that it has been successful 1/4.
Next , Prepare a folder , Used to store our Django Engineering documents , Create a new folder in this folder , Name yourself .
Open the system terminal 
For example, I store my system D disc ：
Input d： After entering D disc , Then input cd Python/Django/one The yellow font is the location of my project folder 
What we need to do next is to create a virtual environment under this path , In the future, when we create another project, we can create a virtual environment in the new folder
Installing a virtual environment
Enter... In the current path pip3 install virtualenv（ If the computer has only python3, be 3 No , Direct input pip install virtualenv）
When the loading is completed, the download is successful ！
Next, enter... Under the path ：
two Environment name , Unfixed , Just remember , Something will jump out , It indicates that the creation is successful 
Then the name of your newly created virtual environment will appear in front of the original path 
To exit the virtual environment, enter ：deactivate that will do

python manage.py runserver You can see the following 
python manage.py runserver 9000 Successfully created django project , We might think , Where do I write my code ？
Of course not at the terminal , It's too hard . We use it pycharm,pycharm The powerful prompt function can bring great convenience to our development .
You can download it from the official website , Community Edition is fine , But it's best to have a professional version , In this way, the above steps of more than 3000 words can be directly omitted , It's just pycharm The activation of the professional version is a little troublesome , Many students may have wanted to give up when they activated ！ Because it is more metaphysical , And the community version can solve the problem , So I won't go into details here .
