To mention that a few minutes ago I installed django on a wrong folder and everything worked.. Please help! Thank you!

回答1:

In the main directory root add the following command to create the environment:

$ python3 -m venv venv this code will create a folder called venv in the root. Which basically is the virtual environment folder.

Then add the following command to activate the virtual environment:

$ source venv/bin/activate

your_project_folder/
 |
 |-- your_main_app_folder/
 |         |
 |         |--Folder_with_controllers/
 |         |            settings.py
 |         |            urls.py
 |         |            ...
 |         | 
 |         |--App_folder/
 |         |--Other_app_folder/
 |
 |--venv/

If the code works fine your bash should look like this: (venv) <the_path_for_the_folder> your_project_folder %

After activated your environment you can now install django and other packages.

Ps: make sure you instal and activate the virtual environment folder not in the your_main_app_folder.
