python3-pip does not install Django

I tried to install Django with python3-pip When I run

pip3 install Django or sudo pip3 install Django

It gives this error message

Traceback (most recent call last):

what can I do?!

Solution 1:

You don't need to use pip3 to install Django in Ubuntu 16.04 and later releases because Django is in the default repositories. Open the terminal and type:

sudo apt update  
sudo apt install python3-django    

If you want to install Django using pip3 anyway, you should update pip3 to the latest version in order for pip3 to be able to install Django and its dependencies. Run these commands:

sudo python3 -m pip install --upgrade pip  
sudo python3 -m pip install django  

You can verify that the installation was successful by typing:

django-admin --version
