Ошибка django modulenotfounderror no module named

In this Python Django Tutorial, we will discuss how to solve the ModuleNotFoundError: no module named Django, and we shall also cover the following topics:

• No module named Django windows 10
• No module named Django ubuntu
• No module named Django macOS

No module named Django windows 10

In this section, we will learn how to solve the modulenotfounderror: no module named ‘django’ in windows 10.

For this, firstly check whether you have pip installed or not, by simply writing the command pip in the python terminal. If you have then it’s fine, otherwise, from the internet download a python script called get-pip.py and save it to your local system.

Command:

# Check pip is installed or not

pip

Pip is the package insatller used to install packages from the Python Packages.

Try to be aware of location the file was saved and change the current directory from the command prompt to that location.

#If pip is not installed then

cd path_of_dir_of_get-pip_script

After this, install pip and run the get-pip.py script by writing the following command:

"python .get-pip.py"

Now, to install Django with its dependencies type the following command:

pip install django

Your, error will be resolved. Or, if not resolved then check the following steps.

• If you installed Django in a virtual environment, make sure it must be activated.

source venv/bin/activate

• Make sure the Django version you’re installing is compatible with the Python version you have installed.
• If you have a 64-bit version of Python installed, ensure sure Django is 64-bit as well. In the case of 32 bits, both must be 32 bits.
• Make sure to include the path to Python in the PATH variable for system and environment variables.
• Upgrade pip to the most recent version if it is out of date.

python -m pip install --upgrage pip

• Make sure there are no errors in the import statement as well.

A common error you may encounter when using Python is modulenotfounderror: no module named ‘django’.

This error occurs when the Python interpreter cannot detect the Django library in your current environment.

You can install Django in Python 3 with python -m pip install django.

This tutorial goes through the exact steps to troubleshoot this error for the Windows, Mac and Linux operating systems.

ModuleNotFoundError: no module named ‘django’

What is ModuleNotFoundError?

The ModuleNotFoundError occurs when the module you want to use is not present in your Python environment. There are several causes of the modulenotfounderror:

The module’s name is incorrect, in which case you have to check the name of the module you tried to import. Let’s try to import the re module with a double e to see what happens:

import ree

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
1 import ree
ModuleNotFoundError: No module named 'ree'

To solve this error, ensure the module name is correct. Let’s look at the revised code:

import re
print(re.__version__)

2.2.1

You may want to import a local module file, but the module is not in the same directory. Let’s look at an example package with a script and a local module to import. Let’s look at the following steps to perform from your terminal:

mkdir example_package
cd example_package
mkdir folder_1
cd folder_1
vi module.py

Note that we use Vim to create the module.py file in this example. You can use your preferred file editor, such as Emacs or Atom. In module.py, we will import the re module and define a simple function that prints the re version:

import re
def print_re_version():
    print(re.__version__)

Close the module.py, then complete the following commands from your terminal:

cd ../
vi script.py

Inside script.py, we will try to import the module we created.

import module
if __name__ == '__main__':
    mod.print_re_version()

Let’s run python script.py from the terminal to see what happens:

Traceback (most recent call last):
  File "script.py", line 1, in ≺module≻
    import module
ModuleNotFoundError: No module named 'module'

To solve this error, we need to point to the correct path to module.py, which is inside folder_1. Let’s look at the revised code:

import folder_1.module as mod
if __name__ == '__main__':
    mod.print_re_version()

When we run python script.py, we will get the following result:

2.2.1

Lastly, you can encounter the modulenotfounderror when you import a module that is not installed in your Python environment.

What is Django?

Django is a high-level framework for building web applications hat encourages rapid development and clean, pragmatic design.

The simplest way to install Django is to use the package manager for Python called pip. The following installation instructions are for the major Python version 3.

Always Use a Virtual Environment to Install Packages

It is always best to install new libraries within a virtual environment. You should not install anything into your global Python interpreter when you develop locally. You may introduce incompatibilities between packages, or you may break your system if you install an incompatible version of a library that your operating system needs. Using a virtual environment helps compartmentalize your projects and their dependencies. Each project will have its environment with everything the code needs to run. Most ImportErrors and ModuleNotFoundErrors occur due to installing a library for one interpreter and using the library with another interpreter. Using a virtual environment avoids this. In Python, you can use virtual environments and conda environments. We will go through how to install Django with both.

How to Install Django on Windows Operating System

First, you need to download and install Python on your PC. Ensure you select the install launcher for all users and Add Python to PATH checkboxes. The latter ensures the interpreter is in the execution path. Pip is automatically on Windows for Python versions 2.7.9+ and 3.4+.

You can check your Python version with the following command:

python3 --version

You can install pip on Windows by downloading the installation package, opening the command line and launching the installer. You can install pip via the CMD prompt by running the following command.

python get-pip.py

You may need to run the command prompt as administrator. Check whether the installation has been successful by typing.

pip --version

Django installation on Windows Using pip

To install Django, first, create the virtual environment. The environment can be any name, in this we choose “env”:

virtualenv env

You can activate the environment by typing the command:

envScriptsactivate

You will see “env” in parenthesis next to the command line prompt. You can install Django within the environment by running the following command from the command prompt.

python3 -m pip install django

We use python -m pip to execute pip using the Python interpreter we specify as Python. Doing this helps avoid ImportError when we try to use a package installed with one version of Python interpreter with a different version. You can use the command which python to determine which Python interpreter you are using.

How to Install Django on Mac Operating System using pip

Open a terminal by pressing command (⌘) + Space Bar to open the Spotlight search. Type in terminal and press enter. To get pip, first ensure you have installed Python3:

python3 --version

Python 3.8.8

Download pip by running the following curl command:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

The curl command allows you to specify a direct download link. Using the -o option sets the name of the downloaded file.

Install pip by running:

python3 get-pip.py

To install Django, first create the virtual environment:

python3 -m venv env

Then activate the environment using:

source env/bin/activate 

You will see “env” in parenthesis next to the command line prompt. You can install Django within the environment by running the following command from the command prompt.

python3 -m pip install django

How to Install Django on Linux Operating Systems

All major Linux distributions have Python installed by default. However, you will need to install pip. You can install pip from the terminal, but the installation instructions depend on the Linux distribution you are using. You will need root privileges to install pip. Open a terminal and use the commands relevant to your Linux distribution to install pip.

Installing pip for Ubuntu, Debian, and Linux Mint

sudo apt install python-pip3

Installing pip for CentOS 8 (and newer), Fedora, and Red Hat

sudo dnf install python-pip3

Installing pip for CentOS 6 and 7, and older versions of Red Hat

sudo yum install epel-release
sudo yum install python-pip3

Installing pip for Arch Linux and Manjaro

sudo pacman -S python-pip

Installing pip for OpenSUSE

sudo zypper python3-pip

Django installation on Linux with Pip

To install Django, first create the virtual environment:

python3 -m venv env

Then activate the environment using:

source env/bin/activate 

You will see “env” in parenthesis next to the command line prompt. You can install Django within the environment by running the following command from the command prompt.

Once you have activated your virtual environment, you can install Django using:

python3 -m pip install django

Installing Django Using Anaconda

Anaconda is a distribution of Python and R for scientific computing and data science. You can install Anaconda by going to the installation instructions. Once you have installed Anaconda, you can create a virtual environment and install Django.

To create a conda environment, you can use the following command:

conda create -n django-project python=3.8

You can specify a different Python 3 version if you like. Ideally, choose the latest version of Python. Next, you will activate the project container. You will see “django-project” in parentheses next to the command line prompt.

source activate django-project

Now you’re ready to install Django using conda.

Once you have activated your conda environment, you can install Django using the following command:

conda install -c conda-forge django

Check Django Version

Once you have successfully installed Django, you can check its version. If you used pip to install Django, you can use pip show from your terminal.

python3 -m pip show django

Name: Django
Version: 4.0.2
Summary: A high-level Python web framework that encourages rapid development and clean, pragmatic design.

Second, within your python program, you can import the Django and then reference the __version__ attribute:

import django
print(django.__version__)

4.0.2

If you used conda to install Django, you could check the version using the following command:

conda list -f django

# Name                    Version                   Build  Channel
django                    4.0.2            py38h50d1736_0    conda-forge

Summary

Congratulations on reading to the end of this tutorial. The modulenotfounderror occurs if you misspell the module name, incorrectly point to the module path or do not have the module installed in your Python environment. If you do not have the module installed in your Python environment, you can use pip to install the package. However, you must ensure you have pip installed on your system. You can also install Anaconda on your system and use the conda install command to install Django.
