ModuleNotFoundError: No module named 'jwt' in Python

ModuleNotFoundError: No module named 'jwt' in Python #

The Python "ModuleNotFoundError: No module named 'jwt'" occurs when we forget to install the PyJWT module before importing it or install it in an incorrect environment. To solve the error, install the module by running the pip install PyJWT command.

Open your terminal in your project's root directory and install the PyJWT module.

Copied!
# 👇️ in a virtual environment or using Python 2
pip install PyJWT

# 👇️ for python 3 (could also be pip3.10 depending on your version)
pip3 install PyJWT

# 👇️ if you get permissions error
sudo pip3 install PyJWT

# 👇️ if you don't have pip in your PATH environment variable
python -m pip install PyJWT

# 👇️ for python 3 (could also be pip3.10 depending on your version)
python3 -m pip install PyJWT

# 👇️ for Anaconda
conda install -c conda-forge pyjwt

After you install the PyJWT package, try importing it like:

Copied!
import jwt

encoded = jwt.encode({"some": "payload"}, "secret", algorithm="HS256")

print(encoded)

print(jwt.decode(encoded, "secret", algorithms=["HS256"]))

The Python error "ModuleNotFoundError: No module named 'jwt'" occurs for multiple reasons:

1. Not having the PyJWT package installed by running pip install PyJWT.
2. Installing the package in a different Python version than the one you're using.
3. Installing the package globally and not in your virtual environment.
4. Your IDE running an incorrect version of Python.
5. Naming your module jwt.py which would shadow the official module.
6. Declaring a variable named jwt which would shadow the imported variable.

If the error persists, get your Python version and make sure you are installing the package using the correct Python version.

Copied!
python --version

For example, my Python version is 3.10.4, so I would install the PyJWT package with pip3.10 install PyJWT.

Copied!
pip3.10 install PyJWT

# 👇️ if you get permissions error use pip3 (NOT pip3.X)
sudo pip3 install PyJWT

Notice that the version number corresponds to the version of pip I'm using.

If the PATH for pip is not set up on your machine, replace pip with python3 -m pip:

Copied!
# 👇️ make sure to use your version of Python, e.g. 3.10
python3 -m pip install PyJWT

If the "No module named 'jwt'" error persists, try restarting your IDE and development server / script.

You can check if you have the PyJWT package installed by running the pip show PyJWT command.

Copied!
# 👇️ check if you have PyJWT installed
pip3 show PyJWT

# 👇️ if you don't have pip setup in PATH
python3 -m pip show PyJWT

The pip show PyJWT command will either state that the package is not installed or show a bunch of information about the package, including the location where the package is installed.

If the package is not installed, make sure your IDE is using the correct version of Python.

For example, In VSCode, you can press CTRL + Shift + P or (⌘ + Shift + P on Mac) to open the command palette.

Then type "Python select interpreter" in the field.

Then select the correct python version from the drop down menu.

If you are using a virtual environment, make sure you are installing PyJWT in your virtual environment and not globally.

You can try creating a virtual environment if you don't already have one.

Copied!
# 👇️ use correct version of Python when creating VENV
python3 -m venv venv

# 👇️ activate on Unix or MacOS
source venv/bin/activate

# 👇️ activate on Windows (cmd.exe)
venv\Scripts\activate.bat

# 👇️ activate on Windows (PowerShell)
venv\Scripts\Activate.ps1

# 👇️ install PyJWT in virtual environment
pip install PyJWT

Your virtual environment will use the version of Python that was used to create it.

You also shouldn't be declaring a variable named jwt as that would also shadow the original module.

If the error is not resolved, try to uninstall the PyJWT package and then install it.

Copied!
# 👇️ check if you have PyJWT installed
pip3 show PyJWT

# 👇️ if you don't have pip setup in PATH
python3 -m pip show PyJWT

# 👇️ uninstall PyJWT
pip3 uninstall PyJWT

# 👇️ if you don't have pip setup in PATH
python3 -m pip uninstall PyJWT

# 👇️ install PyJWT
pip3 install PyJWT

# 👇️ if you don't have pip setup in PATH
python3 -m pip install PyJWT

Try restarting your IDE and development server / script.

You can also try to upgrade the version of the PyJWT package.

Copied!
pip3 install PyJWT --upgrade

# 👇️ if you don't have pip setup in PATH
python3 -m pip install PyJWT --upgrade
