ModuleNotFoundError: No module named 'jwt'

ModuleNotFoundError: No module named 'jwt'

TL;DR: the import is jwt but the pip package is PyJWT. Run python -m pip install PyJWT. If it is already installed, your pip and python are different interpreters; python -m pip fixes that too.

ModuleNotFoundError: No module named 'jwt'

The fix

1. Install with the same interpreter that runs your code:

python -m pip install PyJWT
python -c "import jwt; print(jwt.__version__)"

Success check: prints a version like 2.8.0.

2. If it says already satisfied but the import still fails, you have two Pythons:

python -c "import sys; print(sys.executable)"
python -m pip show PyJWT | grep Location

The Location must sit under the same prefix as sys.executable. If not, reinstall into the right one with python -m pip.

3. If you need RSA/ECDSA support, install the crypto extra: python -m pip install "PyJWT[crypto]".

When this applies

• import jwt fails right after a fresh clone or in a new venv/CI container.
• A tutorial told you to pip install jwt, which installs an unrelated dead package.

When it does NOT apply

• ImportError: cannot import name 'PyJWT' from 'jwt': you have a shadowing file or ancient version; different fix.
• jwt.exceptions.ExpiredSignatureError or decode errors: the import works, your token or call is wrong.
• python-jose users: that package imports as jose, not jwt.

Tool and version compatibility

PyJWT 2.x, Python 3.7+. PyJWT 1.x is ancient; upgrade.

Why it happens

PyPI name and import name differ: pip install PyJWT gives you import jwt. There is also a squatter package literally named jwt that does nothing useful. Installing the wrong one, or installing into a different interpreter than the one running the code, produces exactly this error.

Edge cases

• A file named jwt.py in your project shadows the package; rename it.
• If both jwt and PyJWT show in pip list, uninstall jwt.
• In Docker, make sure the pip install happens in the same layer/stage that runs the app.

The question of why No module named 'jwt' appears on startup even though JWT auth was configured is documented in real project troubleshooting guides. The verified fix: the import is jwt but the pip package is PyJWT, so pip install PyJWT (using python -m pip to match the interpreter).
