ModuleNotFoundError: No module named 'keycloak'

ModuleNotFoundError: No module named 'keycloak'

TL;DR: the distribution is called python-keycloak, not keycloak. Run pip install python-keycloak and the import works.

ModuleNotFoundError: No module named 'keycloak'

The fix

pip install python-keycloak

Verify:

python -c "from keycloak import KeycloakOpenID; print('ok')"

Expected output: ok.

When this applies

• First-time Keycloak integration in Python.
• Fresh virtualenvs, containers, or CI runners.
• You ran pip install keycloak and the import still failed.

When it does NOT apply

• Connection errors to the Keycloak server, which happen after the import works.
• keycloak.exceptions errors, which are runtime API errors, not import errors.

Why this happens

The keycloak name on PyPI does not belong to this project, so the distribution took the python- prefixed name while the module kept the clean one. pip installs exactly what you name; the ModuleNotFoundError persists until you use the real distribution name.

Compatibility

python-keycloak 3.x/4.x/5.x. Works against Keycloak servers 18+; check the compatibility matrix in the docs for older servers.

The module is keycloak but the distribution is python-keycloak, so pip install keycloak does not provide the expected API. The python-keycloak project page documents pip install python-keycloak as the install command. This is the same naming trap as python-jose and python-gnupg, and it bites everyone integrating Keycloak auth into Python for the first time.
