GitHub user Ikarashi0310 created a discussion: ModuleNotFoundError: No module
named 'authlib' when implementing Google OAuth with Apache Superset Docker
I'm encountering a ModuleNotFoundError: No module named 'authlib' error while
hosting Apache Superset and attempting to implement Google authentication
(OAuth). I'm blocked by this persistent error and cannot proceed.
I have attempted to explicitly install authlib in my custom Dockerfile.
**Error Log**

**Dockerfile**
```
FROM apache/superset:latest
USER root
RUN apt update && apt install -y \
python3-dev \
default-libmysqlclient-dev \
build-essential \
pkg-config \
&& rm -rf /var/lib/apt/lists/*
RUN uv pip install --no-cache-dir mysqlclient pymysql gunicorn authlib==1.2.0
COPY superset_config.py /app/superset_home/superset_config.py
RUN chown superset:superset /app/superset_home/superset_config.py
USER superset
CMD ["gunicorn", "-w", "2", "--threads", "8", "-b", "0.0.0.0:8088",
"superset.app:create_app()"]
```
**Question**
Even though I explicitly run uv pip install ... authlib==1.2.0 as the root
user, the application is failing to import authlib when running as the superset
user, resulting in a ModuleNotFoundError.
Why is the authlib package not being found, and how can I correctly install
this dependency within the Superset image for OAuth to work?
**Potential Hint / Context**
I noticed in the official Superset documentation that dependencies are
sometimes suggested to be added to a docker/requirements-local.txt file and
rebuilt via docker-compose. However, I am trying to build a custom image using
a standalone Dockerfile.
Could the issue be related to:
The uv pip install command placing the package in a location not accessible or
recognized by the superset user/environment?
The apache/superset:latest base image using a Python virtual environment that
isn't being targeted by the uv pip install command?
Any guidance on the correct way to layer dependencies onto the apache/superset
base image to enable Google OAuth is greatly appreciated! 🙏
