To resolve the "ModuleNotFoundError: No module named 'MySQLdb'" error in
Superset version 4.1.2 with Python 3.10, you need to install the `mysqlclient`
package. This is necessary because, starting from Superset version 4.1.0,
database drivers like MySQL are not included in the base Docker image, so you
must manually add them.
Here are the steps to fix this:
1. **Install the MySQL client package**:
Run the following command to install the necessary Python package for
MySQL:
```bash
pip install mysqlclient
```
2. **For Docker deployment**:
If you are using Docker, create a custom Dockerfile to include necessary
system dependencies and the `mysqlclient` package. Add the following to your
Dockerfile:
```Dockerfile
FROM apache/superset:4.1.2
USER root
RUN apt-get update && apt-get install -y \
python3-dev \
default-libmysqlclient-dev \
build-essential \
pkg-config
RUN pip install mysqlclient
USER superset
```
Then, build and run your custom Docker image.
3. **For Kubernetes deployment**:
Modify your `values.yaml` file to include the following bootstrap script:
```yaml
bootstrapScript: |
#!/bin/bash
# Install system-level dependencies
apt-get update && apt-get install -y \
python3-dev \
default-libmysqlclient-dev \
build-essential \
pkg-config
# Install required Python packages
pip install mysqlclient
# Create bootstrap file if it doesn't exist
if [ ! -f ~/bootstrap ]; then
echo "Running Superset with uid {{ .Values.runAsUser }}" > ~/bootstrap
fi
```
These steps should resolve the module error and add MySQL support in
