This error suggests that there is a mismatch between GDAL and the system libraries, usually stemming from a version conflict or misconfiguration.

Step-by-step Solution

Here’s how to tackle the import problem effectively:

1. Identify the Problem with GDAL

The first step is understanding that the error you are encountering is likely linked to how GDAL is installed or configured on your system. This is particularly true when using Django applications that require geospatial features.

2. Linking GDAL Correctly

To resolve the GDAL import issue, you can run the following command in your terminal:

This command utilizes Homebrew (a package manager for macOS) to ensure that GDAL is properly linked in your system. This step is crucial, as it can rectify any misconfiguration related to your GDAL installation.

3. Downgrade Django (If Necessary)

If you are still experiencing issues even after correcting the GDAL linkage, the next step is to consider the version of Django you are using. In your case, Django 4.1.1 might not be compatible with your current setup.

Downgrade to a stable version that's known to work well with Tastypie, such as 3.2. You can do this using pip:

After making these changes, it’s a good idea to verify your environment:

Ensure that you are in the correct virtual environment where your project dependencies are installed.

Check if other dependencies are affecting your Django or GDAL installation.

5. Test Your Application

Finally, restart your Django application:

By carefully addressing the GDAL configuration and aligning your Django version with supported packages, you can easily resolve the import issue with ModelResource in Tastypie.

Now that you've solved this problem, you can confidently continue building your API. Happy coding!
