    from .utils import IgnorantTemporaryDirectory
ImportError: attempted relative import with no known parent package

ASSISTANT: The error message indicates that Python is unable to find the `utils` module when it's being imported in `test_repomap.py`. This is because the import statement is using a relative import with the dot (`.`) prefix, which is not working in this context.

To fix this, we need to change the relative import to an absolute import. This means we need to specify the full path to the `utils` module from the project's root directory.

Here is the change you need to make:

```python
tests/test_repomap.py
<<<<<<< ORIGINAL
from .utils import IgnorantTemporaryDirectory
=======
from tests.utils import IgnorantTemporaryDirectory
>>>>>>> UPDATED
```

This change tells Python to import the `IgnorantTemporaryDirectory` class from the `utils` module located in the `tests` directory, which is an absolute path from the project's root directory.
