    raise ClassNotFound('no lexer for filename %r found' % fn)
pygments.util.ClassNotFound: no lexer for filename '.flake8' found

ASSISTANT: It seems that the `guess_lexer_for_filename` function from Pygments is raising a `ClassNotFound` exception because it cannot find a lexer for the '.flake8' file. To fix this issue, you can add a try-except block around the `guess_lexer_for_filename` function call to handle the exception and continue processing other files.

Here's the change you need to make in the `aider/getinput.py` file:

```python
aider/getinput.py
<<<<<<< ORIGINAL
            lexer = guess_lexer_for_filename(fname, content)
=======
            try:
                lexer = guess_lexer_for_filename(fname, content)
            except ClassNotFound:
                continue
>>>>>>> UPDATED
```

This change will catch the `ClassNotFound` exception and continue processing the remaining files without raising an error.
