bug/<short-name> ImportError: cannot import name 'PSSyntaxError' from 'pdfminer.pdfparser'

[dp-0809]

Describe the bug
pip install unstructured[all-docs]==0.11.8

Error:
Traceback (most recent call last):
from unstructured.partition.pdf import partition_pdf
from unstructured.partition.pdf_image.pdfminer_processing import (
from pdfminer.pdfparser import PSSyntaxError

currently using：
unstructured 0.11.8 pypi_0 pypi
unstructured-client 0.8.1 pypi_0 pypi
unstructured-inference 0.7.18 pypi_0 pypi
unstructured-pytesseract 0.3.13 pypi_0 pypi

I have searched the issue board, but the unstructured patch is different.
pdfminer.six 20250506 ->pdfminer.six==20240706
cause dependency error:
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
pdfplumber 0.11.7 requires pdfminer.six==20250506, but you have pdfminer-six 20240706 which is incompatible.

How can i solve this problem?
update unstructured to which patch?

I reinstall unstructured[all-docs]==0.17.2 seems ok

Not sure if anyone else has run into this issue like me as well. I was able to fix this by going to the pdfminer_utils.py within the unstructured library.

The file in particular was here for me:

{directory where your virt env is}/.venv/lib/python3.11/site-packages/unstructured/partition/pdf_image/pdfminer_utils.py

making an adjustment to the import on line 9:

Old import:

from pdfminer.pdfparser import PSSyntaxError

New import:

from pdfminer.pdfparser import PDFSyntaxError as PSSyntaxError

This fixed all my issues.
