'Version' object has no attribute 'major' in macOS 11

[somyost-ginkgo]

I got issue 'Version' object has no attribute 'major'

My environment have python 3.7 java 15.0.2

[lebedov]

I can't reproduce this with Python 3.7.10 on MacOS 10.15.7. Can you try adding the line

print(p.result)

right before the line

versions = list(filter(lambda v: pkg_resources.parse_version(v).major<3,
                                  p.result))

in ~/opt/anaconda3/lib/python3.7/site-packages/pdfbox/__init__.py ensure that ~/Library/Caches/python-pdfbox does not exist, and try running

import pdfbox
p = pdfbox.PDFBox()

again and post what you observe?

I actually have the same error on macOS: 10.15.7 python: 3.8.1 java: openjdk version "1.8.0_222"

I'm not using anaconda in this case.

Running print(p.result) gives the following output

['1.1.0', '1.2.0', '1.2.1', '1.3.1', '1.4.0', '1.5.0', '1.6.0', '1.7.0', '1.7.1', '1.8.0', '1.8.1', '1.8.10', '1.8.11', '1.8.12', '1.8.13', '1.8.14', '1.8.15', '1.8.16', '1.8.2', '1.8.3', '1.8.4', '1.8.5', '1.8.6', '1.8.7', '1.8.8', '1.8.9', '2.0.0-RC1', '2.0.0-RC2', '2.0.0-RC3', '2.0.0', '2.0.1', '2.0.10', '2.0.11', '2.0.12', '2.0.13', '2.0.14', '2.0.15', '2.0.16', '2.0.17', '2.0.18', '2.0.19', '2.0.2', '2.0.20', '2.0.21', '2.0.22', '2.0.23', '2.0.3', '2.0.4', '2.0.5', '2.0.6', '2.0.7', '2.0.8', '2.0.9', '3.0.0-RC1']

Running

import pdfbox
p = pdfbox.PDFBox()

Gives me the same error.

@kontrol Strange - I can't replicate the error with Python 3.8.2 from conda-forge. It seems that the Version class returned by pkg_resources.parse_version() in the Python 3.8.2 that comes with MacOS doesn't have the same attributes as the one in conda-forge:

MacOS:

Same AttributeError: 'Version' object has no attribute 'major' here on Ubuntu 20.04:
