Hey, tried reproducing your started code for extracting text import pdfbox pi = pdfbox.PDFBox() text = pi.extract_text('./reports/sample.pdf') I'm running python 3.7 Got this error

What version of Python are you using? What version of sarge is installed on your system?

[pHequals7]

Python : 3.7 sarge : 0.1.5

[lebedov]

I assume you meant Python 3.7.0 and sarge 0.1.5 rather than sarge 0.1.5.post0. If so, I can't reproduce the problem with those package versions installed on Linux.

In any case, the exception is being raised in sarge, not python-pdfbox. Can you try running the following code with Python and see if it executes successfully?

import sarge
p = sarge.capture_stdout('hostname')
print(p.stdout.text)

[lebedov]

Also was not able to reproduce the error on Windows 10; the unit tests pass.

[pHequals7]

Hey sorry for the mixup, my sarge version is in fact 0.1.5.post0. And I tried running the sarge code, and the same 'local variable 'p'....' error props up!

So since sarge is causing the problems, any way to overcome this??

[lebedov]

Try asking the sarge developer by submitting an issue: https://bitbucket.org/vinay.sajip/sarge

Very likely application PDFBox try to run don't have executable bit set. We've got the same error from sarge in similar situation.

[lebedov]

FYI, python-pdfbox doesn't use sarge anymore, so this bug should be moot.
