Hello, Trying to run a single line: (Python 2.7.15 under Pycharm)

Windows-10-10.0.17763 ('Python', '2.7.15 (v2.7.15:ca079a3ea3, Apr 30 2018, 16:22:17) [MSC v.1500 32 bit (Intel)]') ('NumPy', '1.16.1') ('OpenCV', '4.0.0') ('Camelot', '0.7.2')

Ghostscript 64 installed under Win10 64 bit:

C:\Users\Rafi>gswin64c.exe -version GPL Ghostscript 9.26 (2018-11-20) Copyright (C) 2018 Artifex Software, Inc. All rights reserved.

There is a path to C:\Program Files\gs\gs9.26\bin and to C:\Program Files\gs\gs9.26\bin.

Tracking the source of the Python exception, it seems that the code in __win32_finddll(): fails to find the Registry key.

Using Regedit, there is a key: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\GPL Ghostscript\9.26 with two entries GS_DLL: C:\Program Files\gs\gs9.26\bin\gsdll64.dll and GS_LIB - C:\Program Files\gs\gs9.26\bin;C:\Program Files\gs\gs9.26\lib;C:\Program Files\gs\gs9.26\fonts

The statement QueryInfoKey(k1) returns (in _gsprint.py) (0, 0, 131955508546095202L), thus range(0,0) is [] and the loop fails, so the function returns None.

Any suggestions? Thanks, --Rafi

[vinayak-mehta]

Did you try the solutions mentioned in #184?

[rafiepstein]

Hello Vinayak, I am not sure what you mean by "solution mentioned"... As far as I could tell, no solution relevant to Windows environment is mentioned. Ghoscript is installed as per the test suggested. PATH is setup correctly. The problem seems to be in _gsprint.py, line: for num in range(0, QueryInfoKey(k1)[0]): as QueryInfoKey(k1) (0, 0, 131955739057984515L) thus range(0, QueryInfoKey(k1)[0]) is empty, and it doesn not find the dll.

Any suggestions?

[tal-yifat]

I'm having a similar issue, and couldn't solve it using the solutions mentioned in #184. I'd appreciate any suggestions.

I'm using the foo.pdf from the documentation.

tables = camelot.read_pdf('foo.pdf')

And getting the error message:

I have the same issue with the standalone version of Ghostscript (install version is not allowed due to the IT policy in my company). I had set the bin and lib directories of the Ghostscript (standalone) in PATH but Camelot is still trying to find the Ghostscript from the Windows registry.

[pantuts]

In macos brew install ghostscript

[tal-yifat]

In my case, Ghostscript is successfully installed. Shouldn't this be a bug?

[KAIXIE]

Ghostscript is successfully installed. Shouldn't this be a bug? yes it is a bug!!!!!

[vinayak-mehta]

I'll look into this over the weekend.

[wangxiangtao]

exact same issue as well. I have the same issue with the standalone version of Ghostscript (install version is not allowed due to the IT policy in my company). I had set the bin and lib directories of the Ghostscript (standalone) in PATH but Camelot is still trying to find the Ghostscript from the Windows registry.

[vinayak-mehta]

I currently don't have a Windows machine to reproduce this, let me install it on my current laptop. I believe we should just try to get rid of ghostscript with #96.

[GuillaumeDesforges]

Same issue here

[marcoloew333]

Same for me. Even if i install ghostscript and python3-ghostscript via pip. macOS with PyCharm. Both latest versions.

[daudna]

Had the same Issue on Windows. I just installed Ghostscript installer from this Website: https://www.ghostscript.com/download/gsdnld.html My Code is now having no issues.

[ghost]

Had the same Issue on Windows. I just installed Ghostscript installer from this Website: https://www.ghostscript.com/download/gsdnld.html My Code is now having no issues.

My code is now having no issues, too, thank you

[cwhan-yonsei]

I have the same issue. Although I've tried other install method to install ghost script, it still does not work...

macOS - brew install ghostscript - still get this error

[lswh]

Hi this error also exists for me.

[lswh]

I was investigating this code earlier and I noticed for my macOS implementation that it's having some issue with the conditional of libgs.so file which produces the runtime error. I tried working on both virtualenv and conda but I also suspect that the find_library cdll is not working in it somewhere. It does not detect the GhostScript even when I installed from source and did a make so compiled install because that file extension for MacOS is a different one from shared object on Linux. I presume this bug does not happen on Ubuntu/Linux and can only be observed in Windows and MacOS. I will try on a Linux machine and see if I am able to detect the same bug.

[nachiket8188]

Had the same Issue on Windows. I just installed Ghostscript installer from this Website: https://www.ghostscript.com/download/gsdnld.html My Code is now having no issues.

My code is now having no issues, too, thank you

This did the trick for me too.

[kavinsingh1]

Had the same Issue on Windows. I just installed Ghostscript installer from this Website: https://www.ghostscript.com/download/gsdnld.html My Code is now having no issues.

I also tried, its working perfectly fine..just after installation

[shivaniarbat]

Had the same Issue on Windows. I just installed Ghostscript installer from this Website: https://www.ghostscript.com/download/gsdnld.html My Code is now having no issues.

This worked for me too.

[forum2k9]

Yes, on windows 10 it works after installing the ghostscript exe at: https://www.ghostscript.com/download/gsdnld.html

[sourabhsinha396]

I had had this issue on aws elasticbeanstalk in a django app while reading a pdf : I just needed to add these lines packages: yum: ghostscript: [] in the django.configure file

[iicedream]

Had the same Issue on Windows. I just installed Ghostscript installer from this Website: https://www.ghostscript.com/download/gsdnld.html My Code is now having no issues. I solved this problom by this url https://www.ghostscript.com/download/gsdnld.html

[slamer59]

Some hack:

Looking at sources: https://github.com/atlanhq/camelot/blob/9137df2f6c6acb2fdaef9256ac42bf11f6afd99e/camelot/ext/ghostscript/_gsprint.py#L223

My guess is that downloading : https://www.ghostscript.com/download/gsdnld.html install some HKEY_LOCAL_MACHINE aka GS_DLL which solved the problem.

For ones who cannot add HKEY_LOCAL_MACHINE, add it to HKEY_CURRENT_USER\Software\key_name\GS_DLL\GS_DLL GS_DLL is a REG_SZ containing dll path.

Choose key_name in "AFPL Ghostscript", "Aladdin Ghostscript", "GNU Ghostscript", "GPL Ghostscript",

Also import HKEY_CURRENT_USER here https://github.com/atlanhq/camelot/blob/9137df2f6c6acb2fdaef9256ac42bf11f6afd99e/camelot/ext/ghostscript/_gsprint.py#L192

and here:

MacOS, had the same error after running brew install ghostscript

Running brew link --overwrite ghostscript solved it.

[goutam-ghosh]

"errorMessage": "Please make sure that Ghostscript is installed", "errorType": "RuntimeError"

getting this error while run the code using lambda function aws. Already camelot and ghostscript added as a dependency. I need to resolve as soon as possible. Please help.

my code is : import camelot

def pdfToJson(event=None,context=None): tables = camelot.read_pdf("./week-1-2019-20.pdf") tables[0].df.to_json("./sample.json")

Note:Locally it is working properly.

#serverless #awslambda #python #camelot #ghostscript

[goutam-ghosh]

And more thing how to add ghostscript dependencies for lambda function python?

[AJoR43]

MacOS, had the same error after running brew install ghostscript

Running brew link --overwrite ghostscript solved it.

That also solved it for me (MacOS).

[zeboventura]

I tried all the solutions in this thread, conda, brew etc... Still doesn't work! I am on MacOS HighSierra version 10.13.6. Python 3.7.4
