dependecy problem reportlab - allthough installed...

# apt-get install python-reportlab

.. already installed.

Debian 6 squeeze

[andreasotto]

# python -c 'import reportlab' && echo "installed"
installed

[andreasotto]

Ah, i've seen OCRmyPDF wants to have reportlab version >= 3.0
Under Debian 6 squeeze the version is: 2.4-4
Are there real dependencies for >= 3.0?

[jbarlow83]

OCRmyPDF v3.0-rc2 needs reportlab >= 3.0 (although there is a workaround to avoid reportlab: --pdf-renderer tesseract if you have Tesseract 3.03). In both v2.0 and v3.0 of OCRmyPDF, it's a 'firm' dependency because older reportlabs had a serious bug in image handling that really bloated the sizes of PDFs.

[Wikinaut]

Actual problem with

• Opensuse Tumbleweed
• python-reportlab is installed
• OCRmyPDF still says "Please install the python library reportlab. Exiting...

Having the problem and reading this issue I checked the Tumbleweed reportlab version (2.7-3.3) and let me post the

suggestion

to change the OCRmyPDF dependency-checker test to "Please install the python library reportlab version >= 3.0". i.e. to notify the user they must install a correct version.

[Wikinaut]

@jbarlow83 pls. can you explain, where the option --pdf-renderer tesseract is to be added ? It does not work on a command line of OCRmyPDF, and it is not mentioned in the help, where such an option could be added.

[jbarlow83]

Only the new version (a pre-release) supports it:
https://github.com/fritz-hh/OCRmyPDF/releases version v3.0-rc2.

Or download the source latest from the "master" branch.

hmm, one problem is solved (when checking out here, the default branch is v2.x. i changed this now to master) ...

but now I get

# sh ./OCRmyPDF.sh -h
Traceback (most recent call last):
  File "/usr/lib64/python3.4/runpy.py", line 170, in _run_module_as_main
    "__main__", mod_spec)

  File "/usr/local/src/OCRmyPDF/ocrmypdf/main.py", line 16, in <module>
    import PyPDF2 as pypdf
ImportError: No module named 'PyPDF2'

When I run

./OCRmyPDF.sh -h
bash: ./OCRmyPDF.sh: Keine Berechtigung

It's a Python 3 package now. Run the installer in the current directory: pip3 install -e .

[Wikinaut]

oops, while you wrote your answer, I read the readme and did the pip3, but:

  FileNotFoundError: [Errno 2] No such file or directory: 'mutool'

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /usr/local/src/OCRmyPDF

So I have to install this, too. (should it be added to the dependency checks ???)

[Wikinaut]

uh, `mutool`` is not in Tumbleweed. Have to look for it. (Even Tesseract is easier to install)

[jbarlow83]

It's mupdf-tools. If it's a pain to get, how is qpdf? Both do the same thing.

You'll need tesseract, ghostscript, unpaper, poppler, and java too.

[Wikinaut]

It is part of mupdf in Opensuse

[Wikinaut]

Now this is gone, but I have

pip3 install -e .

(post above updated with the complete output)

[jbarlow83]

Added a possible fix - do a git pull.

[Wikinaut]

I was (I am) already on 6e6f918 . This gives the above error.

[jbarlow83]

Apologies, I pushed it to wrong repo. commit 6901550 should now be available on the main repo.

    OCRmyPDF requires 'mutool' 1.7a or higher.  Your system has
    'mutool' but we cannot tell what version is installed.  Contact the
    package maintainer.


    This program is REQUIRED for OCRmyPDF to work.  Installation will abort.


    On systems with the aptitude package manager (Debian, Ubuntu), try these
    commands:
        sudo apt-get update
        sudo apt-get install mupdf-tools

    On RPM-based systems (Red Hat, Fedora), search for instructions on
    installing the RPM for mupdf-tools.

mupdf 1.7-1.3 on Opensuse Tumbleweed

[jbarlow83]

I don't know what to think when Linux distributions make up arbitrary version numbers that don't follow the package's own conventions, as in this case.

I dropped the version requirement to mupdf 1.7.

You need to install as sudo or create a virtual environment with pyvenv and
install to that environment. As the error message says it doesn't have
permission to write /usr/local.

With a virtual environment:

pyvenv venv
source venv/bin/activate
pip3 install -e .
