Hi, when I run ./manage.py document_consumer this come out (OS X El Capitan)
Traceback (most recent call last): File "./manage.py", line 18, in <module> execute_from_command_line(sys.argv) File "/Users/Francesco/Library/Python/3.5/lib/python/site-packages/django/core/management/__init__.py", line 350, in execute_from_command_line utility.execute() File "/Users/Francesco/Library/Python/3.5/lib/python/site-packages/django/core/management/__init__.py", line 342, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Users/Francesco/Library/Python/3.5/lib/python/site-packages/django/core/management/base.py", line 348, in run_from_argv self.execute(*args, **cmd_options) File "/Users/Francesco/Library/Python/3.5/lib/python/site-packages/django/core/management/base.py", line 399, in execute output = self.handle(*args, **options) File "/Users/Francesco/Desktop/paperless-master/src/documents/management/commands/document_consumer.py", line 49, in handle self.loop() File "/Users/Francesco/Desktop/paperless-master/src/documents/management/commands/document_consumer.py", line 59, in loop self.file_consumer.consume() File "/Users/Francesco/Desktop/paperless-master/src/documents/consumer.py", line 116, in consume pngs = self._get_greyscale(tempdir, doc) File "/Users/Francesco/Desktop/paperless-master/src/documents/consumer.py", line 139, in _get_greyscale "-type", "grayscale", doc, png File "/usr/local/Cellar/python3/3.5.1/Frameworks/Python.framework/Versions/3.5/lib/python3.5/subprocess.py", line 950, in __init__ restore_signals, start_new_session) File "/usr/local/Cellar/python3/3.5.1/Frameworks/Python.framework/Versions/3.5/lib/python3.5/subprocess.py", line 1544, in _execute_child raise child_exception_type(errno_num, err_msg) FileNotFoundError: [Errno 2] No such file or directory: '/usr/bin/convert'

I've installed pip3 requirements from requirements.txt.

As stated in the requirements, you have to install ImageMagick which contains the missing convert binary.

Other users under OS X also had to install ghostscript to make things work, see here and issue #25.

If after installing these dependencies you still get the error message above, you might have to adapt the CONVERT_BINARY variable in settings.py to possibly /usr/local/bin/convert.

[Adrenocortico]

I've installed also ImageMagick and ghostscript but it continues not to work.

[pitkley]

If you open your Terminal and enter which convert, do you get a path to a binary returned? If so, be sure to use that path and set it in your settings.py as mentioned above!

[Adrenocortico]

Ok! Using /usr/local/bin/convert in CONVERT_BINARY it works! Thank you so much!

[pitkley]

No problem, glad I could help!

[pitkley]

@danielquinn Should we maybe do something like this and rely on the binary being on the path by default?

I had a similar thought when I saw this issue come up, but I think it might be best to just set settings.CONVERT_BINARY = os.environ("PAPERLESS_CONVERT", "convert"). That way the user can change the value in settings.py explicitly or set it with an environment variable in a wrapper or something. The default will always just look for convert in $PATH. It also means that what you see in settings.py is what you get, rather than having consumer.py make that decision. Does that sound cool with you?

[pitkley]

Yes, good thinking.

On the topic of naming the environment variable, should we try to name them like the variables, only prefixed with PAPERLESS_? Right now we have:

settings.py	Environment variable
OCR_THREADS	PAPERLESS_OCR_THREADS
FORGIVING_OCR	none
CONVERT_BINARY	PAPERLESS_CONVERT
SCRATCH_DIR	none
CONSUMPTION_DIR	PAPERLESS_CONSUME
MAIL_CONSUMPTION	PAPERLESS_CONSUME_MAIL_*
PASSPHRASE	PAPERLESS_PASSPHRASE
UPLOAD_SHARED_SECRET	PAPERLESS_SECRET

Maybe renaming one or the other to make them match might be worth thinking about and possibly adding missing ones.

[danielquinn]

There you go again, being all rational :-P

This is an excellent point. I'll create an issue and point it to this comment and will get to it soon.

[pitkley]

Sorry ;)
