WeasyPrint fails with error on OSX 10.7.5/homebrew #79

BrianHicks · 2013-04-26T17:31:26Z

I've got the following versions of the requirements installed:

$ brew install python cairo pango gdk-pixbuf libxml2 libxslt libffi
Warning: python-2.7.4 already installed
Warning: cairo-1.12.14 already installed

Warning: libxml2-2.9.0 already installed
Warning: libxslt-1.1.28 already installed
Warning: libffi-3.0.13 already installed

And when I install using mktmpenv --system-site-packages -i WeasyPrint, I get this output.

When I run WeasyPrint, I get the following:

It looks like the install was successful, it’s only at runtime that dlopen() can not load dynamic libraries. Do you know what’s the full path of any .so or .dylib file installed by the cairo homebrew package? What are the values of the LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, and DYLD_FALLBACK_LIBRARY_PATH environment variables?

SimonSapin · 2013-04-26T23:35:13Z

Also, are you using the Python installed by Homebrew?

BrianHicks · 2013-04-26T23:46:47Z

While I was getting the answers to those, I noticed the libcairo formula became keg-only, so it wasn't loaded into /usr/local/lib. Running brew link --force cairo fixed it for me.

SimonSapin · 2013-04-27T00:06:07Z

I … am not sure what that means. Do you have suggestions for Homebrew instructions I could put in the documentation?

BrianHicks · 2013-04-27T00:13:57Z

That means they figured it's on OSX by default so they shouldn't link it implicitly. There generally aren't too severe consequences for linking, but it's definitely something that varies on a case-by-case basis. Maybe just mention that it might be the case that it needs to be manually linked? That way people won't keep opening dumb bugs like this one. ;)

SimonSapin · 2013-04-27T00:16:03Z

Ideally I’d like a set of instructions in the docs that people can follow even if they don’t care about pythons and virtualenvs and shared libraries. I’m trying to figure out what that is on OS X, but I don’t have a Mac to test on :/

BrianHicks · 2013-04-27T00:18:12Z

A good goal to have! Unfortunately I'm not much help. I don't know enough about cairo and the programs which use it to be of any real assistance. Sorry. I'm willing to help test instructions though, should you need a hand.

pelegrini · 2013-04-30T23:36:24Z

Hi, @BrianHicks, I'm having the same problem but I am not using homebrew.

I'm using macports and installed like this:

Do you have an idea what should I do?

BrianHicks · 2013-05-01T03:57:55Z

I haven't used port in a long time. Find out where they put libs and add it
to your path maybe? It's probably /usr/local/lib?

Hi @pelegrini . I can’t seem to find the github issue again, but another Macports user had the same problem and resolved it by making sure to use the Python installed by Macports. Apparently it’s common on OS X to have Python install from multiple sources.

pelegrini · 2013-05-02T10:09:57Z

@BrianHicks, the location was /opt/local, but the $PATH was right.

@SimonSapin, it's a good idea, but I did not want to install another python26 in my machine...

What I did was uninstall macports completely and install homebrew. Although the problem persisted, brew link --force cairo worked for me.

Thanks very much for your help, guys.

SimonSapin · 2013-05-02T10:16:41Z

So … suggestions for the install docs?

@pelegrini , I don’t think that the PATH env variable is relevant to shared library loading. LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, and DYLD_FALLBACK_LIBRARY_PATH are.

rogerhil · 2013-09-18T02:43:41Z

It worked for me setting the correct path for DYLD_LIBRARY_PATH.

DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/usr/local/Cellar/cairo/1.10.2/lib/

ghost · 2013-09-21T18:54:56Z

Hi, I have just got the same issue on Mac 10.8.4.
Investigated an issue and localization gave me, that:

$ brew install cairo

- returned HTTP 404 error for glib dependency
So, I just made:

$ brew update

After that both installation of cairo and running weasyprint were fine:

$ brew install cairo pango gdk-pixbuf libxml2 libxslt libffi
$ pip install WeasyPrint
$ weasyprint --help

- worked for me

jmelett · 2013-11-19T21:02:01Z

$ export DYLD_FALLBACK_LIBRARY_PATH=/opt/local/lib

Fixes the issue with macports.

chrisbrownnwyc · 2014-10-21T20:30:13Z

@jmelett thanks! This solved the issue for me and I'm still using the system python. (for many reasons I prefer to use it). I set the path and then reinstalled cairocffi with

 pip install --upgrade --force-reinstall cairoffi

bzamecnik · 2015-01-11T13:29:10Z

#79 (comment)

I can confirm that DYLD_FALLBACK_LIBRARY_PATH solution works with Python 3.4 and macports.
I could be useful to put this export into ~/.profile.

derekjanni · 2019-09-11T22:37:12Z

Just wanted to comment that I found this problem with Python 3.6 + MacOS High Sierra. Installed deps with brew as instructed but got similar complaints. Fixed via export DYLD_FALLBACK_LIBRARY_PATH=$DYLD_FALLBACK_LIBRARY_PATH:/usr/local/lib
