bzr info crashes on MacOS X 10.9. ERROR: exceptions.ImportError

[Alex Mitchell]

Running "bzr info" crashes after upgrading to MacOS X 10.9. I reinstalled bzr, and also installed XCode command line tools (as suggested here https://bugs.launchpad.net/bzr-mac-installers/+bug/1061330 for the same bug on 10.8), but no luck. It seems that subversion was still not installed after installing the command line tools. Any ideas how to get the appropriate extensions installed?

[Daniel Conde (dpfconde)]

The problem is, Mavericks command line tools libraries are set on /Library/Developer/CommandLineTools/usr/lib/ instead of /usr/lib. This causes bazaar to fail the load of the needed svn libraries because they are not available in /usr/lib.

The fix for this is to just link the necessary libraries from /Library/Developer/CommandLineTools/usr/lib to /usr/lib like this:
sudo ln -s /Library/Developer/CommandLineTools/usr/lib/libsvn_client-1.0.dylib /usr/lib/libsvn_client-1.0.dylib
sudo ln -s /Library/Developer/CommandLineTools/usr/lib/libsvn_subr-1.0.dylib /usr/lib/libsvn_subr-1.0.dylib

Once you've linked those libraries into /usr/lib, do bzr svn operations work correctly? I've been told by the author of bzr-svn that it is only compatible with svn 1.6 but OS X Mavericks has svn 1.7 installed.

[Alex Mitchell (alexm-nus)]

That seems to work, thanks! At least it solves the specific problem I reported above related to "bzr info". I haven't tried any bzr svn operations.

[Moisés López - http://www.vauxoo.com (moylop260)]

This work for me.
Thanks you

I executed
ln -s /Library/Developer/CommandLineTools/usr/lib/*.dylib /usr/lib/

[Chamod (chamod)]

Thanks. I'm running Xcode 6.1 on Yosemite, so I had to make a small change.

sudo ln -s /Applications/Xcode.app/Contents/Developer/usr/lib/* /usr/lib

[Andrew Johnson (anj)]

This workaround doesn't work for me on El Capitan, I get "Operation not permitted" errors from ln due to Apple's System Integrity Protection. I tried putting the soft links into /usr/local/lib, no joy, nor do they work in the /Library/Python/2.6/site-packages/subvertpy/ directory (where the client.so library that is trying to link to them is placed). It's a real pain to have to disable SIP just to do this, and I'm guessing that our sysadmins wouldn't be too happy about it.

[Tom Dickson (8-launchpad-bombcar-com)]

This happens on Mac OS X Sierra also (workaround by Chamod works if you disable SIP):
