Hi all, I'm new to the list and new to Python also. I've been requested to create a program with a webview in it. I've tried to import QtWebKit module but I have this error:
Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: dlopen(/Library/Python/2.6/site-packages/PyQt4/QtWebKit.so, 2): Symbol not found: _kCFWebServicesProviderDefaultDisplayNameKey
Referenced from: /Library/Frameworks/QtWebKit.framework/Versions/4/QtWebKit Expected in: /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation
It's the only one module that returns me this error. All other installed modules are ok. The file /Library/Python/2.6/site-packages/PyQt4/QtWebKit.so exists.
What could the problem be?
This is probably caused by a copy of QtWebKit that was build on a later version of the OS than you're currently using (for example building QtWebKit on OSX 10.6 and running on OSX 10.5). The symbol that's mentioned is not a public symbol in CoreFoundation in OSX 10.6 or 10.7 (I haven't checked older SDKs), it could therefore also be a copy of QtWebKit build on an older version of the OS that is accessing a private symbol that got removed in a later release.
I get the same error. PyQt4 used to work until a few days ago. Then I decided to install the new libraries from QT (qt-mac-opensource-4.8.0-rc1.dmg) and at the same time reinstalled PyQt (PyQt-mac-gpl-4.8.6.tar.gz) and SIP (sip-4.13.tar.gz). Since then I get the exactly same error. Maybe qt 4.8 was built for Lion, while I am still on Snow Leopard?
Hi Christian, I did exactly what you did as I had some problems with the previous installation. I don't know if Qt4.8 is for Lion, I just followed instructions to install all for "Mac OSX", there was nothing that made me think that it was for Lion only. I spent a lot of time to uninstall and reinstall all to make it work (except for QtWebKit unfortunately) and I don't want to redo it again. Could there be another solution maybe?
