Description of problem: matej@wycliff: ~$ pydoc -k wraps Traceback (most recent call last): File "/usr/bin/pydoc", line 5, in <module> pydoc.cli() File "/usr/lib64/python2.7/pydoc.py", line 2292, in cli apropos(val) File "/usr/lib64/python2.7/pydoc.py", line 1992, in apropos ModuleScanner().run(callback, key, onerror=onerror) File "/usr/lib64/python2.7/pydoc.py", line 1973, in run module = loader.load_module(modname) AttributeError: 'NoneType' object has no attribute 'load_module' Version-Release number of selected component (if applicable): python-libs-2.7.5-8.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.see above 2. 3. Actual results: Expected results: Additional info:
The problem: - This only happens when PyQt4 is installed. - On line 1962, loader is instantiated by importer.find_module. For "PyQt4.uic.pyuic", importer.find_module returns None, which then causes the AttributeError. - File /usr/lib64/python2.7/site-packages/PyQt4/uic/pyuic.py is a symlink to /usr/bin/pyuic4, which lives in PyQt4-devel. - If PyQt4-devel is not installed, pyuic.py is unimportable, which makes pydoc fail. IMO this is a problem in packaging of PyQt4, since pyuic.py file should be in PyQt4-devel package, not in the main PyQt4 package where it's unusable. I'll open a bug for PyQt4.
Fixed in PyQt4 => moving to MODIFIED.
Root cause has been solved by bz#1026209. Now, traceback doesn't occur if PyQt4-devel is not installed: # rpm -qa | grep PyQt4 PyQt4-dbus-4.10.1-12.el7.noarch PyQt4-4.10.1-12.el7.x86_64 # pydoc -k wraps ldap.functions - functions.py - wraps functions of module _ldap ldap.ldapobject - ldapobject.py - wraps class _ldap.LDAPObject #
