FYI     PyQt is now available on all platforms via conda    Use conda install pyqt to get these  Python bindings for the Qt framework    1 02 PM -   1 May 2014   https   twitter com ContinuumIO status 461958764451880960

It looks like the latest version of anaconda forces install of pyqt5 6 over any pyqt build  which will be fatal for your applications  In a terminal  Try   conda install -c anaconda pyqt 4 11 4   It will prompt to downgrade conda client  After that  it should be good   UPDATE   If you want to know what pyqt versions are available for install  try   conda search pyqt   UPDATE  The most recent version of conda installs anaconda-navigator  This depends on qt5  and should first be removed   conda uninstall anaconda-navigator   Then install  newest  qt4   conda install qt 4

Updated version of  Alaaedeen s answer  You can specify any part of the version of any package you want to install  This may cause other package versions to change  For example  if you don t care about which specific version of PyQt4 you want  do   conda install pyqt 4   This would install the latest minor version and release of PyQt 4  You can specify any portion of the version that you want  not just the major number  So  for example  conda install pyqt 4 11   would install the latest  or last  release of version 4 11   Keep in mind that installing a different version of a package may cause the other packages that depend on it to be rolled forward or back to where they support the version you want
