The sip module implements API v11.0 to v11.2 but the PyQt5.QtCore module requires API v11.3

问题

I have a problem with this error. For the record, I'm using PyQt4. Thanks for any help!

回答1:

I solved this issue by uninstalling and reinstalling sip using pip.

pip uninstall sip
pip install sip

Just doing the upgrade might have work as well, but I got an error during it because the file was in use.

Doing the equivalent in Anaconda might solve the issue.

I got the same error with pycharm and pyqt4 ... for me was the solution:

The python version (in my case python 3.4) and the pyqt4 version have to match... So I insalled python-3.4.4.msi and after this PyQt4-4.11.4-gpl-Py3.4-Qt4.8.-x32.exe

Now it works
