Hello, I have a similar problem.
pip3 install PyQt5 Requirement already satisfied (use --upgrade to upgrade): PyQt5 in /usr/local/lib/python3.5/dist-packages Requirement already satisfied (use --upgrade to upgrade): sip<4.20,>=4.19 in /usr/local/lib/python3.5/dist-packages (from PyQt5) You are using pip version 8.1.2, however version 9.0.1 is available. You should consider upgrading via the 'pip install --upgrade pip' command. I ran the command pip install --upgrade pip yet, but it's still the same problem. -- You received this message because you are subscribed to the Google Groups "mnemosyne-proj-users" group.
