See here -> Unable to install PyQt5 on Raspberry Pi

You have the same problem even if your not using a Raspberry Pi.

The version of pyqt-tools you're trying to install is using PyQt5==5.14.0 In the pyproject.toml file for PyQt5, sip >=5.0.1 <6 is not a valid PEP518 format. It should be sip >=5.0.1, <6

In PyQt5==5.14.1 this error was fixed. Thus, you'll need to use a version of pyqt-tools that depends on PyQt5 >= 5.14.1
