<p class="MsoNormal">Good morning,<o:p></o:p></p>

<p class="MsoNormal">I have Qt5 5.15.5_1 installed with homebrew on my Mac M1 laptop running macOS Monterey. I’m not able to install PyQt5 using pip in a virtualenv (using the system’s Python 3.8.9). It appears to hang, then after 1-2 hours is killed by the
OS. A verbose run shows it stuck querying for input to accept the GPL license: “This is the GPL version of PyQt 5.15.7 (licensed under the GNU General Public License) for Python 3.8.9 on darwin.”, followed by the input options, but it doesn’t appear to accept
the keyboard input. Is there a way to get past this?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I also tried building PyQt 5.15.7 from source as described in [1]. I first installed `pyqt-builder` 1.13.0. Then the `sip-install` approach failed during build without enough info, so running `make` separately (from the `build` directory)
then fails apparently trying to link with libpython3.8:<o:p></o:p></p>
