Monitor install error

Hi All,

Doing a Monitor install and getting the following error after dependancies are built:

Any ideas?

Not sure about monitor. But MPF doesn’t run on python 3.9. I would try to downgrade to 3.8 and try again. It builds packages for 3.6 - 3.8. So probably can’t find a 3.9 package and thus can’t install.

F.Y.I with minor changes I managed to get mpf running on Python 3.10 (still took me a while to dig into the code).

3.10 is the default version shipped with my O.S (Archlinux) and I tried using pyenv (https://github.com/pyenv/pyenv) which allow multiple version of python at same time but I wasn't successfull.

Since I am not using mpf-mc I didn't dig into making it working (same for the monitor)

I've been running MPF, MC, and Monitor on Python 3.9.6 for a while, using a virtual environment, as well as on 3.8.12 using PyPy (but not MC). The jump to 3.10 is more difficult because of substantial changes, but our goal is to track MPF support with the default Debian.

To the OP, a search of the error you found returns this stack overflow article: https://stackoverflow.com/questions/65447314/attributeerror-module-sipbuild-api-has-no-attribute-prepare-metadata-for-bui which indicates an issue with PyQt5 and possible steps to resolve. Hopefully that can get you moving forward!

Hi All,

I got this working eventually.

The instructions in the stackoverflow  link worked to get rid of the error. So install the qt5 dependancies with:

sudo apt-get install qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools

Next hurdle was the newest version of python installs  a pyqt5-5.15.2 version and mpf-monitor wants 5.14.2 and it has a conflict, (the install is a == not a >) so you need to uninstall the 5.15.2 version before installing mpf-monitor. And because this is installed as a sip-build its not the easiest to remove.

Hope this helps anyone in the future.

Keep on flippin!
