I have an PyQt5.QtWebEngineWidgets error, when I'm trying to use Qgis2threejs

[enoch777]

I have an error with Missing dependencies related to PyQt5 and QtWebkit.

The window says:

Please install "python3-pyqt5.qtwebkit" package (Debian/Ubuntu) before using this plugin

Then, another windows:

ModuleNotFoundError: No module named 'PyQt5.QtWebKit'

I did:

sudo port install py-pyqt5 +webengine +webkit

But the problem is still there

Assuming you are have installed qgis3-ltr with default Python 3.11 bindings, try:

sudo port install py311-pyqt5 +webkit

@enoch777 Did you have opportunity to test my suggestion?

[enoch777]

Yes, I tried suggestion. But, it doesn't work. Finally, I uninstalled everything as described in the guide at the following link: ​https://guide.macports.org/chunked/installing.macports.uninstalling.html. Then, I reinstalled MacPorts, then I do sudo port install qgis3-ltr, but now i have a new problem:

---> Building qgis3-ltr Error: Failed to build qgis3-ltr: command execution failed Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_gis_qgis3/qgis3-ltr/main.log for details. Error: Follow ​https://guide.macports.org/#project.tickets if you believe there is a bug. Error: Processing of port qgis3-ltr failed

[enoch777]

main.log result from sudo port install qgis3-ltr

[nilason (Nicklas Larsson)]

According the log file you have also homebrew installed and that is making the build fail. You probably need to uninstall homebrew (or if possible inactivate it).

[enoch777]

Well, I uninstall homebrew. And now I have Qgis again =) I tried: sudo port install py311-pyqt5 +webkit And I still have the initial problem, a window with this message: Missing dependencies related to PyQt5 and QtWebKit. Please install "python3-pyqt5.qtwebkit" package (Debian/Ubuntu) before using this plugin. And then the error:

ModuleNotFoundError: No module named 'PyQt5.QtWebKit'

There is a bug with py3xx-pyqt5 +webkit, see ​https://trac.macports.org/ticket/68073.

[enoch777]

Thank you very much. Well, we'll have to wait for it to be resolved. Other than that, everything is working fine =)

[nilason (Nicklas Larsson)]

The fix is now ​committed, please try py311-pyqt5 +webkit again.

[enoch777]

Thank you!!! Well, at first it did not work. Then, I uninstalled everything to reinstall all again, and after that... it works!!!

Replying to nilason:

The fix is now ​committed, please try py311-pyqt5 +webkit again.

Glad it did it!

I'm not sure what you mean with "everything", but if that meant a reinstallment of MacPorts it was most likely unnecessary. It is crucial to update locally the state and changes of the "port tree" (after a bug fix or other update), this you do with sudo port selfupdate, from there on you can (re-)install a problematic port. Sometimes it is necessary to clean up the build locally with e.g. sudo port clean py311-pyqt5.
