It seems I have the dependency installed but still have an import problem.
Do you have suggestions?

I’ve just updated to the current version (2.18.5 on Windows) of QGIS, in the hope of getting rid of the above error, without success. Some time ago I tried to install the QField Sync plugin, which I believe was the first time I saw this error.

One thing I notice is the weird file path apps/qgis/./pythonqgis, it’s got slashes going both ways and a dot in the middle! If you ignore the weirdness the path does exist though.

Trying to install PyQt5, the »make install» command ended by issuing a warning related to pyuic5 file format (see bellow)

the python path is set as

PYTHONPATH=/usr/lib/python3.2/site-packages/PyQt5

When testing I face these issues

modules not found

help('modules')

doesn’t display any PyQt5 module

Conversion error

Trying to convert a .ui file to a python module

$  pyuic5 mywindow.ui -o mywindow_ui.py

results in

/usr/bin/python3: No module named PyQt5.uic

Can’t convert UI nor embedded QT resources anymore (pyrcc5 fails as pyuic5)

Build

the build seems succesfull as the /usr/lib/python3.2/site-packages directory content is

Any idea to solve that ?

This bug affects 1 person

@JonB said in I can’t import .ui file: No module named error:

@hernancrespo89
This is way thrown out there on a hunch: if the file named histogram shown in the UI is relevant, why is not named histogram.py?

this is my reference, and there is no histogram.py there.

And please copy & paste the full text (we can’t see the top) of the traceback here (not screenshot).

Here is the full traceback:
