Hello Michal,
I've also had this error some times ago, I do not remember if I succeed
with pyuic4, nor the solution.
But IMHO it is simpler to load "ui" files at runtime.
Here is an example from "processing" plugin :
import os
from qgis.PyQt import uic
pluginPath = os.path.split(os.path.dirname(__file__))[0]
WIDGET, BASE = uic.loadUiType(
os.path.join(pluginPath, 'ui', 'DlgConfig.ui'))
class ConfigDialog(BASE, WIDGET):
=> no need to run make or similar to create python files each time you
change something in your ui files.
load the plugin from the source folder (create a symbolic link from home
QGIS plugins dir to plugin source dir)
change something in the ui file
reload the plugin using "plugin reloader" and you immediately see the
result in QGIS.

Hi,
I'm starting with qgis plugin development on ubuntu-based Mint OS (v
18.1 Serena). I created a very simple form in Qt Designer 4.8.7 and
tried to convert it to python file with
pyuic4 -d form.ui -o form.py
This results in

If I change /usr/lib/python2.7/dist-packages/qgis/PyQt/QtCore.py line
28 to sip.setapi(api, 1), it works, QGIS starts with a following
message though:
Couldn't load PyQGIS.
Python support will be disabled.

Python version:
2.7.12 (default, Nov 19 2016, 06:48:10)
[GCC 5.4.0 20160609]
QGIS version:
2.18.7 'Las Palmas', 3b30e6a
What exactly do I have to do to make the both sides work?
