如何用pyrcc5编译resources.qrc文件

Question

I am trying to make a plugin for QGIS 3(I am using Windows 10) but before it is created one step before it shows this message :

"The resource compiler pyrcc5 was not found in your path. You'll have to manually compile the resources .qrc file with pyrcc5 before installing your plugin".

This is a setback because after setting a plugin path in pyqgis it deploys but the plugin says it cannot find the class module.

I have managed to make a plugin but it says error when calling its classFactory() method thus i think this is because I fail to compile the pyrcc5.

It brings this error upon after selecting it couldn't load plugin 'remove_feature' due to an error when calling its classFactory() method :

ModuleNotFoundError: No module named 'remove_feature.resources' 
Traceback (most recent call last):

Answer 1

From the OSGeo4W Shell, run qt5_env.bat and py3_env.bat . Then, change the directory to

C:\\Users\\Arnold Kilaini M\\AppData\\Roaming\\QGIS\\QGIS3\\profiles\\default\\python\\plugins\\mmqgis".

Run pyrcc5 -o resources.py resources.qrc

Also, I found the link to a gis.stackexchange question related to yours:

Hope this helps!

Answer 2

With this .bat I don't have any problem aymore.

@echo off
SET QGIS_ROOT=C:\GIS\QGIS
call "%QGIS_ROOT%"\bin\o4w_env.bat
call "%QGIS_ROOT%"\apps\grass\grass78\etc\env.bat

path %PATH%;%QGIS_ROOT%\apps\qgis\bin
path %PATH%;%QGIS_ROOT%\apps\grass\grass78\lib
path %PATH%;C:\GIS\QGIS\apps\Qt5\bin
path %PATH%;C:\GIS\QGIS\apps\Python37\Scripts

set PYTHONPATH=%PYTHONPATH%;%QGIS_ROOT%\apps\qgis\python
set PYTHONPATH=%PYTHONPATH%;%QGIS_ROOT%\apps\Python37\lib\site-packages

set PYTHONHOME=%QGIS_ROOT%\apps\Python37
set QT_PLUGIN_PATH=%QGIS_ROOT%\apps\qgis\qtplugins;%QGIS_ROOT%\apps\qt5\plugins

set PATH=C:\Program Files\Git\bin;%PATH%

cmd.exe

Answer 3

for Ubuntu users, i tried this and it didn't work out:

pb_tool compile

also tied to install python-qt5 and Ubuntu 20.04 couldn't find it, then used

sudo apt install pyqt5-dev-tool

then pb_tool compile and it worked.
