Plugin not working after building through Plugin Builder in QGIS

Question

I have been trying to build a plugin through Plugin Builder 3 and been facing this issue then.

I have been facing the pyrcc5 issue but I was able to solve it through this link: Fixing “The resource compiler pyrcc5 was not found”

This is the Python error:

Couldn't load plugin split_layer' due to an error when calling its classFactory() method

ModuleNotFoundError: No module named 'split_layer.resources'
Traceback (most recent call last):
  File "C:/PROGRA-1/QGIS3~1.3/apps/qgis/./python\qgis\utils.py", line 334, in _startPlugin
    plugins [packageName] = package.classFactory (iface)

    from .split_layer import Split_Layer

    mod = _builtin_import (name, globals, locals, fromlist, level)
ModuleNotFoundError: No module named 'split_layer.resources'

Can anyone help me how to solve this error?

While building a plugin for QGIS using Plugin Builder, if you get ModuleNotFoundError: No module named '... .resources' error after running Makefile, you should first check if resources.py exists in the folder (source folder) created by Plugin Builder. If it does, copy that file into your plugin folder in QGIS plugin folder (target folder).

If there is no resources.py file in the source folder, then, run next code to create resources.py from resources.qrc.

pyrcc5 -o resources.py resources.qrc

And copy resources.py file into target folder or run Makefile again.

Note: You can copy all plugin files into target folder manually without running Makefile. But still, you will need resources.py file. Therefore, you have to generate it via pyrcc5.
