Unsolved Automatic type dump of QML module failed

[sosun]

I want to import external modules. For this I've edited importPaths like importPaths: [ "/usr/lib/qt/qml" ]. It's the folder where my modules located, here's the proof:

1st screen

2nd screen

3rd screen

Here's the example of Components' s qmldir:

The same output goes for every module and it's absolutely same(excluding the names), therefore I won't include it here for readability purposes
