Missing QtQuick.Controls.Styles in WebAssembly

[Dr.Stealth]

I am trying to use an CircularGauge in my project.
But the style: CircularGaugeStyle is flagged with the error "Unknown Component. (M300)".

I locked in the folder where Qt is installed and the folder .../wasm_32/qml/QtQuick/Controls/Styles is nearly empty.

I used the online installer to install this version of Qt. It is version 5.15.
I also tried to compile Qt for WebAssembly by my own. But the folder with the styles is also empty.

Can someone help me to find a solution?

I found a solution for this problem.

The import in the QML file has to look like:

import QtQuick 2.0
import QtQuick.Controls 1.4
import QtQuick.Controls.Styles 1.4

My mistake was to import the QtQuick.Controls 2.x

I also had to delete the build folder and build it from scratch.
