QML Singleton Errors

I have "pragma Singleton" as the first line of MySingleton.qml, main.qml contains "import MyNewSingleton 1.0" and qmldir contains "singleton MyNewSingleton 1.0 MySingleton.qml" and is in the common directory.

The line "import MyNewSingleton 1.0" is underlined in red in Qt Creator and has the message "QML module not found."

When I run the project I get the message

qrc:/qml/main.qml:2:1: module "MyNewSingleton" is not installed

I also tried to import "." but that didn't work.

Code example is attached
