"QtQuick version 2.0 is not installed" while trying to run CurrencyConverter Example for Ubuntu Phone

You are using qmlviewer when you should be using qmlscene. Quote from the tutorial:

To start QML applications, either during the prototyping or final stages, you will use QML Scene. QML Scene is a command-line application that interprets and runs QML code.

...

Here's a tip: although Qt Creator does not yet support qmlscene as QML viewer, you can invoke it from within the IDE. Here’s how:

1. In Qt Creator, go to Tools > Options…
2. Choose the External Tools tab, then in the pane select the Preview (qmlviewer) entry
3. On the Executable: field on the right, replace the contents with /opt/qt5/bin/qmlscene.
4. Optionally change the command name by double-clicking on the Preview (qmlviewer) entry from above. You can call it Preview (qmlscene).
5. Click on OK to save the changes.

You can also run QML Scene from the command line:

$ qmlscene /path/to/application.qml

Hi~ I had the same problem like yours that Qt Creator throughs the error message

(module "QtQuick" version 2.0 is not installed).

And I was also following the step-by-step guide just like you. Finally I have fixed it now. this image shows that you have something wrong in configuration the qmlscene. I also had configured the qmlscene, but it had the same error like you had done.

Finally I found that when I configured the path of qmlscene , I had typed a backspace before the "/opt/qt5/bin/qmlscene" . So it didn't work. I just want to tell you what I've done to cause this error. :)
