I've cloned a sample python project and tried to build and run it. But sailfish-qml doesn't exist and I can't run the sample.

Previously I installed pyotherside-qml-plugin-python3-qt5 manually:

[root@Jolla nemo]# pkcon install pyotherside-qml-plugin-python3-qt5
Waiting in queue                                                               
Refreshing software list                                                       
Resolving dependencies                                                         
Installing packages                                                            
Waiting in queue

Installing packages

Also I tried to run sample via terminal:

[root@Jolla nemo]# sailfish-qml pythonsample
bash: sailfish-qml: command not found

and install sailfish-qml

[root@Jolla nemo]# pkcon install sailfish-qml
Command failed: This tool could not find any available package: could not find sailfish-qml

How to build and run python apps correct?

Thanks in advance!

The example project does not work correctly, I found the way to use pyotherside in Sailfish QML. This took me several days until I fully understand why...

Warning: only Python 3 is supported! I never found a way to get my code running on Python 2...

First in your QML you import this:

import io.thp.pyotherside 1.3

They use 1.4 but that's not allowed in Harbour!

Then you can add the 'Python {}' to your QML:

    id: python

        // Import the pad where you Python file is stored. In this case: /qml/pages

        // Import the module, the name = name of your Python script.
        importModule('pythonModule', function () {});

        // Receive here data from Python by using: pyotherside.send('receiver', data)
        setHandler('receiver', function(data) {
            // Do some stuff here with the data and QML.

        // when an exception is raised, this error handler will be called
        console.log('python error: ' + traceback);

        // All the stuff you send, not assigned to a 'setHandler', will be shown here:
        console.log('got message from python: ' + data);

If you want to use pyotherside in your project make sure you add it to your .yaml file as a dependency under 'Requires':

- sailfishsilica-qt5 >= 0.10.9 
- pyotherside-qml-plugin-python3-qt5 >= 1.3.0

I never run it from the terminal, I deploy it with the SDK as an RPM package. In this case your app shows up as a normal app in the app grid and is started automatically after deploying.

Thanks! I edited the project but the problem is same. I found that libsailfishapp-launcher should be in Requires section. I added this line and received follow error: Error: File './oss/armv7hl/libsailfishapp-launcher-1.0.10-10.7.1.jolla.armv7hl.rpm' not found on medium ''. When I tried to install this package via pkcon manually I got the same error.

I never had that error before, Sailfinder (in the Jolla Store) uses heavily Python and I only added one line to Requires.

do pkcon refresh before manipulating with repos

@coderus: It helped. Thanks!
