Problem during installation / setup

[sammie76-2]

Hello! I am trying to install Sonos Kids Controller.

During the setup when starting the command "ionic build --prod" this error message appears:

An unhandled exception occurred: NGCC failed.
See "/tmp/ng-lyCHfB/angular-errors.log" for further details.
[ERROR] An error occurred while running subprocess ng.

        ng run app:build:production exited with exit code 127.

The error log says:

Can you give me an advice? Thanks a lot in advance.

How did you solved that error?

In the tsclient.json the following must be added

"enableIvy":false

Overall, it will look like this:
"moduleResolution": "node",
"importHelpers": true,
"target": "es2015",
"lib": [
"es2018",
"dom"
]
},
"angularCompilerOptions": {.
"fullTemplateTypeCheck": true,
"strictInjectionParameters": true,
"enableIvy":false
}
}
