问题
I try to extend Angular with Nativescript (instructions). But when I try to add nativescript-schematics (ng add @nativescript/schematics) I always get the message "File angular.json could not be parsed!":
+ @nativescript/schematics@0.5.0

Reading Project Settings
Project settings:
{

"sourceRoot": "src",
"mainName": "main",
"mainPath": "src/main.ts",
"tsConfig": "src/tsconfig.app.json",
"entryModuleClassName": "AppModule",

"entryComponentImportPath": "./app.component",
"entryComponentName": "App",
"entryComponentPath": "\\src\\app\\app.component.ts",

}
Adding @nativescript/schematics to angular.json
File angular.json could not be parsed!
But I dont understand why there is a error. My Angular.json currently looks like this:

I use the following versions:
- Angular/cli 7.2.1
- Nativescript 5.1.0
- Typescript 3.1.6
And my operating system is Win10
Thank you for your help

Your angular.json file's content is not valid.
In this case, you can find the issue with any JSON parser tool:
http://json.parser.online.fr/
https://jsonformatter.org/json-parser
Paste your angular.json file's content into the input, then you'll see where's the issue.
