Can you share the folder structure of ~/develop/mobile?

[nevardreik]

Sure - at a high level:

mobile
|- app
  |- App_Resources
  |- main.ts
  |- app.module.ts
  |- app.component.ts
  |- app.component.html
  |- app.scss
|- nativescript.config.ts
|- package.json
|- package-lock.json
|- tsconfig.json
|- tsconfig.esm.json
|- tsconfig.tns.json
|- webpack.config.json

Ok, that looks normal - contents of package.json? Perhaps if you could share the project (you can send the zip to igor@nstudio.io) I could debug it easier!

Hey Igor, I've sent you an email with details to sample project. Thanks!

@nevardreik Thanks - I was able to track down the issue, and released a fix to @nativescript/doctor - the main cause was the ~7.0.0 version in the package.json for the android runtime - semver.valid throws on ranges - but that should be fixed now.

The latest master with this change has been auto-released as 7.0.6-2020-09-06-123725-14246 but I will be releasing a patch version today/tomorrow with other fixes I do.

Nice one, thank you @rigor789!
