Describe the bug
I’m having problems trying to run the Hello World template app using the NativeScript source as described here
When trying to run the app I get the error attached in the screenshot at the end.
To Reproduce
- clone the NativeScript project
tns create test-bkg-posin the same folder where you cloned NativeScriptnpm install --save ../NativeScript/tns-core-modulesinsede the project folder (i.e:test-bkg-pos)tns run android
Expected behavior
The project should work using the source code for core modules.
Additional context
Not to flood this issue with a wall of text, I've attached the error as an image. If it turns out the problem is cause by something I did wrong, I'll replace it with the text for others that have the same issue to find this.

@surdu the thing is that the project you are using is plain JavaScript while the NativeScript/tns-core-modules (cloned from the repo) are written in TypeScript. So you need to transpile the
tns-core-modulesso that your plain JS project will have the transpiled JS files.in NativeScript repository run
and then rebuild the test project you are good to go. The downside is that you will have to transpile the modules after each code change (in
tns-core-modules). Or usetsc -w.Another option is to grab the
tsconfig.jsonfrom a TypeScript project and use it in your plain JS project. (but then you should NOT usetsc -was it will conflict with the Webpack transpiling)surdu commentedon Oct 14, 2019
D'oh! Makes perfect sense! Thank you! I'll update the docs with this info.
