Environment I`m running NativeScript on Windows 10 Pro 64bits, the ns info:

√ Getting NativeScript components versions information… √ Component nativescript has 6.5.0 version and is up to date. √ Component tns-core-modules has 6.5.1 version and is up to date. ‼ Update available for component tns-android. Your current version is 6.3.1 and the latest available version is 6.5.0. ‼ Update available for component tns-ios. Your current version is 6.3.0 and the latest available version is 6.5.0.

Describe the bug I run “tns debug android --emulator --env.sourceMap --env.uglify --env.envtype=dev” and after the message bellow the error described popup

Searching for devices... Preparing project... File change detected. Starting incremental webpack compilation... webpack is watching the files…

To Reproduce

`rm -rf node_modules/ platforms/ sourceMap/ package-lock.json hooks && npm i && tns install

tns debug android --emulator --env.sourceMap --env.uglify --env.envtype=dev`

Expected behavior

My problem ended up being a path entry in my tsconfig.json file. I had …

        "paths": {
            "~/*": [
                "src/*"
            ],
            "*": [
                "./node_modules/*"
            ]
        }

… and if I remove the node_modules one it works, my working tsconfig.json file has paths …

        "paths": {
            "~/*": ["src/*"]
        }

@limyandi Well, I don’t really know. If I remember right I was comparing my test repo to others I knew about and trying every little difference I saw and came upon this fix that way. And since that paths entry did not seem to negatively affect anything (for me) I just made the change and moved on. Sorry I can’t be of more help.
