tns run can get stuck in a loop since 2.5

[tjvantoll]

Since upgrading to NativeScript 2.5 I’ve occasionally hit this odd problem where tns run ios gets stuck in a loop.

That is, after I make a change to my app I keep seeing these four lines outputted continuously:

Transferring project files...
Unable to sync files. Error is: ENOENT: no such file or directory, stat '/Users/tj/Desktop/HelloWorld/platforms/ios/HelloWorld/app/tns_modules/adm-zip/adm-zip.js'
Skipping prepare.

The specific file is sometimes different, but it’s always something in tns_modules. I’m going to try to get better recreation steps for you because I know this is a bit vague, but I thought I’d let you know that I’m hitting this.

I’m actually getting this on Android now too. In this case I’m doing:

tns create Groceries --template nativescript-template-ng-groceries
cd Groceries
tns run android

After that I wait a few seconds and then I start seeing these lines repeating.

Transferring project files...
Unable to sync files. Error is: ENOENT: no such file or directory, stat '/Users/tj/Desktop/Groceries/platforms/android/src/main/assets/app/tns_modules/babel-types/.npmignore'
Skipping prepare.

same here with vanilla NS and scss files .. on android

Transferring project files...
Unable to sync files. Error is: Multiple exceptions were thrown:
ENOENT: no such file or directory, stat '<...>/platforms/android/src/main/assets/app/styles/_common.scss'

@tjvantoll I managed to reproduce the problem. It happens when you try to change a dev-dependency in the node_modules.
We are watching the whole node_modules folder, but we don't push dev-dependencies on the device.
So when you change a dev-dependency, livesync fails to find the file, because the prepare step ignores all files that are a dev-dependency.
