问题
So a few days i started this app and --watch was working just fine until today.
This is what i call: tns run android --emulator --device=ANDROID --watch
but when i change code, nothing happens, my changes are not present. When i run tns doctor, it shows that everything is up to date except ios emulator( witch i am not using at this time ).
Just tried to reinstall the app( from git - https://github.com/nestor94/my-instagram ) and re-created the avd. still --watch not working.
Thanks!
回答1:
You are using the wrong command to watch for changes try using tns livesync android --watch
回答2:
Not sure about "wrong"
Since {N} 2.5.0 we say: This command is deprecated. It will be removed in the next version of NativeScript CLI. Use the "run" command instead.
I suggest that you run tns run --help and see if you have a --watch flag .. I don't see such. and from my experience, it's syncing changes by default ( unless you're adding new libs/installs and then you need to quit & run this command again )
