debug has stopped working after updating

[ishandutta2007]

The following is output on selecting launch on android

• Why is the debugger trying to install tns-android? It wasn't like this before.
• Why is it not finding the command: tns --analyticsClient VSCode debug android --no-client --watch , it shows: The tns command finished its execution with code 127 ?
• I believe no-client and watch options were not there in documentations of earlier versions either and were reserved for VSCode. I kept it as default launch which is { "name": "Launch on Android", "type": "nativescript", "request": "launch", "platform": "android", "appRoot": "${workspaceRoot}", "sourceMaps": true, "watch": true } . So what changes makes throw code 127 ?
• 31;1mException: The plugin [email protected] is already installed, yes obviously the plugin is already installed, why are you trying to install it now, ok fine say you want to run again but why should it fail the actual command ?

Hi @ishandutta2007
It seems that this is a known CLI issue. You can try the solution proposed in the original issue.

I am closing this one because of duplication with NativeScript/nativescript-cli#2487.
