@shineklbm I had the same issue, here's an a vue reference I found vuejs/vue-cli#4177

If you're using Nativescript-Vue CLI like I am, it seems there's some major issues that arose over the last 24 hours.

any update here? I am still getting this error

I was able to resolve this issue, by running the npm ci (clean install) instead of npm install or tns install. I think it is happening due to some node modules update. Anyway thanks for the support.

@shineklbm try executing uninstall before updating (or as shown above use clean install)

npm uninstall -g nativescript
npm i -g nativescript

Hey all,
The error indicates you are using one of the next versions of nativescript-dev-webpack. As we are preparing the next major version of NativeScript (6.0.0), the next version of nativescript-dev-webpack is compatible only with it. So you should either use next versions of both CLI and nativescript-dev-webpack or their official versions.

NOTE: Do not forget to update your webpack.config.js when changing nativescript-dev-webpack versions, i.e. after installing the new version, execute ./node_modules/.bin/update-ns-webpack --configs
