Vite 5 Import assertions are not a stable feature of the JavaScript language.

[eguvenc]

I get this warnings when i try to install vuetify() plugin for Vite 5

Here is the demo repo. https://github.com/eguvenc/vite5/

ExperimentalWarning: Import assertions are not a stable feature of the JavaScript language. Avoid relying on their current behavior and syntax as those might change in a future version of Node.js

Here is my vite.config.mjs file.

// Plugins

bump..

[agentschmitt]

found similar issue here: https://github.com/vuetifyjs/vuetify-loader/issues/326 i also got into this issue after updating to vite@5 & vite-plugin-vuetify@2

only option i found until now is to disable warnings for nodejs with enviroment variable NODE_NO_WARNINGS=1 but this will hide all warnings not only the experimental stuff :(

[eguvenc]

thanks i use this solutions for now
