Can't make console warning about feature flag globals disapear

[wladston]

I have this warning in my console in dev mode:

You are running the esm-bundler build of vue-i18n. It is recommended to configure your bundler to explicitly replace feature flag globals with boolean literals to get proper tree-shaking in the final bundle.

I can't get rid of it…

I'm currently in the process of migrating my app from Webpack to Vite. In webpack, I had this in my config:

        plugins: [

            new webpack.DefinePlugin({
                __VUE_OPTIONS_API__: true,
                __VUE_PROD_DEVTOOLS__: false,
                __VUE_I18N_FULL_INSTALL__: true,
                __VUE_I18N_LEGACY_API__: true,
                __INTLIFY_PROD_DEVTOOLS__: false
            }),

That made the warning disapear. Now when using Vite, the warning is back, despite the documentation saying these variables are automatically set when using Vite. So I tried to add the variables on Vite, but it didn't make the warning go away. My vite.config.js looks like this:

export default {
    define: {
        __VUE_OPTIONS_API__: true,
        __VUE_PROD_DEVTOOLS__: false,
        __VUE_I18N_FULL_INSTALL__: true,
        __VUE_I18N_LEGACY_API__: true,
        __INTLIFY_PROD_DEVTOOLS__: false
    },
    …

I tried replacing the booleans for strings ('true' instead of true) and it also didn't work.

How can I get rid of the warning in the console?

I'm on vue-i18n@9.1.9 and @intlify/vite-plugin-vue-i18n@3.2.1. I spend some time trying to build a minimal example of the problem, but I coudn't find an example boilerplate to use…

vue-i18n v9.1.9 has a bug that cannot remove warning.
You can avoid it with using the vue-i18n v9.2-beta latest version

Thanks! It worked :) I just had to add an overrides key to my package.json and it worked!

  "overrides": {
    "@intlify/vite-plugin-vue-i18n" : {
      "vue-i18n": "9.2.0-beta.30"
    }
  },
