Patch to get vue-cli-plugin-i18n working in a mono repo

vue.config.js

const { defineConfig } = require('@vue/cli-service');
const path = require('path');

module.exports = defineConfig({
  chainWebpack: (config) => {

    // Fix vue-cli-plugin-i18n broken path to the locales folder in a mono repo
    config.module
      .rule('i18n-resource')
      .include.clear().add(path.resolve(__dirname, 'src/locales'));
    
  },
  pluginOptions: {
    i18n: {
      locale: 'en',
      fallbackLocale: 'en',
      localeDir: 'locales',   // in a  mono repo this resolves an invalid path - like  /User/bob/repo_root/src/locales - rather than /User/bob/repo_root/packages/package_root/src/locales
      enableLegacy: false,
      compositionOnly: true,
      fullInstall: false,
      runtimeOnly: true 
    }
  }
});
