react-i18next throwing webpack error when initializeing using @babel/runtime 7.3.0

[guiyep]

since the dependency with @babel/runtime is anything from 7.1.2 with the latest update on @babel/runtime 7.3.0 (today) the library stops working. Had to manually downgrade the version to 7.1.2 to make the library work again.

? do you build react-i18next yourself? the runtime gets embedded during build time - so you should not really need/depend on it?

can you give a little more information what you are doing - and how you run into this?

[jamuhl]

Just updated all dependencies -> as i guess it might be related to babel-runtime update

did a republish of [email protected] does using that resolve your issue?

I guess I'm having a related problem. Just started a brand new create-react-app project yesterday, installed react-i18next and i18next and reused the same code I was using in another project. But today I'm getting the following error.

Uncaught TypeError: Cannot convert undefined or null to object

could you try with [email protected]

I'm getting the exact same issue as described before. Not cloning the repo just npm installing it and then initialising it as follow:

import { reactI18nextModule } from 'react-i18next';

// i18next configuration
const config = {
  resources,
  fallbackLng: 'en-AU',
  lng: 'en-AU',
  keySeparator: false,
  interpolation: {
    format(value, format, lng) {
      return formatterExecutor(allFormatters, value, format, lng);
    },
    escapeValue: false,
  },
};
const i18next = i18n.use(reactI18nextModule).init(config);

this all started to happen as soon as we did a fresh install of out app that was downloading the latest version of @babel/runtime 7.3.0 if I force to install first an older version before react-I18next is installed the issue do not happens.

[jamuhl]

still an issue with [email protected] ?!? should not be the case as confirmed by #686

beside that please be aware const i18next = i18n.use(reactI18nextModule).init(config); here i18next will be a Promise not the i18next instance if using i18next >= v13.0.0

Hi @jamuhl . Thanks for the support. Setting the version of react-i18next to 9.0.7 fixed the problem for me.
