Additionally after all other methods failed I have tried providing the plugin but all methods have given the same resulting error

Can you show what you did using the comments from the article?

vilage free answered 3 years ago

I'm having the exactly same issue on Pro version. When i install the free version, it works, so, i don't think it's our project configuration.

Can you, developer guys, help us?

Mikołaj Smoleński staff answered 4 years ago

In webpack applications mdb should be added as a global alias.

Here's the necessary config:

new Webpack.ProvidePlugin({
  'mdb': 'mdb',
}),

and:

  resolve: {
    alias: {
      '~': Path.resolve(__dirname, '../src'),
      'mdb': Path.join(__dirname, '../node_modules/mdb-ui-kit'),
    },
  },

I recommend to check our Webpack Starter.

Best regards

I've added everything but no matter what I get Module not found: Error: Can't resolve 'mdb' in '/vagrant/node_modules/mdb-ui-kit/js' that path is correct to the js folder

Mikołaj Smoleński staff commented 4 years ago

It seems there is a problem with your project's configuration and we can't help with it since we don't guarantee Rails integration. Still, I suggest to compare your configuration with our Webpack starter config. Best regards

And where should I enter this configuration - in what file?
