Rails/Webpacker is not working

I have a Rails/React project. It's using Rails/webpack 3.3.0. To precompile react code, I executed:

rails assets:precompile RAILS_ENV=development

But I am getting this error:

[Webpacker] Compilation failed:

(node:47256) DeprecationWarning: Tapable.apply is deprecated.

Call apply on the plugin directly instead (node:47256) DeprecationWarning:

Tapable.plugin is deprecated. Use new API on .hooks instead

TypeError: dep.getResourceIdentifier is not a function

Is this something you faced before? Would you like to help me to fix thsi problem?

Here is my package.json

  "dependencies": {
    "@rails/webpacker": "3.3.0",

The version of Webpacker you are using isn't compatible with Webpack 4.

However, it looks like support is close, Webpack 4.x support has been merged: https://github.com/rails/webpacker/pull/1316

And there's a Webpacker 4.x preview release: https://rubygems.org/gems/webpacker

So I believe you want to use Webpack 3.x for the time being, or go bleeding edge and try the prerelease.

With that said, I'm going to give the prerelease a go, I've been waiting for Webpack 4.x support!
