Experimental version bugs

I’m submitting a bug report

Webpack Version: 3.8.1

Babel Core Version: 7.0.0-beta.5

Babel Loader Version: 7.1.2

Please tell us about your environment: OSX 10.12

Current behavior: When running webpack after following the setup instructions it errors saying it cannot find “@babel/env”. Should the require be “@babel/preset-env” instead? When I change it to “@babel/preset-env” it errors out saying; Cannot find module babel-helper-regex'

Here’s an example of my babel-loader config. I do not use .babelrc since I have a few different webpack files and find it easier to control babel granularly this way:

{
  test: /\.js$/i,
  use: {
    loader: 'babel-loader',
    options: {
      compact: true,
      babelrc: false,
      presets: [
        ['@babel/env', {
          targets: {
            browsers: [
              'last 2 versions',
              'not IE <= 10',
            ],
          },
        }],
        '@babel/preset-react',
      ],
      plugins: [
        ['graphql-tag'],
        ['styled-components', {
          displayName: false,
        }],
        ['transform-object-rest-spread'],
        ['@babel/transform-modules-commonjs', {}],
      ],
    },
  },
  exclude: /node_modules/,
},

Note the options.babelrc: false and defining an empty object for the @babel/transform-modules-commonjs placeholder.

This seems to fix the plugin, however it’s just a workaround. Hope this helps someone! 😃

This however does not seem to fix scripts that rely on .babelrc… I am currently fighting that.
