Babel 7-преобразование декораторов не работает с babel-loader

у меня проблема с оформителями в React С mobX app. И он работает нормально с .babelrc, но и babel-loader С webpack. Я копирую конфигурацию babel в webpack config, но это не работает. Я проверил все решения, которые я могу найти в google, но все они относятся к bebelrc, а не webpack конфигурации. Мой webpack config:

const path = require('path');
const webpack = require('webpack');

module.exports = {
  devtool: 'cheap-module-eval-source-map',
  entry: [
    'webpack-hot-middleware/client',
    'babel-polyfill',
    path.join(__dirname, '../../src/web/index')
  ],
  output: {
    path: path.join(__dirname, '../public'),
    filename: 'bundle.js',
    publicPath: '/'
  },
  module: {
    rules: [
      {
        test: /.json$/,
        loader: 'json-loader'
      },
      {
        test: /.js$/,
        exclude: /node_modules/,
        loader: 'babel-loader',
        options: {
          presets: [
            ["@babel/preset-env", { "modules": false }],
            "@babel/preset-react",
          ],
          plugins: [
            [
              "@babel/plugin-proposal-decorators",
              {
                "legacy": true
              }
            ],
            "@babel/plugin-proposal-optional-chaining",
            "@babel/plugin-syntax-dynamic-import",
            "@babel/plugin-syntax-import-meta",
            "@babel/plugin-proposal-class-properties",
            "@babel/plugin-proposal-json-strings",
            ["@babel/plugin-transform-runtime", {
              "helpers": true,
              "regenerator": false
            }],
            "@babel/plugin-proposal-function-sent",
            "@babel/plugin-proposal-export-namespace-from",
            "@babel/plugin-proposal-numeric-separator",
            "@babel/plugin-proposal-throw-expressions",
            "react-hot-loader/babel"
          ]
        }
      }
    ]
  },
  plugins: [
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: JSON.stringify('development'),
        PLATFORM_ENV: JSON.stringify('web')
      }
    }),
    new webpack.optimize.OccurrenceOrderPlugin(),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoEmitOnErrorsPlugin()
  ]
};

ошибка:

ERROR in ./src/web/stores/UIStore.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):
SyntaxError: /Users/alder/Projects/_apps/service_exchange/service-exchange-app/src/web/stores/UIStore.js: Decorators transform is necessary.

кажется babel-loader не работает с plugin-proposal-decorators

любой решение?

он перестал работать после того, как я удалить stage-2 из версии beta 54

обновление:

я обнаружил, что могу использовать конфигурацию babel в webpack, например:

    loader: 'babel-loader',
    options: {
      babelrc: true,
      cacheDirectory: true
    }

но это не помогло, у меня такая же ошибка.

Обновлено 2:

нашел аналогичная проблема в babel-loader repository, но это тоже не помогло.
