多应用程序中的错误：将babel升级到v7后无法解析模块“ babel-loader”

Question

It seems I've got all that is needed installed, but still cannot make it work.

Here's my package.json:

    "babel-core": "^7.0.0-bridge.0",
    "babel-jest": "^23.4.2",
    "babel-loader": "7.1.1",

Then, I have a webpack.config.js file for configuring webpack. There's the fragment that causes problems:

webpackConfig.module.loaders = [{
  test    : /\.(js|jsx)$/,
  exclude : /node_modules/,
  loader  : 'babel-loader',
  query   : project.compiler_babel
}, {
  test   : /\.json$/,
  loader : 'json'
}];

anything I type instead of 'babel-loader' as a value of loader key will be mentioned in the error message in the place of "babel-loader".

And I also have project.config.js where the query leads:

compiler_babel : {
    cacheDirectory : true,
    plugins        : ['transform-runtime'],
    presets        : ['es2015', 'react', 'stage-0']
  }, 

I have also tried to work with babel.config.js, with configuration from compiler_babel, but did not get the way with it.

Any ideas how can I make it work? I'm planning to write some test in jest for react application, therefore I need some newer babel packages.

PS The precise error message:

ERROR in multi app Module not found: Error: Cannot resolve module 'babel-loader' in ... @ multi app

and my webpack version is "webpack": "^1.15.0",

Check the documentation . You need babel-loader v8 with Babel v7.
