Error: Webpack 2 can't resolve babel-loader

I run into the following error message when tried to set up webpack 2 with babel:

ERROR in Entry module not found: Error: Can't resolve 'babel-loader' in 'path_to_project_dir'

The configuration file following the webpack 2 docs:

const path = require('path')

const config = {
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'bundle.js'
  },
  module: {
    rules: [
      {
        test: /\.jsx?$/,
        exclude: [
          path.resolve(__dirname, 'node_modules')
        ],
        loader: 'babel-loader',
        options: {
          presets: ["es2015"]
        },
      }
    ]
  },
  resolve: {
    modules: [
      'node_modules',
      path.resolve(__dirname, 'src')
    ],
    extensions: ['.js', '.json', '.jsx'],
  }
}

module.exports = config

I have the following dev dependencies in my packages.json:

"devDependencies": {
  "babel-core": "^6.24.0",
  "babel-loader": "^6.4.0",
  "babel-preset-es2015": "^6.24.0",
  "path": "^0.12.7",
  "webpack": "^2.2.1",
  "webpack-dev-server": "^2.4.1"
},

My node and npm versions are:

node 7.7.1
npm 4.4.1

My OS is macOS Sierra

What could be the source of this error message, and how should I solve it. I tried a lot of tutorials and blog posts to find a solution but none of them worked.

I investigated the node_modules directory and found a lot of dependencies missing. I deleted the node_modules directory and yarn.lock file and from a new Terminal window ran the yarn command.

It worked, installed all the dependencies, and webpack 2 & babel worked as it should.

As originally I installed the npm modules with atom editor's term3 terminal, I tried to do the same reinstall there, however it produced missing dependencies as originally.

So the error has been caused by the term3 package of atom

Solution: use the standard terminal, and DON'T use the terminal provided by the term3 package of atom
