Node.js-我啟動npm start時babel loader出現錯誤

Question

收到此錯誤：

在多主模塊中找不到錯誤：錯誤：無法在C：\\ Users \\ username \\ Deskto p \\ reactApp @多主模塊中解析模塊“ react”

module.exports = config; 
var config = {
    entry: './main.js',
    output: {
        path:'./',
        filename: 'index.js',
    },
    devServer: {
        inline: true,
        port: 8080
    },
    module: {
        loaders: [{
            test: /\.jsx?$/,
            exclude: /node_modules/,
            loader: 'react',    
            query: {
                presets: ['es2015', 'react']
            }
        }]
    }
}

節點版本-4.4.7

npm版本-3.10.5

Babel全局加載npm install -g babel npm install -g babel-preset-react

您可以嘗試將裝載機更改為“ Babel”

module.exports = config; 
var config = {
    entry: './main.js',
    output: {
        path:'./',
        filename: 'index.js',
    },
    devServer: {
        inline: true,
        port: 8080
    },
    module: {
        loaders: [{
            test: /\.jsx?$/,
            exclude: /node_modules/,
            loader: 'babel',    
            query: {
                presets: ['es2015', 'react']
            }
        }]
    }
}

這就是我的設置方式，它對我有用。

編輯：

這是我完整的webpack設置：

module.exports = {
  entry: [
    './src/index.js'
  ],
  output: {
    path: __dirname,
    publicPath: '/',
    filename: 'bundle.js'
  },
  module: {
    loaders: [{
      exclude: /node_modules/,
      loader: 'babel',
      query: {
        presets: ['react', 'es2015', 'stage-1']
      }
    },{
      include: /\.json$/,
      loaders: ["json-loader"]
    },{
      test: /(\.css)$/, loaders: ['style', 'css']
    }]
  },
  resolve: {
    extensions: ['', '.json', '.js', '.jsx']
  },
  devServer: {
    historyApiFallback: true,
    contentBase: './'
  }
};

具有與babel和webpack相關的以下依賴項（不是完整列表）

  "devDependencies": {
    "babel-core": "^6.2.1",
    "babel-loader": "^6.2.0",
    "babel-preset-es2015": "^6.1.18",
    "babel-preset-react": "^6.1.18",
    "webpack": "^1.12.9",
    "webpack-dev-server": "^1.14.0"
  },
  "dependencies": {
    "babel-preset-stage-1": "^6.1.18",
