在react中用babel的时候出现这种错误

Question

在package.json中关于babel下载的包

    "babel": "^6.23.0",
    "babel-cli": "^6.26.0",
    "babel-core": "^6.26.0",
    "babel-loader": "^7.1.2",
    "babel-plugin-transform-class-properties": "^6.24.1",
    "babel-plugin-transform-decorators-legacy": "^1.3.4",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-react": "^6.24.1",
    "babel-preset-react-hmre": "^1.1.1",
    "babel-preset-stage-0": "^6.24.1",
    "babel-runtime": "^6.26.0",
    "body-parser": "^1.18.2",

.babellrc

{
  "presets": ["react", "es2015", "stage-0"],
  "env": {
    "development": {
      "presets": ["react-hmre"]
    }
  }
} 

在webpack.config.js中关于js和jsx的代码

    module:{
        rules:[
            {
                test: /\.js$/,
                loader: 'babel-loader',
                exclude: /node_modules/,
                query: {
                    presets: ['react-hot-loader', 'babel']
                }
            },
           
            {
                test: /\.jsx$/,
                exclude: /node_modules/,
                loader:'babel-loader',
                query: {
                    presets: ['babel','react-hot-loader']
                }
            }
        ]
    },

我觉得可能是babel下载或者.babellrc这个文件有问题，但是查了半天，没查出来，所以问问这是什么原因导致的，怎么解决？

Answer 1

将node_modules删除，然后重新装了一遍就好了，但是还是不知道为啥

Answer 2

阔能是babel-core这个包npm的时候有问题没下好(｀・ω・´)
