跟踪：节点类型SpreadProperty已在Object.isSpreadProperty处重命名为SpreadElement。

Question

我正在启动一个React应用，这是我的Webpack配置：

'use strict'

const ExtractPlugin = require('extract-text-webpack-plugin')
const HTMLPlugin = require('html-webpack-plugin')
module.exports = {
    devtool: 'eval',
    entry: `${__dirname}/src/main.js`,
    output: {
        filename: 'bundle-[hash].js',
        path: `${__dirname}/build`,
        publicPath: '/',
    },
    mode: 'development',
    performance: {
        hints: false
    },
    plugins: [
        new HTMLPlugin(),
        new ExtractPlugin('bundle-[hash].css'),
    ],
    module: {
        rules: [
            {
                test: /\.js$/,
                exclude: /node_module/,
                loader: 'babel-loader',
            },
            {
                test: /\.scss$/,
                loader: ExtractPlugin.extract(['css-loader', 'sass-loader']),
            },
        ],
    },
}

然后，我有一个package.json文件，这是依赖项：

"devDependencies": {
    "@babel/core": "^7.1.6",
    "@babel/plugin-proposal-object-rest-spread": "^7.0.0",
    "@babel/preset-env": "^7.1.6",
    "@babel/preset-react": "^7.0.0",
    "and": "0.0.3",
    "babel-cli": "^6.26.0",
    "babel-core": "^7.0.0-bridge.0",
    "babel-loader": "^8.0.4",
    "eslint": "^5.9.0",
    "install": "^0.12.2",
    "jest": "^23.6.0",
    "npm": "^6.4.1",
    "webpack-cli": "^3.1.2"
  },
  "dependencies": {
    "babel-plugin-transform-object-rest-spread": "^6.26.0",
    "babel-plugin-transform-runtime": "^6.23.0",
    "babel-preset-env": "^1.7.0",
    "css-loader": "^1.0.1",
    "extract-text-webpack-plugin": "^4.0.0-beta.0",
    "html-webpack-plugin": "^3.2.0",
    "node-sass": "^4.11.0",
    "react": "^16.6.3",
    "react-dom": "^16.6.3",
    "resolve-url-loader": "^3.0.0",
    "sass-loader": "^7.1.0",
    "webpack": "^4.25.1",
    "webpack-dev-server": "^3.1.10"
  }

我尝试了很多方法来将babel软件包更新到第7版，更改babelrc配置，无论如何。

该项目虽然可以编译，但是在编译开始时会收到以下消息：

跟踪：节点类型SpreadProperty已在Object.isSpreadProperty处重命名为SpreadElement。

大约有几百行。在打印完所有行之后，编译过程将继续并成功完成。

那是什么，我如何摆脱这些行？

这是为我解决问题的最终设置。

.babelrc

{
  "presets": [
    "@babel/preset-env",
    "@babel/preset-react"
  ],
  "plugins": [
    "@babel/plugin-proposal-object-rest-spread"
  ]
}

为了更好地理解，这是我的package.json的 devDependencies ：

"devDependencies": {
    "@babel/core": "^7.1.6",
    "@babel/plugin-proposal-object-rest-spread": "^7.0.0",
    "@babel/plugin-transform-object-assign": "^7.0.0",
    "@babel/plugin-transform-react-jsx": "^7.1.6",
    "@babel/preset-env": "^7.1.6",
    "@babel/preset-react": "^7.0.0",
    "babel-loader": "8.0.4",
    "prop-types": "15.6.2",
    "react": "^16.6.3",
    "react-dom": "^16.6.3",
    "style-loader": "^0.23.1",
    "utils": "^0.3.1",
    "webpack": "4.26.1",
    "webpack-cli": "3.1.2",
    "webpack-dev-server": "^3.1.10"
  }

这是我的 webpack.config.js 模块的部分：

module: {
        rules: [
            {
                test: /\.(js|jsx)$/ ,
                exclude: /node_modules/,
                loaders: "babel-loader"
            }
        ]
    }
