我试图将ReactJS现有的项目集成到Spring-boot的项目中。我正在使用的项目已经运行良好的教程，我已经实现。
pom.xml与frontend-maven-plugin一起使用。
在我复制了我想集成的应用程序的文件之前，它工作得很好.
现在我得到了这个**错误 *：

我通过一些搜索尝试了一些变通方法，但没有成功。

yyy这是webpack.config.js：

var path = require('path');

module.exports = {
    entry: './src/main/resources/static/js/app.js',
    devtool: 'sourcemaps',
    cache: false,
    mode: 'development',
    output: {
        path: __dirname,
        filename: './src/main/resources/static/built/bundle.js'
    },
    module: {
        rules: [
            {
                test: path.join(__dirname, '.'),
                exclude: /(node_modules)/,
                use: [{
                    loader: 'babel-loader',
                    options: {
                        presets: ["@babel/preset-env", "@babel/preset-react"]
                    }
                }]
            }
        ]
    }
};

这是webpack在我尝试了一些更改之后。

var path = require('path');

module.exports = {
    entry: './src/main/resources/static/js/app.js',
    devtool: 'sourcemaps',
    cache: false,
    mode: 'development',
    output: {
        path: __dirname,
        filename: './src/main/resources/static/built/bundle.js'
    },
    module: {
        rules: [
            {
                test: path.join(__dirname, '.'),
                exclude: /(node_modules)/,
                use: [{
                    loader: 'babel-loader',
                    options: {
                        presets: ["@babel/preset-env", "@babel/preset-react"],
                        plugins : [
                                      '@babel/plugin-proposal-class-properties'
                                  ]

                    }
                }
                ]
            }
        ]
    }
};

什么都不管用。
在每个更改中，我都在Eclipse中进行Maven-update并重新开始项目。
我很乐意找到解决办法，谢谢。

也有类似的问题。软件包版本号同步后

"devDependencies": {
    "@babel/core": "^7.10.1",
    "@babel/node": "^7.10.1",
    "@babel/plugin-proposal-class-properties": "^7.10.1",
    "@babel/polyfill": "^7.10.1",
    "@babel/preset-env": "^7.10.2",
    "@babel/preset-react": "^7.10.1",
    ...

字符串
@被添加到插件名称前面（babel.config.js）

const plugins = [
    // transforms static class properties as well as properties declared
    // with the property initializer syntax
    '@babel/plugin-proposal-class-properties'
    // 'babel/plugin-proposal-class-properties' doesn't work:
    // ERROR in ./server/index.js
    // Module build failed (from ./node_modules/babel-loader/lib/index.js):
    // Error: Cannot find module 'babel/plugin-proposal-class-properties' from 
];

它运行良好。

正如@DraganS所说。我设置所有的插件与相同的版本现在它工作正常！
“@babel/core”：“^7.10.1”

很抱歉迟到的回复，但这可能会对你有所帮助，

它是自己创建的简单的webpack文件，所以你可以参考
package.json

{
  "name": "practice",
  "main": "index.js",
  "devDependencies": {
    "@babel/core": "^7.22.8",
    "@babel/plugin-proposal-class-properties": "^7.18.6",
    "@babel/preset-env": "^7.22.7",
    "babel-loader": "^9.1.3",
    "webpack": "^5.86.0",
    "webpack-cli": "^5.1.4"
  },
  "dependencies": {
    "css-loader": "^6.8.1",
    "sass": "^1.63.6",
    "sass-loader": "^13.3.2",
    "style-loader": "^3.3.3"
  }
}

字符串

webpack.config.js

const path = require('path');

module.exports = {
