Question

使用package.json设置“主”文件时，出现实验性语法错误，如果不是，则一切正常-

我在Laravel项目中进行了预设反应，并遇到实验性语法错误，最后通过修改根package.json解决了这个问题，但是当我决定将组件分成文件夹并为每个目录使用新的package.json时，我又开始得到这个错误。从文件夹中删除package.json文件后，一切正常

root package.json

{
    "private": true,
    "scripts": {
        "dev": "npm run development",
        "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
        "watch": "npm run development -- --watch",
        "watch-poll": "npm run watch -- --watch-poll",
        "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
        "prod": "npm run production",
        "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
    },
    "babel": {
        "presets": [
            "@babel/preset-env",
            "@babel/preset-react"
        ],
        "plugins": [
            "@babel/plugin-proposal-class-properties"
        ]
    },
    "devDependencies": {
        "@babel/core": "^7.4.5",
        "@babel/preset-env": "^7.4.5",
        "@babel/preset-react": "^7.0.0",
        "axios": "^0.18",
        "babel-loader": "^8.0.6",
        "bootstrap": "^4.1.0",
        "cross-env": "^5.1",
        "css-loader": "^3.0.0",
        "html-webpack-plugin": "^3.2.0",
        "jquery": "^3.2",
        "laravel-mix": "^4.0.7",
        "lodash": "^4.17.5",
        "popper.js": "^1.12",
        "react": "^16.8.6",
        "react-dom": "^16.8.6",
        "resolve-url-loader": "^2.3.1",
        "sass": "^1.15.2",
        "sass-loader": "^7.1.0",
        "style-loader": "^0.23.1",
        "webpack": "^4.35.0",
        "webpack-cli": "^3.3.5",
        "webpack-dev-server": "^3.7.2"
    },
    "dependencies": {
        "@babel/plugin-proposal-class-properties": "^7.4.4"
    }
}

在文件夹中使用时

package.json

{
  "main": "./Container.js"
}

错误

SyntaxError: C:\laravel\react-test\resources\js\components\Container\Container.js: Support for the experimental syntax 'classProperties' isn't currently enabled (14:12):

我想使用package.json，找不到解决方案

编辑我从组件中的json文件中删除了所有内容

{
}

问题仍然存在，直到我删除整个文件，我猜想当在组件中使用时，react发现仅与json有关的问题

如何使用package.json文件将主文件设置为在没有得到实验语法错误的情况下进行反应？
