推荐答案

我正在使用 plugin-proposal-class-propterties ，它可以正常工作，这是我的JSON配置文件 .babelrc

I am using plugin-proposal-class-propterties and it works, here is my JSON configuration file .babelrc

{
  "presets": ["@babel/preset-env"],
  "plugins": [
    [
      "@babel/plugin-proposal-class-properties",
      {"loose": true}
    ]
  ]
}
