如何启用对实验语法“ decorators-legacy”的支持？

Question

每当我运行./gradlew assembleRelease，它就会随之出现

我尝试运行npm i --save-dev @babel/plugin-proposal-class-properties @babel/plugin-proposal-decorators和./gradlew --stop，但都没有用。

我还在.babelrc文件中添加了["@babel/plugin-proposal-class-properties", { "loose": true}]，但没有任何改变。

我的.babelrc：

{
  "presets": ["module:metro-react-native-babel-preset"],
  "env": {
    "production": {
      "plugins": [
        "transform-remove-console", 
        ["@babel/plugin-proposal-decorators", { "legacy": true}],
        ["@babel/plugin-proposal-class-properties", { "loose": true}]
      ]
    },
    "development": {
      "plugins": [
        "transform-remove-console", 
        ["@babel/plugin-proposal-decorators", { "legacy": true}],
        ["@babel/plugin-proposal-class-properties", { "loose": true}]
      ]
    }
  }
}

我的package.json：
