装饰器插件当.version为“2018-09”或未指定时，需要“decoratorsBeforeExport”选项，其值必须是布尔值

Question

我得到以下信息Babel error

当 .version 为“2018-09”或未指定时，装饰器插件需要“decoratorsBeforeExport”选项，其值必须是布尔值。..../node_modules/@babel/plugin-proposal-decorators/lib/index.js$inerhits

这是我的babel.config.js

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  plugins: [
    'react-native-reanimated/plugin',
    [
        "@babel/plugin-proposal-decorators", 
        { 
            "legacy": true, 
            "decoratorsBeforeExport": false // I tried this with true as well -> no luck either
        }
    ]
 ]
};

这是我正在使用的版本

    ....
"dependencies": {
    "react": "17.0.2",
    "react-native": "0.66.4"
    ...

"devDependencies": {
    "@babel/core": "^7.12.9",
    "@babel/plugin-proposal-decorators": "^7.17.9",
    "@babel/runtime": "^7.12.5",
    "@react-native-community/eslint-config": "^2.0.0",
    "babel-jest": "^26.6.3",
    "eslint": "7.14.0",
    "jest": "^26.6.3",

尝试这个。这对我有用

module.exports = {
    presets: [['@babel/preset-env', { targets: { node: 'current' } }]],
    plugins: [['@babel/plugin-proposal-decorators', { legacy: true }]]

};
