Question

当我安装Mobx并且Mobx反应时，出现以下错误。

./src/index.js
Error: The 'decorators' plugin requires a 'decoratorsBeforeExport' option, 
whose value must be a boolean. If you are migrating from Babylon/Babel 6 or 
want to use the old decorators proposal, you should use the 'decorators-legacy' 
plugin instead of 'decorators'.

现在，我弹出了依赖项，并安装了decorators-legacy作为插件。这就是我的package.json文件中的内容

"babel": {
"plugins": [
  "transform-decorators-legacy"
 ],
 "presets": [
  "react-app"
  ]
},
"devDependencies": {
"@babel/plugin-proposal-decorators": "^7.1.2",
"babel-plugin-transform-decorators-legacy": "^1.3.5"
}

任何帮助将不胜感激，因为这在最近几天一直使我发疯。

在Tholle撰写文章时，链接非常有帮助。我的配置在我的package.json中。

"babel": {
"presets": ["@babel/preset-env","react-app"],

"plugins": [
    ["@babel/plugin-proposal-decorators", { "legacy": true }],
    ["@babel/plugin-proposal-class-properties", { "loose": true }]
  ]
},
"devDependencies": {
"@babel/plugin-proposal-decorators": "^7.1.2",
"babel-plugin-transform-decorators-legacy": "^1.3.5"
}

尝试安装MobX，但在启动服务器时出现装饰器错误
