使用 babel-plugin-proposal-decorators-legacy保存，提示更新后使用方式更改 报错信息： ``` 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' ``` 更换依赖为： ``` @babel/plugin-proposal-decorators ``` 并在package.json中配置plugin： ``` "plugins": [ [ "@babel/plugin-proposal-decorators", { "legacy": true } ] ] ```
