redux connect的装饰器问题

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’.
解决办法：

cnpm install babel-plugin-transform-decorators-legacy  --save-dev
cnpm install  @babel/plugin-proposal-decorators --save-dev
然后npm run eject  弹出个性化配置

修改babel部分，添加代码

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

就ok了
如果用的是vscode有提示报错 “experimentalDecorators”
解决办法：
点击Visual Studio Code左下角的配置按钮(或者文件>首选项>配置)，打开用户设置窗口，在搜索框内输入“experimentalDecorators”

"javascript.implicitProjectConfig.experimentalDecorators": false  
// 把false改成true 重启编辑器就可以了
