Есть ли проблема при использовании mobx в моем проекте, ошибка «Поддержка экспериментального синтаксиса« decorators-legacy »в настоящее время не включена»

Question

Я настроил мои package.json и babelrc, но у меня возникли ошибки при использовании декораторов.

Я использую «act16.8.1 »и« mobx5.9.4 ».

Мой код babelrc:

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

    ],
    "plugins": [
        "@babel/plugin-transform-runtime",
        "@babel/plugin-transform-object-assign",
        [
           "@babel/plugin-decorators-legacy",
            {
          "legacy": true
            }
        ],


    ]
}```
and my package.json

         {

         }
      ]
    ]
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ]
}

Я использовал его раньше, и он работал нормально, но после обновления реакции и mobx я получаю эту ошибку: «Поддержка экспериментального синтаксиса« decorators-legacy »в настоящее время не включена»
