Javascript 支持实验语法'；装饰者遗产'；isn'；t当前已启用（创建react应用程序）

正如中所述，我在tsconfig.json中的“编译器选项”中添加了

“experimentalDecorators”：true

。但是，错误仍然存在

为什么呢？我怎样才能修好它

这是我的package.json

这是我的tsconfig.json

{
  "compilerOptions": {
    "module": "commonjs",
    "target": "es5",
    "sourceMap": true,
    "strict": true,
    "experimentalDecorators": true
  },
  "exclude": [
    "node_modules"
  ]
}

这是我所有的配置文件。我并没有真正手动处理这两个配置文件中的任何内容，它们都是预生成的——除了新添加的

“experimentalDecorators”：当然是
