我按照介绍中的"experimentalDecorators": true说明做了，我在 tsconfig.json 中添加了“compilerOptions”。但是，错误仍然存​​在。

这是为什么？我该如何解决？

这是我的 package.json

{
  "name": "frontend",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.12.0",
    "@testing-library/react": "^11.2.6",
    "@testing-library/user-event": "^12.8.3",
    "@types/jest": "^26.0.23",
    "@types/node": "^15.6.0",
    "@types/react": "^17.0.6",
    "@types/react-dom": "^17.0.5",
    "axios": "^0.21.1",
    "framer-motion": "^4.1.17",
    "history": "^5.0.0",
    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "react-loader-spinner": "^4.0.0",
    "react-promise-tracker": "^2.1.0",
    "react-redux": "^7.2.4",
    "react-router": "^5.2.0",
    "react-router-dom": "^5.2.0",
    "react-scripts": "^4.0.3",
    "redux": "^4.1.0",
    "typescript": "^4.2.4",
    "web-vitals": "^1.1.2"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "devDependencies": {
    "@babel/core": "^7.14.0",
    "@babel/preset-env": "^7.14.1",
    "@babel/preset-react": "^7.13.13",
    "autoprefixer": "^9.8.6",
    "babel-loader": "^8.1.0",
    "file-loader": "^6.1.1",
    "url-loader": "^4.1.1"
  }
}

这是我的 tsconfig.json

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

这就是我所有的配置文件。我并没有真正手动触及任何一个配置文件中的任何内容，它们都是预先生成的——"experimentalDecorators": true当然新添加的行除外。
