javascript - React Typescript 类型转换问题 - 解析错误 : Missing Semicolon

Question

我有这行简单的代码:

const target = e.target as HTMLLIElement;

我收到了这个错误:

  Line 18:28:  Parsing error: Missing semicolon
> 18 |     const target = e.target as HTMLLIElement;
     |                            ^

我查看了许多与我的问题相似的不同帖子，但没有一个与我的问题完全匹配，或者他们的解决方案与我的项目并不真正相关。例如，有些遇到了 eslint 问题，但我没有安装 eslint 包。这是我的 package.json文件:

{
  "name": "ally-autobot",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@craco/craco": "^6.1.1",
    "@reduxjs/toolkit": "^1.5.1",
    "@tailwindcss/postcss7-compat": "^2.1.0",
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.3.2",
    "@testing-library/user-event": "^7.1.2",
    "@types/jest": "^24.0.0",
    "@types/lodash": "^4.14.168",

    "lint": "^0.7.0",

    "postcss": "^7",
    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "react-firebase-hooks": "^3.0.4",
    "react-redux": "^7.2.0",
    "react-router": "^5.2.0",
    "react-router-dom": "^5.2.0",
    "react-scripts": "4.0.3",
    "redux-persist": "^6.0.0",
    "source-map-loader": "^2.0.1",
    "tailwindcss": "npm:@tailwindcss/postcss7-compat",
    "typescript": "~4.1.5"
  },
  "scripts": {
    "start": "craco start",
    "build": "craco build",
    "test": "craco test",
    "eject": "react-scripts eject"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

这是我的 tsconfig.json文件:

{
  "compilerOptions": {
    "sourceMap": true,
    "incremental": true,
    "target": "es5",
    "module": "esnext",
    "strict": true,
    "noImplicitAny": true,
    "strictNullChecks": true,
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true,
    "lib": [
      "dom",
      "dom.iterable",
      "esnext"
    ],
    "allowJs": true,
    "skipLibCheck": true,
    "allowSyntheticDefaultImports": true,
    "noFallthroughCasesInSwitch": true,
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
    "jsx": "react"
  },
  "include": [
    "src"
  ]
}

我也尝试过使用尖括号方法，但这不起作用，因为我在 tsx 文件中。我尝试将 noImplicitAny 设置为 false。我尝试将分号添加到与此错误相同的文件中的所有表达式中。
关于如何解决这个问题的任何想法？

Answer 1

应该是 eslint 的错误。
将 eslintConfig 添加到 package.json可以解决你的问题。
以下设置是 create-react-app 中的默认 eslintConfig

"dependencies": {
...
},
"eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
},
