Eslint 不显示警告 - React

如何解决Eslint 不显示警告 - React

在我的新项目中，ESLint 没有像以前那样输出警告，我使用的是 VSCode。如果我的代码中某处有一个 unsed var，它就不再在终端输出中显示警告。仅在问题选项卡中。

这是我的 eslint 配置文件：

.eslintrc.json

{
  "env": {
      "browser": true,"es6": true
  },"extends": [
      "plugin:react/recommended","airbnb-typescript","plugin:@typescript-eslint/recommended","plugin:@typescript-eslint/eslint-recommended","prettier/@typescript-eslint","plugin:prettier/recommended"
  ],"globals": {
      "Atomics": "readonly","SharedArrayBuffer": "readonly"
  },"parser": "@typescript-eslint/parser","parserOptions": {
      "ecmaFeatures": {
          "jsx": true
      },"ecmaVersion": 2018,"sourceType": "module","project": "./tsconfig.json"
  },"plugins": [
      "react","react-hooks","@typescript-eslint","prettier"
  ],"rules": {
    "prettier/prettier": "error","react-hooks/rules-of-hooks":"error","react-hooks/exhaustive-deps": "warn","camelcase": "off","@typescript-eslint/camelcase": "off","react/jsx-filename-extension": [1,{"extensions": [".tsx"]}],"import/prefer-default-export": "off","react/jsx-one-expression-per-line": "off","react/jsx-props-no-spreading": "off","react/prop-types": "off","no-unused-expressions": "off","@typescript-eslint/no-unused-vars": "error","@typescript-eslint/explicit-function-return-type": [
      "error",{
        "allowExpressions": true
      }
    ],"import/extensions": [
      "error","ignorePackages",{
        "ts": "never","tsx": "never"
      }
    ],"semi":"off"
  },"settings": {
    "import/resolver": {
      "typescript": {}
    }
  }
}

这是我的 package.json devDependencies：

package.json

  "dependencies": {
    ...,"react": "^17.0.1","react-dom": "^17.0.1","react-scripts": "^4.0.2"
  }
  "devDependencies": {
    "@types/react-router-dom": "^5.1.7","@types/styled-components": "^5.1.7","@typescript-eslint/eslint-plugin": "^4.14.2","@typescript-eslint/parser": "^4.14.2","eslint": "^7.19.0","eslint-config-airbnb": "^18.2.1","eslint-config-airbnb-typescript": "^12.3.1","eslint-config-prettier": "^7.2.0","eslint-import-resolver-typescript": "^2.3.0","eslint-plugin-import": "^2.22.1","eslint-plugin-jsx-a11y": "^6.4.1","eslint-plugin-prettier": "^3.3.1","eslint-plugin-react": "^7.22.0","eslint-plugin-react-hooks": "^4.2.0","husky": "^5.0.8","prettier": "^2.2.1","prettier-eslint-cli": "^5.0.0","typescript": "^4.1.3"
  }

解决方法

我遇到了同样的问题，对我来说是在我的 package.json 中缺少这个 esLint 配置：

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

可能是误删了。
