尝试使Angular模板毛刺时出现ESLint错误

我有一个Angular 10应用程序,该应用程序设置了eslint和漂亮的脚本,到目前为止,对于lint Typescript文件来说,它运行良好。我现在也尝试将组件模板文件也放到following this doc中。

但是当我用eslint . --ext .js,.ts,.component.html --fix运行它时,我会不断得到

Error while loading rule '@typescript-eslint/dot-notation': You have used a rule which requires parserServices to be generated. You must therefore provide a value for the "parserOptions.project" property for @typescript-eslint/parser.

我的.eslintrc.js如下所示(请注意overrides部分的第二个块):

module.exports = {
  extends: [
    "plugin:@angular-eslint/recommended",
    // For spec files
    "plugin:jasmine/recommended",
    // AirBnB Styleguide rules
    "airbnb-typescript/base",
    // Settings for Prettier
    "prettier/@typescript-eslint",
    "plugin:prettier/recommended",
  ],
  plugins: [
    "prettier",
    "jasmine",
  ],
  rules: {
    "import/no-unresolved": "off",
    "@angular-eslint/component-selector": [
      "error", { type: "element", prefix: "icc", style: "kebab-case" }
    ],
    "@angular-eslint/directive-selector": [
      "error", { type: "attribute", prefix: "icc", style: "camelCase" }
    ],
    "import/extensions": "off",
    "@typescript-eslint/lines-between-class-members": "off",
    "lines-between-class-members": "off",
    "class-methods-use-this": "off",
    "import/prefer-default-export": "off",
    "prettier/prettier": ["error", {
      "endOfLine":"auto"
    }],
  },
  parser: "@typescript-eslint/parser",
  parserOptions: {
    project: "./tsconfig.app.json",
    ecmaVersion: 2020,
    sourceType: "module",
  },
  settings: {
    'import/resolver': {
      node: {
        extensions: ['.ts', '.js'],
        moduleDirectory: ['node_modules', 'src/app'],
      }
    }
  },
  overrides: [
    {
      files: ["*.component.ts"],
      parser: "@typescript-eslint/parser",
      parserOptions: {
        project: "./tsconfig.app.json",
        ecmaVersion: 2020,
        sourceType: "module",
      },
      plugins: ["@angular-eslint/template"],
      processor: "@angular-eslint/template/extract-inline-html",
    },
    {
      files: ["*.component.html"],
      parser: "@angular-eslint/template-parser",
      parserOptions: {
        project: "./tsconfig.app.json",
        ecmaVersion: 2020,
        sourceType: "module",
      },
      plugins: ["@angular-eslint/template"],
    },
    {
      files: ["src/**/*.spec.ts", "src/**/*.d.ts"],
      parser: "@typescript-eslint/parser",
      parserOptions: {
        project: "./tsconfig.spec.json",
        ecmaVersion: 2020,
        sourceType: "module",
      },
      // Jasmine rules
      extends: ["plugin:jasmine/recommended"],
      // Plugin to run Jasmine rules
      plugins: ["jasmine"],
      env: { jasmine: true },
    }
  ],
};

如您所见,我到处都指定parserOptions.project。我特别困惑,错误消息抱怨与@typescript-eslint/parser有关的东西,而不是应该用于模板的解析器。从覆盖部分中删除parserOptions块不会有什么区别。

我可以为它抱怨的所有规则设置"@typescript-eslint/dot-notation": "off",但显然这并不理想。有人可以指出我想念的东西吗?

更新:我已经按照Brad的建议关闭了所有类型识别规则。但是,我现在得到的错误是:

TypeError: Cannot read property 'length' of undefined
Occurred while linting /path/to/src/app/app.component.html:1
    at getUseStrictDirectives (/path/to/node_modules/eslint/lib/rules/strict.js:27:36)

但是我的app.component.html看起来像这样:

<div class="content-root">
  <router-outlet></router-outlet>
</div>

所以我又迷路了。

更新2 :我终于设法按照Brad在回答中建议的那样,通过关闭模板解析器的规则来使其工作。我的overrides工作块现在看起来像这样:

{
  files: ["*.component.html"],
  parser: "@angular-eslint/template-parser",
  rules: {
    "@typescript-eslint/dot-notation": "off",
    "@typescript-eslint/no-implied-eval": "off",
    "@typescript-eslint/no-throw-literal": "off",
    "strict": "off",
    "import/first": "off",
    "lines-around-directive": "off"
  },
  plugins: ["@angular-eslint/template"],
},

1 个答案:

答案 0 :(得分:1)

此处的配置将覆盖用于角度模板的解析器。这意味着您没有使用@typescript-eslint/parser来解析角度模板。

{
  files: ["*.component.html"],
  parser: "@angular-eslint/template-parser",
  parserOptions: {
    project: "./tsconfig.app.json",
    ecmaVersion: 2020,
    sourceType: "module",
  },
  plugins: ["@angular-eslint/template"],
},

这是有道理的,因为@typescript-eslint/parser无法理解角度模板。

然而,@angular-eslint/template-parser也没有提供用于类型识别的插入信息的必需的基础结构。

这就是为什么lint规则在您的文件上失败的原因。

您需要在用@angular-eslint/template-parser解析的文件上禁用所有类型识别棉绒规则。
