尝试使Angular模板毛刺时出现ESLint错误

如何解决尝试使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",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"],parserOptions: {
        project: "./tsconfig.app.json",plugins: ["@angular-eslint/template"],processor: "@angular-eslint/template/extract-inline-html",{
      files: ["*.component.html"],parser: "@angular-eslint/template-parser",{
      files: ["src/**/*.spec.ts","src/**/*.d.ts"],parserOptions: {
        project: "./tsconfig.spec.json",// 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"],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"
  },

解决方法

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。
