尝试对Angular模板进行代码检查时出现ESLint错误。
尝试对Angular模板进行代码检查时出现ESLint错误。
我有一个使用eslint和prettier设置的Angular 10应用程序,目前在对TypeScript文件进行linting方面运行良好。我现在还尝试对我的组件模板文件进行linting,遵循此文档。但是,当我使用`eslint . --ext .js,.ts,.component.html --fix`运行时,我一直得到以下错误:`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`文件如下(请注意`overrides`部分中的第二个块):
module.exports = { extends: [ "plugin:@angular-eslint/recommended", "plugin:jasmine/recommended", "airbnb-typescript/base", "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", }, extends: ["plugin:jasmine/recommended"], plugins: ["jasmine"], env: { jasmine: true }, } ], };
正如您所看到的,我在每个地方都指定了`parserOptions.project`。我特别困惑的是错误消息抱怨与`@typescript-eslint/parser`相关的问题,而这不是应该用于模板的解析器。从`overrides`部分中删除`parserOptions`块并没有产生任何区别。
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。有人能告诉我我漏掉了什么吗?
更新:我像Brad建议的那样关闭了所有的type-aware规则。然而,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`只是这样的:
所以我又一次迷失了方向。
更新2:我终于成功了,根据Brad在他的答案中建议的,逐个关闭了模板解析器的规则。我的工作`overrides`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"], }
ESLint在尝试对Angular模板进行lint时出现错误的原因是由于配置文件中覆盖了用于解析Angular模板的解析器。这意味着你没有使用-eslint/parser
来解析你的Angular模板。
原因是-eslint/parser
无法理解Angular模板。然而,-eslint/template-parser
也没有提供进行类型感知linting所需的基础设施。
因此,lint规则在你的文件上失败了。你需要在使用-eslint/template-parser
解析的文件上禁用所有类型感知lint规则。
关于angular-eslint,我对它了解不多,但我认为项目的工作方式意味着你必须在Angular模板文件上禁用所有标准的eslint lint规则。
你是对的,我现在已经解决了这个问题,并相应地更新了我的答案。
