首页 > 解决方案 > 让 Prettier 在使用 eslint 时理解 TS "as" 运算符

问题描述

我正在尝试将 Prettier 与 ESLint 一起用于 TS。但它失败并出现错误

SyntaxError: Unexpected identifier, expected the token `)` (17:55)

与在线

const initialState = !process.env.IS_SERVER ? (window as any).__INITIAL_DATA__ : {};

此错误与 prettier 有关。

我已经为 ES 安装了所有推荐的插件来使用 prettier 和 TS。ES 配置在这里(.eslingrc.js):

module.exports = {
  parser: "@typescript-eslint/parser", // Specifies the ESLint parser
  extends: [
    "plugin:react/recommended", // Uses the recommended rules from @eslint-plugin-react
    "plugin:@typescript-eslint/recommended", // Uses the recommended rules from the @typescript-eslint/eslint-plugin
    "prettier/@typescript-eslint", // Uses eslint-config-prettier to disable ESLint rules from @typescript-eslint/eslint-plugin that would conflict with prettier
    "plugin:prettier/recommended" // Enables eslint-plugin-prettier and eslint-config-prettier. This will display prettier errors as ESLint errors. Make sure this is always the last configuration in the extends array.
  ],
  parserOptions: {
    ecmaVersion: 2018, // Allows for the parsing of modern ECMAScript features
    sourceType: "module", // Allows for the use of imports
    ecmaFeatures: {
      jsx: true // Allows for the parsing of JSX
    }
  },
  rules: {
    // Place to specify ESLint rules. Can be used to overwrite rules specified from the extended configs
    // e.g. "@typescript-eslint/explicit-function-return-type": "off",
  },
  settings: {
    react: {
      version: "detect" // Tells eslint-plugin-react to automatically detect the version of React to use
    }
  }
};

我使用 IDE WebStorem。类型的运算符扩展也因 prittier 而失败。

为什么不理解“as”运算符?请帮帮我。

解决方案


在 .eslintrc 中将解析器添加为“typescript”。

rules: {
  "prettier/prettier": ["error", {"singleQuote": true, "parser": "typescript", "endOfLine": "auto"}]
}

这为我修好了。
