Question

我想在cmd中使用eslint来检查ts文件，但是无法获取我在IDE中得到的错误信息。

我在eslintrc.js中设置了@ typescript-eslint / parser。当我做错了一些命令时，在cmd中运行的eslint给了我一些TS错误。但是没有发现其他错误。

我有一个包含以下代码的ts文件：

interface Item {
  name: string;
  age: number;
}
const config: Array<Item> = [{
  name: 'foo',
}]

所以，我在IDE中出现了一些错误：

Property 'age' is missing in type '{ name: string; age: number }' but required in type 'Item'.ts(2741)

那是正确的。我需要此错误信息。

但是当我在cmd中运行eslint

eslint fileName.ts  or  eslint --ext .ts fileName.ts

cmd eslint在此文件中不返回任何内容或其他警告/错误。

此处为eslintrc


module.exports = {
  "extends": ["xxx"],
  "globals": {
    "__SERVER_ENV__": true,
  },
  "rules": {
    "react/jsx-filename-extension": 0,

      "ignoreRestSiblings": true
    }],
  },

  "settings": {
    "react": {
      "createClass": "createReactClass", // Regex for Component Factory to use,
      // default to "createReactClass"
      "pragma": "React",  // Pragma to use, default to "React"
      "version": "detect", // React version. "detect" automatically picks the version you have installed.
      // You can also use `16.0`, `16.3`, etc, if you want to override the detected value.

    },

    "import/resolver": {
      // use <root>/tsconfig.json
      "typescript": {
        // always try to resolve types under `<roo/>@types` directory even it doesn't contain any source code, like`@types/unist`
        "alwaysTryTypes": true,
        "directory": "./",
      },
    },
  },

    "sourceType": "module",
    "ecmaFeatures": {
      "modules": true,
    },
  },
  "plugins": ["@typescript-eslint", "import"],
};

和tsconfig.json

{
  "compilerOptions": {
    "experimentalDecorators": true,
    "noImplicitAny": true,
    "module": "commonjs",
    "lib": ["es6","dom","es2017"],
    "target": "es5",
    "jsx": "react",
    "types":["react"],
    "outDir": "/output",
    "baseUrl": ".",
    "paths": {
        "src/*": ["./src/*"]
    },
    "allowSyntheticDefaultImports": true,
    "sourceMap": true
  },
  "awesomeTypescriptLoaderOptions": {
    "useWebpackText": true,
    "useTranspileModule": true,
    "doTypeCheck": true,
    "forkChecker": true
  },
  "include": [
    ".d.ts",
    "./src/**/*"
  ]
}

我希望通过cmd获取全部错误信息。我该怎么办？

似乎eslint设计不会执行您的Typescript类型检查。我只是使用tsc在本地运行构建命令，以通知该“类型缺失的属性”错误消息，并在构建失败时进行修复。

这非常不方便，因为每次构建尝试只会收到一个错误的警报。如果有人有更好的解决方案，我将不胜感激。

cmd eslint找不到IDE发现的ts错误
