eslint 在声明文件上抛出 import/no-unresolved 错误

Question

Eslint is throwing an import error: import/no-unresolved when a typescript declaration files is imported. I am using lerna for monorepo. Relevant declaration file import. Below imported file is app.d.ts file.

I can add "import/ignore": [".d.ts"] in the below config, which solves the error but I am looking for a solution other than this.

// types
import { Theme } from '@typings/app';

My.eslintrc.js config file:

module.exports = {
  parser: "@typescript-eslint/parser",
  extends: [
    "airbnb",
    "plugin:@typescript-eslint/recommended",
    "prettier",

Answer 1

You need more configs for typescript. the solution is as shown.

extends: [
    "airbnb",
    "plugin:import/typescript", // this is needed because airbnb uses eslint-plugin-import
    "plugin:@typescript-eslint/recommended",
    "prettier",
    "prettier/@typescript-eslint", // not related to this problem but it helps
    "prettier/react"
]

Answer 2

to improve your .eslintrc

...,
// parser: "@typescript-eslint/parser", -- not needed, "plugin:@typescript-eslint/recommended" has added
extends: [
  "airbnb",
  "plugin:import/typescript", // added
  "plugin:@typescript-eslint/recommended",
  "prettier",
  "prettier/@typescript-eslint" // added
  "prettier/react"
],
plugins: [
  // "react", -- not needed, airbnb has covered
  // "jsx-a11y", -- not needed, airbnb has covered
  // "react-hooks", -- not needed, airbnb has covered
  "sprinklr"
],
env: {
  browser: true,
  // node: true, -- not needed, airbnb has covered
  // es6: true, -- not needed, airbnb has covered
  amd: true // add define and require
},
globals: {
  // define: true, -- not needed, use amd env
  // require: true -- not needed, use amd env
},
...,
parserOptions: {
  // sourceType: "module", -- not needed, airbnb has covered
  // ecmaVersion: 6, -- not needed, airbnb has covered
  // ecmaFeatures: { -- not needed, airbnb has covered
  //   globalReturn: true, -- not needed, airbnb has covered
  //   jsx: true -- not needed, airbnb has covered
  // },
  allowImportExportEverywhere: true
},
...,
settings: {
  ...,
  // "react": { -- not needed, airbnb has covered
  //   version: "detect", -- not needed, airbnb has covered
  // },
  ...,
},

in addition, you may need to look what "plugin:import/typescript" has set here: https://github.com/benmosher/eslint-plugin-import/blob/master/config/typescript.js
