eslint 抱怨解决路径

Question

I keep receiving the eslint error import/no-unresolved and am unsure as to how I fix it. I know this is related to babel, but I'm not sure how to get babel and eslint to play nice.

My babel.config.js file:

module.exports = {
  presets: [['@babel/preset-env', { targets: { node: 'current' } }], '@babel/preset-react'],
  plugins: [
    'babel-plugin-macros',
    '@babel/plugin-syntax-dynamic-import',
    '@babel/plugin-transform-destructuring',
    [
      '@babel/plugin-proposal-class-properties',
      {
        loose: true,
      },
    ],
    [
      '@babel/plugin-proposal-object-rest-spread',
      {
        useBuiltIns: true,
      },
    ],
    [
      '@babel/plugin-transform-runtime',
      {
        helpers: false,
        regenerator: true,
      },
    ],
    [
      '@babel/plugin-transform-regenerator',
      {
        async: false,
      },
    ],
  ],
};

… and my .eslintrc.js file

module.exports = {
  parser: 'babel-eslint',
  extends: 'airbnb',
  env: {
    browser: true,
    node: true,
    jest: true,
    es6: true,
  },
  plugins: ['react', 'jsx-a11y'],
  parserOptions: {

    semi: ['error', 'always'],
  },
  settings: {
    'import/resolver': {
      webpack: {
        config: 'config/webpack/development.js',
      },
    },
  },
};

The issue occurs for every type of import:

Any suggestions?

EDIT

I've created a repository using the same eslint setup as I'm using in this project. It's showing the same error I'm seeing.

You'll have to at the very least update your eslint config to say you want ES2018 (or newer) support, since you're validating modern JS with module imports:

module.exports = {
  ...
  parserOptions: {
    ecmaVersion: 2018,
    sourceType: 'module',
    ecmaFeatures: {
      jsx: true,
    },
  },
  ...
};

Because from https://eslint.org/docs/user-guide/configuring#specifying-parser-options we know that ecmaVersion: 6 corresponds to asking ESLint to validate your code as ES2015, which predates ES modules, and so will correctly flag any import ... from "..." statement as an error.

I tried your github repo with a heavily reduced ESlint config:

module.exports = {
  parser: 'babel-eslint',
  extends: 'airbnb',
  env: {
    browser: true,
    node: true,
    jest: true,
    es6: true
  },
  plugins: ['react'],
  parserOptions: {
    ecmaVersion: 2018,
    sourceType: 'module',
    ecmaFeatures: {
      jsx: true,
    },
  },
  rules: {
    'no-unused-vars': 0
  }
};

And that works just fine, so: start building it back up until it breaks, so you have a better idea of what really needs addressing.
