webpack 中的 eslint 导入：无法解析模块路径

Question

使用 eslint-import-resolver-webpack 我试图通过引用 "shortcut"（例如 components/Counter）让 eslint 知道我想要导入文件。

在下面的示例中，webpack (v2.2.0-rc.3) 构建良好，但测试失败，因为它是 "Unable to resolve path to module 'components/Counter'"。我在导入 'components/Counter/reducer' 时也遇到此错误，因此它不限于索引。

运行 npm run lint 和我的 IDE (IntelliJ) 都给出相同的错误。

按照文档，我设置了以下配置：

（部分）文件结构：

project-root/
  app/
    components/
      Counter/
        index.js
        reducer.js
    app.js
 internals/ 
   config/
      .eslintrc
      webpack.test.js
  package.json

文件：project-root/app/app.js

import Counter from 'components/Counter'
// etc...

摘录自：project-root/package.json

...
"lint": "npm run lint:eslint -- . ",
"lint:eslint": "eslint -c internals/config/.eslintrc --fix --ignore-path .gitignore --ignore-pattern internals"
...

并且：project-root/internals/config/webpack.test.js:

const webpack = require('webpack')

module.exports = {
  devtool: 'inline-source-map',

  module: {
    loaders: [
      { test: /\.json$/, loader: 'json-loader' },

      { test: /\.css$/, loader: 'null-loader' },

      { test: /\.js$/,
        loader: 'babel',
        exclude: [/node_modules/],
      },

      { test: /\.jpe?g$|\.gif$|\.png$|\.svg$/i,
        loader: 'null-loader',
      },
    ],
  },

  plugins: [
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: JSON.stringify(process.env.NODE_ENV),
      },
    }),
  ],

  resolve: {
    modules: [
      'app',
      'node_modules',
    ],
  },
}

注意：我也试过指向一个只导出解析对象的文件。同样的事情：

module.exports = {
  resolve: {
    modules: [
      'app',
      'node_modules',
    ],
  }
}

看来我的依赖项需要更新...

彻底的 linting 过程需要相当多的插件、配置等..

--编辑--

这是我的项目依赖项的摘录。这里可能有一些不需要的包，我只删除了我确定不会有影响的包。

请注意，front-end 陆地在 6 档时像猎豹一样移动，因此版本可能很快就会过时。无论如何，截至目前（2017 年 2 月），这是一个有效的配置。

我相信您在 .eslintrc,js 中错过了一些配置：

    'import/resolver': {
...,
      webpack: {
        config: {
          resolve: {
            alias: {
              // map your aliases here eg:
              components: '/src/components',
            },
          },
        },
      },
    },
