字段“browser”不包含有效的别名配置

我已经开始使用webpack2(准确地说，v2.3.2)，在重新创建我的配置后，我一直遇到一个问题，我似乎无法解决我得到(提前为丑陋的转储道歉):

ERROR in ./src/main.js
Module not found: Error: Can't resolve 'components/DoISuportIt' in '[absolute path to my repo]/src'

[[absolute path to my repo]/src/components/DoISuportIt]
[[absolute path to my repo]/src/components/DoISuportIt.js]
[[absolute path to my repo]/src/components/DoISuportIt.jsx]

package.json

{
  "version": "1.0.0",
  "main": "./src/main.js",
  "scripts": {
    "build": "webpack --progress --display-error-details"
  },
  "devDependencies": {
    ...
  },
  "dependencies": {
    ...
  }
}

关于它所抱怨的浏览器字段，我能够找到的文档是:package-browser-field-spec。也有webpack文档，但它似乎默认开启:aliasFields: ["browser"]。我尝试在我的包中添加一个浏览器字段。Json，但这似乎没有任何好处。

webpack.config.js

import path from 'path';
const source = path.resolve(__dirname, 'src');

export default {
  context: __dirname,
  entry: './src/main.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: '[name].js',
  },
  resolve: {
    alias: {
      components: path.resolve(__dirname, 'src/components'),
    },
    extensions: ['.js', '.jsx'],
  },
  module: {
    rules: [
      {
        test: /\.(js|jsx)$/,
        include: source,
        use: {
          loader: 'babel-loader',
          query: {
            cacheDirectory: true,
          },
        },
      },
      {
        test: /\.css$/,
        include: source,
        use: [
          { loader: 'style-loader' },
          {
            loader: 'css-loader',
            query: {
              importLoader: 1,
              localIdentName: '[path]___[name]__[local]___[hash:base64:5]',
              modules: true,
            },
          },
        ],
      },
    ],
  },
};

src / main.js

import DoISuportIt from 'components/DoISuportIt';

src /组件/ DoISuportIt / index.jsx

export default function() { ... }

为完整起见，.babelrc

{
  "presets": [
    "latest",
    "react"
  ],
  "plugins": [
    "react-css-modules"
  ],
  "env": {
    "production": {
      "compact": true,
      "comments": false,
      "minified": true
    }
  },
  "sourceMaps": true
}

我做错了什么/遗漏了什么?

当前回答

在我的例子中，模块下的输入字段丢失了。在webpack.config.js中导出，导致此问题。

其他回答

只是为了记录，因为我有类似的问题，也许这个答案会帮助别人:在我的情况下，我使用的是使用.js文件的库，我没有这样的扩展在webpack解析扩展。添加适当的扩展固定问题:

module.exports = {
(...)
  resolve: {
    extensions: ['.ts', '.js'],
  }
}

Webpack出现了一个问题，就是不能解决导入的问题——谈论可怕的错误消息:(

// I Had to change:
import DoISuportIt from 'components/DoISuportIt';

// to (notice the missing `./`)
import DoISuportIt from './components/DoISuportIt';

在我的情况下，我导入库文件如下:

import { MyFile } from "my-library/public-api";

在我从导入中删除了public-api之后，一切都正常工作:

import { MyFile } from "my-library";

MyFile在库中的public-api文件中导出。

我正在使用“@google-cloud/translate”:“^5.1.4”，并在这个问题上苦苦挣扎，直到我尝试了这个:

我打开google-gax\build\src\operationsClient.js文件并更改

const configData = require('./operations_client_config');

const configData = require('./operations_client_config.json');

这就解决了错误

ERROR in ./node_modules/google-gax/build/src/operationsClient.js Module not found: Error: Can't resolve './operations_client_config' in 'C:\..\Projects\qaymni\node_modules\google-gax\build\src' resolve './operations_client_config' ......

我希望它能帮助到一些人
