Question

一切似乎都很好：http://d.pr/i/1aZxR 以下配置。

然而，当我运行代码时，我得到以下错误（通过webpack-dev-server）：

Uncaught TypeError: __webpack_require__(...) is not a function(anonymous function) @ login.js:4__webpack_require__ @ bootstrap 38790ff45722f55eb700?6a08:50(anonymous function) @ bootstrap.js:2363__webpack_require__ @ bootstrap 38790ff45722f55eb700?6a08:50(anonymous function) @ app.38790ff45722f55eb700.js:29__webpack_require__ @ bootstrap 38790ff45722f55eb700?6a08:50webpackJsonpCallback @ bootstrap 38790ff45722f55eb700?6a08:21(anonymous function) @ app.38790ff45722f55eb700.js:1

我认为babel在某种程度上干扰了__webpack_require__，但我不确定。我确实尝试过使用不同的转换/插件，但我找不到解决方案。

.babelrc：

{
  "plugins":[
    "transform-runtime",
    "transform-node-env-inline"
  ],
  "presets":[
    "stage-0",
    "es2015"
  ]
}

这是我的webpack.config.js：

Answer 1

我想添加另一个可能会出现此错误的原因：

我做了以下事情：

import mapActions from 'vuex'

而不是：

import { mapActions } from 'vuex'

前者导入整个vuex导出，这是一个对象。添加对象解构修复了问题。

Answer 2

我有同样的错误。处理es6模块时，您应该使用 require（...）。default

例如：

const angular = require('angular');
const ngModule = angular.module('app', []);
require('./directives').default(ngModule);
// or
var kgdir = require('./directives').default;
kgdir(ngModule);

但是，babel-plugin-add-module-exports也应该有用。

您可以查看此页面：github webpack issues 1685

Answer 3

我认为建议的从需要切换到导入的解决方案是不正确的。导入需要发生在文件的顶部，因此您不能让生产版本省略devtools。你想要一个条件要求。

我认为babel-plugin-add-module-exports解决了这个问题。看一下这个react-redux-starter-kit，看看它在项目中是如何使用的。

Answer 4

在我的webpack-dev-server条目文件中更新到Babel 6后，我遇到了类似的问题。正如@Serhey在评论中所提到的，我通过从需要转换为导入来解决了我的问题，即require('./devTools)(store);到import devTools from './devTools'; devTools(store);

Answer 5

我有同样的问题。解决方案是从require语句切换，例如

let fs = require("fs");

通过

导入

import * as fs from 'fs';

您还可以通过webpack配置中的externals数组公开所有Node模块。由于它们是通过Webpack外部提供的，因此不需要它们，而是将它们与导入一起使用。

module.exports = {
   "externals": {
      "electron": "require('electron')",
      "child_process": "require('child_process')",
      "fs": "require('fs')",
      "path": "require('path')",
      ...
   }
}

您可以在my article中了解有关此问题的更多信息。

Answer 6

我通过在webpack.config中添加一个缺少的加载器解决了类似的问题。不知道为什么这会解决这个问题，但你可能想看看你是否也错过了一个装载机。

（只是要清楚 - 我最初发现问题是在我降级库时导致问题导致早期版本的问题.Webpack错误消息说json加载器丢失了，所以我将以下内容添加到我的配置，然后能够回到最新版本：

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

）

Answer 7

我的webpack遇到了这个问题，因为我正在同时为Web和节点构建项目，并且在isomorphic-unfetch中都使用entry。

我通过将isomorphic-unfetch替换为适当的抓取方式来修复了该问题：unfetch（针对Web）和node-fetch（针对Node.js）

webpack.config.js

module.exports = [
  {
    entry: ['unfetch', 'regenerator-runtime/runtime', './lib/app.js'],
    ...
  },
  {
    entry: ['node-fetch', 'regenerator-runtime/runtime', './lib/app.js'],
    target: 'node',
    ...
  },
];

Answer 8

我的情况与上述@William给出的答案相反。在其中包含{} import mapActions from 'vuex'帮助了我。为：

import { mapActions } from 'vuex'

使用babel 6时，`__webpack_require __（...）不是函数`
