我有这个 Webpack 配置:
const path = require('path');
module.exports = {
entry: ['babel-polyfill', './lib/index.js'],
output: {
path: path.resolve(__dirname + '/dist'),
filename: 'suman.js'
},
module: {
loaders: [
{
test: /\.js$/,
loader: 'babel-loader',
options: {
presets: ['latest'],
plugins: ['transform-runtime']
}
}
]
},
node: {
assert: 'empty',
buffer: 'mock',
child_process: 'empty',
cluster: 'empty',
console: 'mock',
constants: 'empty',
crypto: 'empty',
dgram: 'empty',
dns: 'mock',
domain: 'empty',
events: 'empty',
fs: 'empty',
http: 'empty',
https: 'empty',
module: 'empty',
net: 'mock',
os: 'empty',
path: 'empty',
process: 'mock',
punycode: 'mock',
querystring: 'empty',
readline: 'empty',
repl: 'empty',
stream: 'empty',
string_decoder: 'empty',
timers: 'empty',
tls: 'mock',
tty: 'mock',
url: 'empty',
util: 'empty',
v8: 'mock',
vm: 'empty',
zlib: 'empty',
}
};
我在命令行运行 $webpack 并得到一个输出文件,我将文件加载到浏览器中,如下所示:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Suman tests</title>
<script src="../../../dist/suman.js"></script>
</head>
<body>
</body>
</html>
如果我在浏览器中加载这个 html 文件,我会得到:
suman.js:48039 Uncaught TypeError: $export is not a function

我在 Github 上查看了一堆问题,但似乎都没有解决问题。有谁知道可能出了什么问题?
我使用的是 Webpack 版本 2.3.3。
附带说明 - 我在哪里可以找到一些适用于 Node.js / NPM 模块的 polyfill?
$export
似乎是 Webpack 生成的一个函数,下面是我的输出文件中出现的一些函数:
var global = __webpack_require__(10),
core = __webpack_require__(58),
hide = __webpack_require__(33),
redefine = __webpack_require__(34),
ctx = __webpack_require__(59),
PROTOTYPE = 'prototype';
var $export = function $export(type, name, source) {
var IS_FORCED = type & $export.F,
IS_GLOBAL = type & $export.G,
IS_STATIC = type & $export.S,
IS_PROTO = type & $export.P,
IS_BIND = type & $export.B,
target = IS_GLOBAL ? global : IS_STATIC ? global[name] || (global[name] = {}) : (global[name] || {})[PROTOTYPE],
exports = IS_GLOBAL ? core : core[name] || (core[name] = {}),
expProto = exports[PROTOTYPE] || (exports[PROTOTYPE] = {}),
key,
own,
out,
exp;
if (IS_GLOBAL) source = name;
for (key in source) {
