我在反应应用中使用swiper。在Internet Explorer 11中，它会弹出语法错误 （关于箭头功能，因为IE11不支持） 我添加了github存储库建议的代码，但它仍然无法在dom模块上获得语法错误。哪个使用功能箭头而不是转换成ES5。有人可以帮我纠正这个问题吗？
语法错误： Object.key（Methods）.forEach（（methodName）=＆gt; { WEBPACK_IMPORTED_MODULE_0_mod7_dist_dom7_modular ...}）;
.babelrc：
{
"presets": [
"es2015",
"react"
]
}
webpack文件部分：
test: /\.js$/,
exclude: /(node_modules|bower_components|node_modules\/(?!(dom7|ssr-window|swiper)\/).*)/,
use: {
loader: 'babel-loader',
options: {
presets: ['env'],
},
},
},
