我正在使用babel-preset-env版本 - 1.6.1为我的反应应用程序,我在IE上收到错误: - 对象不支持属性或方法'assign'

这是我的.babelrc: -

{
"presets": [
    "react",
    [
        "env",
        {
            "targets": {
                "browsers": [
                    "last 1 versions",
                    "ie >= 11"
                ]
            },
            "debug": true,
            "modules": "commonjs"
        }
    ]
],
"env": {
    "test": {
        "presets": [
            [
                "babel-preset-env",
                "react"

        "plugins": [

            "transform-class-properties",
            "transform-runtime",
            "babel-plugin-dynamic-import-node",
            "array-includes",
            "url-search-params-polyfill",
            "transform-object-assign"
        ]
    }
},
"plugins": [
    "transform-object-rest-spread",
    "transform-class-properties",
    "syntax-dynamic-import",
    "transform-runtime",
    "array-includes",
    "url-search-params-polyfill",
    "transform-object-assign"
]

}

我试过这些polyfills: -

我正在使用语法: -
