配置`@ babel / runtime-corejs3`以排除es.date.now

Question

我正试图防止@babel/preset-env +@babel/plugin-transform-runtime+ @babel/runtime-corejs3替换Date.now()，以便解决an issue preventing @sinonjs/fake-timers from working correctly。

根据@sinonjs/fake-timers，应该有一种方法可以防止它应用documentation for core-js填充，但我不知道如何应用此配置。

示例

es.date.now

index.js

通天塔]

import FakeTimers from '@sinonjs/fake-timers'

FakeTimers.install()

console.log(new Date().getTime())
console.log(Date.now())

注意转移输出的最后一行—我希望它是

$(npm bin)/babel index.js
...
console.log(new Date().getTime());
console.log((0, _now["default"])());

查看console.log(Date.now());的文档后，我觉得@babel/preset-env是我想要的，但我无法使它正常工作：

the exclude option
上面给我一个错误：

exclude
我如何配置Babel在移植期间排除module.exports = {
  presets: [
    ['@babel/preset-env', { exclude: ['es.date.now'] }]
  ],
  plugins: [
    ['@babel/plugin-transform-runtime', { corejs: 3 }]
  ]
}
 polyfill？

请参见babel.config.js。 plugin-transform-runtime不支持浏览器目标。插件转换运行时和预设环境可以独立工作。
