带有网址的脚本标记仍捆绑在外部列表下

Question

我像这样（有条件地）加载了一个脚本，但是它最终出现在捆绑包中：

function loadScript(src) {
  if (isNode) return
  const xhrObj = new window.XMLHttpRequest()
  xhrObj.open('GET', src, false)
  xhrObj.send('')
  const se = window.document.createElement('script')
  se.type = 'text/javascript'
  se.text = xhrObj.responseText
  window.document.head.appendChild(se)
}

export default function () {
  // uses feature detection from polyfilll in quesiton
  if (globalSpace.Intl && globalSpace.Intl.DateTimeFormat
        && !globalSpace.Intl._DateTimeFormatTimeZone) { // eslint-disable-line no-underscore-dangle
    loadScript('https://unpkg.com/date-time-format-timezone@latest/build/browserified/date-time-format-timezone-complete-min.js')
  }
}

我更改了配置，指向绝对URL，因为根据应传递的文档-https://rollupjs.org/guide/en#big-list-of-options。

module.exports = (config) => {
  const { input, fileName, name } = config
  return {
    input: {
      input,
      external: [
        'dayjs',
        'https://unpkg.com/date-time-format-timezone@latest/build/browserified/date-time-format-timezone-complete-min.js'
      ],
      plugins: [
        babel({
          exclude: 'node_modules/**'
        }),
        uglify()
      ]
    },
    output: {
      file: fileName,
      format: 'umd',
      name: name || 'dayjs',
      globals: {
        dayjs: 'dayjs'
      }
    }
  }
}
