angular - Ngx-Quill - 导入羊皮纸的问题

Question

我正在尝试基于此覆盖 Parchment - Quill 方法：

https://github.com/quilljs/quill/issues/409

class CustomColor extends Parchment.Attributor.Style {
  value(node) {
    let value = super.value(node);

    if (!value.startsWith('rgb(')) return value;

    value = value.replace(/^[^\d]+/, '').replace(/[^\d]+$/, '');

    return '#' + value.split(',').map(function(component) {
      return ('00' + parseInt(component, 10).toString(16)).slice(-2);
    }).join('');
  }
}

const customColorAttributor = new CustomColor('custom-color', 'color', {
    scope: Parchment.Scope.BLOCK,
});

Quill.register(customColorAttributor);

我仍然得到：

Cannot read properties of undefined (reading 'Attributor')

如何正确导入羊皮纸？
