Any reproduce.

const routes = [
  {
    path: 'first',
    breadcrumbName: 'first:name',
    children: [
      {
          path: '/general',
          breadcrumbName: 'General',
      },
      {
          path: '/layout',
          breadcrumbName: 'Layout',
      },
      {
          path: '/navigation',
          breadcrumbName: 'Navigation',
      }
    ]
  }
];

<Breadcrumb routes={routes} params={{ name: '测试' }} />

在这种情形下渲染的

<a href="#/first">General</a>

路径应该是'#/first/general'
