为什么这些图标没有出现在我的蚂蚁设计侧屏上？ [英] Why are the icons not showing up on my Ant Design sider?

问题描述

<Sider collapsible collapsed={this.state.collapsed} onCollapse={this.onCollapse} breakpoint="md">
          <Menu
          theme="dark"
          mode="inline"
          defaultSelectedKeys={['10']}
          style={{ lineHeight: '64px' }}
          >                            
          <Menu.Item key="2" icon={<LoginOutlined />}><Link to="/login">Login</Link></Menu.Item>

这是我的Sider代码的样子。但尽管如此，这一图标并没有显示在Sider上。这段代码在CodeSandBox上运行得很好。使用最新版本的Chrome。

即使是折叠的窗体也不显示图标。

请帮帮忙。
