Using MDBIcon throughout my project doesn't work.

import {
    MDBNavItem, MDBNavbar, MDBNavbarNav, MDBIcon,
    MDBBtn, MDBDropdownToggle, MDBDropdown,
    MDBAvatar, MDBDropdownMenu, MDBDropdownItem
} from "mdbreact";

<MDBNavItem>
    <div onClick={this.handleToggleClickA}
         key="sideNavToggleA"
         style={{
             lineHeight: "32px",
             marginRight: "1em",
             verticalAlign: "middle"
         }}
    >
        <MDBIcon icon="bars" color="white" size="2x"/>
    </div>
</MDBNavItem>

Do I need to install something else for the Icons to work?
