Question

我正在使用角度应用程序，并且我在使用带有角度材料和bootstrap4的mdbbootstrap表单，我安装了两者，但是在编译时却出现了错误：模板解析错误mdb-card不是已知元素< / p>

我尝试添加模块...但是不起作用

<mdb-card>



  <!--Card content-->
  <mdb-card-body class="px-lg-5 pt-0">

    <!-- Form -->
    <form class="text-center" style="color: #757575;">

      <!-- Name -->
      <div class="md-form mt-3">
        <input type="text" id="materialContactFormName" class="form-control" mdbInput>
        <label for="materialContactFormName">Name</label>
      </div>

      <!-- E-mail -->
      <div class="md-form">
        <input type="email" id="materialContactFormEmail" class="form-control" mdbInput>
        <label for="materialContactFormEmail">E-mail</label>
      </div>

      <!-- Subject -->
      <span>Subject</span>
      <div class="row">
        <div class="col-md-12 mx-auto">
          <mdb-select [options]="optionsSelect" placeholder="Choose your option"></mdb-select>
        </div>
      </div>

      <!--Message-->
      <div class="md-form">
        <textarea type="text" id="materialContactFormMessage" class="form-control md-textarea" mdbInput></textarea>
        <label for="materialContactFormMessage">Message</label>
      </div>

      <!-- Copy -->
      <div class="row">
        <div class="col-md-6 mx-auto d-flex justify-content-center">
          <mdb-checkbox>Send me a copy of this message</mdb-checkbox>
        </div>
      </div>

      <!-- Send button -->
      <button mdbBtn color="info" outline="true" rounded="true" block="true" class="z-depth-0 my-4 waves-effect" mdbWavesEffect
        type="submit">Send</button>

    </form>
    <!-- Form -->

  </mdb-card-body>

</mdb-card>
