我正在部署一个应用程序，该应用程序第一次在 Heroku 本地运行良好，但出现以下错误：

ModuleNotFoundError：没有名为“phonenumbers”的模块

想要使用下面的图表，但无法将标题颜色更改为白色，将轴和轴编号更改为灰色（或白色）。这应该高于深色背景。有人知道如何用echarts改变标题颜色吗？

<script type="text/javascript">
              // based on prepared DOM, initialize echarts instance
              var myChart = echarts.init(document.getElementById('main'));

              // specify chart configuration item and data
              var option = {
                  title: {
                      text: 'Total memebers of the club',
                      fontColor: 'white',
                      display: true,
                      position: 'bottom'

                  },
                  tooltip: {},
                  legend: {
                      data: ['Total member']
                  },
                  xAxis: {

                      data: ["11/2018", "12/2018", "01/2019", "02/2019", "03/2019", "04/2019"]
                  },
                  yAxis: {},
                  series: [{
                      itemStyle: {normal: {color: 'white'}},
                      name: 'Total',
                      type: 'bar',
                      data: [5, 384, 612, 2344, 4670, 9372]
                  }]

我希望在上传图片时使用 :hint 以立即在表单中显示它。我刚刚发现了该功能，但由于出现错误，似乎没有正确使用它。我正在寻找替换以下内容

<div class="input-group " style="width: 100% !important;">
  <span class="input-group-btn">
    <span class="btn btn-small btn-primary btn-inverse" onclick="$(this).parent().find('input[type=file]').click();">Browse</span>
      <%= f.file_field :avatar, onchange: "$(this).parent().parent().find('.form-control').html($(this).val().split(/[\\\\|/]/).pop());", style: "display: none;" %>
    </span>
    <span class="form-control"></span>
  </span>
 </div>

在以下形式中，使用 :hint

  <%= simple_form_for(resource, as: resource_name, url: registration_path(resource_name), html: {method: :put, multipart: true}) do |f| %>
     <%= f.error_notification %>
     <% if @user.avatar? %>
       <%= avatar_for(@user) %>
     <% else %>
       <%= image_tag("Avatar_default.jpg", alt: "No profile picture", width: "100%") %>
     <% end %>
     <br>
     <%=  f.input :avatar, :as => :file, :hint …
