使用此链接,您可以重现该错误.

https://jsfiddle.net/pw7e2j3q/

<script>
$( "#test" ).change(function() {
  $("#test").remove();
  var combo = $("<select></select>").attr("id", "test2").attr("name", "test");
  combo.append("<option>New One</option>");
  $("#App").append(combo);
});

$("#click").click(function(){
  $("#App").remove();
})
</script>

如果单击某个<select>元素并将其从dom中删除,则在此之后单击链接测试.您应该看到旧<select>元素弹出以供选择.

是否有一些黑客来解决这个问题？

我有问题在heroku上安装这个包.有办法吗？

我看到这是canvas模块的问题,但我不知道该怎么做.

这是heroku上的安装日志.我不知道如何获得更多:
