如果这不是个好主意，请告诉我。

看起来是MarkerWithLabel的问题，而不是API本身的问题

如果我使用google.maps.Marker对象：

它起作用了

如果我使用与MarkerWithLabel相同的代码，它会出现javascript错误（

UncaughtTypeError:无法读取null的属性“x”

，

UncaughtTypeError:无法读取未定义的属性“k”），并且失败：

请提供一个，您的SVG图标是什么样子的？或者至少是一些可以显示效果的东西。@geocodezip，我现在把SVG（不是您的代码，因为它不完整，仍然不是最小值）放在您发布的代码中有语法错误（路径：car

后没有逗号）所以你的意思是我需要切换到google marker而不使用MarkerWithLabel？因为旋转问题？我不知道这是否是正确的想法，我通过在if语句的设置位置下放置新的MarkerWithLabel（markerarray[vehiclename[I]]）来解决它

 if (markerarray[vehiclename[i]] && markerarray[vehiclename[i]].setPosition){

              markerarray[vehiclename[i]].icon.rotation = parseInt(heading[i]);
              markerarray[vehiclename[i]].setPosition(newcoordinate);

      new MarkerWithLabel(markerarray[vehiclename[i]]);
