vue-lazyload and vue-awesome-swiper are used in vue-cli. The scene is, open the broadcast picture, and then because the picture is large and the network is not good, a loading picture will be put on first, and the result will be like this (see the result first) 
 

loadingerrorsrc
 
 
// 
<img 
    data-src="http://localhost/slide/slowsexbanner.jpg" 
    data-loading="/lazyload/swiper-loading.png" 
    data-error="/lazyload/swiper-error.png" 
    alt="" 
    src="/lazyload/swiper-error.png"  //src
    lazy="error"
>
// src
<img 
    data-src="http://localhost/slide/201804301958.jpg" 
    data-loading="/lazyload/swiper-loading.png" 
    data-error="/lazyload/swiper-error.png" 
>
I have also tried to put the location where use () loads vue-lazyload behind other plug-ins, but the effect is the same, there is no way to solve it, ask for help from the bosses
