我想创建一个线形成动画，所以我使用以下代码片段：
var lineDrawing = anime({
targets: '#path4136',
strokeDashoffset: [anime.setDashoffset, 0],
easing: 'easeInOutSine',
duration: 1500,
delay: function(el, i) { return i * 250 },
direction: 'alternate',
loop: true
});
我正在使用anime.js，我基本上复制了其中一个演示 HERE 的代码。
动画刚刚在我的演示中工作，我的意思是，这条线不会形成。
我做错了什么？
