我通过将SVG形状组合到一条路径(没有任何其他svg对象的任何多边形)中解决了我的问题，然后将svg坐标传递到了fabircJS路径中.有效的SVG坐标看起来像是"M0,0H63.7V63.7H0Z"

I resolved my problem by combining the SVG shape into one path (without any polygons any other svg objects), then I pass the svg coords into fabircJS path. The valid SVG coords looks like that "M0,0H63.7V63.7H0Z"

fabric.loadSVGFromURL('object.svg', function (objects, options) {
            let img1 = new fabric.Path(objects[0].d, {
                fill: '#333',
                opacity: 1,
                hasBorders: true,
                hasControls: true,
                hasRotatingPoint: true,
                selectable: true,
                preserveObjectStacking: true,
                objectCaching: false,
            });
     }

我希望它会对其他人有所帮助:)
