空白项目在微信开发者工具端成功打开（没有压缩，压缩也会报错），后加了一些绘图api，报错如一楼图。添加绘图api代码如下
module laya {
    import Sprite = Laya.Sprite;
    import Stage = Laya.Stage;
    import WebGL = Laya.WebGL;

    export class Sprite_DrawShapes {
        private sp: Sprite;

        constructor()
        {
            // 不支持WebGL时自动切换至Canvas
            Laya.MiniAdpter.init();
            Laya.init(740, 400);

            Laya.stage.alignV = Stage.ALIGN_MIDDLE;
            Laya.stage.alignH = Stage.ALIGN_CENTER;

            Laya.stage.scaleMode = "showall";
            Laya.stage.bgColor = "#232628";

            this.drawSomething();
        }

        private drawSomething(): void {
            this.sp = new Sprite();
            Laya.stage.addChild(this.sp);
            //画线
            this.sp.graphics.drawLine(10, 58, 146, 58, "#ff0000", 3);
            //画连续直线
            this.sp.graphics.drawLines(176, 58, [0, 0, 39, -50, 78, 0, 117, 50, 156, 0], "#ff0000", 5);
            //画曲线
            this.sp.graphics.drawCurves(352, 58, [0, 0, 19, -100, 39, 0, 58, 100, 78, 0, 97, -100, 117, 0, 136, 100, 156, 0], "#ff0000", 5);
            //画矩形
            this.sp.graphics.drawRect(10, 166, 166, 90, "#ffff00");
            //画多边形
            this.sp.graphics.drawPoly(264, 166, [0, 0, 60, 0, 78.48, 57, 30, 93.48, -18.48, 57], "#ffff00");
            //画三角形
            this.sp.graphics.drawPoly(400, 166, [0, 100, 50, 0, 100, 100], "#ffff00");
            //画圆
            this.sp.graphics.drawCircle(98, 332, 50, "#00ffff");
            //画扇形
            this.sp.graphics.drawPie(240, 290, 100, 10, 60, "#00ffff");
            //绘制圆角矩形，自定义路径
            this.sp.graphics.drawPath(400, 310, [["moveTo", 5, 0], ["lineTo", 105, 0], ["arcTo", 110, 0, 110, 5, 5], ["lineTo", 110, 55], ["arcTo", 110, 60, 105, 60, 5], ["lineTo", 5, 60], ["arcTo", 0, 60, 0, 55, 5], ["lineTo", 0, 5], ["arcTo", 0, 0, 5, 0, 5], ["closePath"]], {fillStyle: "#00ffff"});
        }
    }
