其实是报错有问题,实际上可能是你的context为null

export interface CanvasNode {
    getContext(type: '2d'): CanvasRenderingContext2D;

    width: number;
    height: number;
    _left: number;
    _top: number;
    // ... 其他方法和属性
}

export function canvasNode(canvasTag: string): Promise<CanvasNode> {
    return new Promise((resolve, reject) => {
        Taro.createSelectorQuery().select(canvasTag).node((ref) => {
            if (ref) {
                const canvas = ((ref as unknown as unknown[]).length > 0) ? ref[0].node : ref.node;
                if (canvas) {
                    console.log(`typeof canvas==>${Object.getPrototypeOf(canvas)}`)
                    resolve(canvas);
                } else {
                    reject(ref);
                }
            }
        }).exec();
    })
}
