"Failed to execute 'texImage2D' on 'WebGLRenderingContext"报这个错误是渲染模式的问题,应该把渲染模式转变为canvas就可以了
"renderMode" : 0,
// "renderMode" sets the renderer type, only useful on web :
// 0 - Automatically chosen by engine
// 1 - Forced to use canvas renderer
// 2 - Forced to use WebGL renderer, but this will be ignored on mobile browsers
修改project.json里面的renderMode参数
