链接程序时出现WebGL错误

**更新**-我刚刚检查了它在Firefox中是否正常工作。确实如此。问题似乎在于Chromium如何处理WebGL。同样，请参阅下面的github链接。

我正在支持一个webgl/CV程序，当我注意到该网站开始从我没有接触过的代码中给出错误时。它抛出了一个错误，因为webgl程序没有正确链接。我觉得这很奇怪，因为当我最后一次接触这个项目的特定方面时（大约两个月前），它连接得很好。一些研究将我指向了这个链接：Github对问题的讨论

根据我的理解（如果我错了，请纠正我），有一个关于webgl如何处理不同类型变量的更新。我将发布着色器代码和使用它的函数，希望有人能指出一些我没有做过的测试。

this.createProgramObject = function(vetexShaderSource, fragmentShaderSource) {
        var vertexShaderObject = this.ctx.createShader(this.ctx.VERTEX_SHADER);
        this.ctx.shaderSource(vertexShaderObject, vetexShaderSource);
        this.ctx.compileShader(vertexShaderObject);
        if (!this.ctx.getShaderParameter(vertexShaderObject, this.ctx.COMPILE_STATUS)) {
            throw this.ctx.getShaderInfoLog(vertexShaderObject);
        }
        var fragmentShaderObject = this.ctx.createShader(this.ctx.FRAGMENT_SHADER);
        this.ctx.shaderSource(fragmentShaderObject, fragmentShaderSource);
        this.ctx.compileShader(fragmentShaderObject);
        if (!this.ctx.getShaderParameter(fragmentShaderObject, this.ctx.COMPILE_STATUS)) {
            throw this.ctx.getShaderInfoLog(fragmentShaderObject);
        }
        var programObject = this.ctx.createProgram();
        this.ctx.attachShader(programObject, vertexShaderObject);
        this.ctx.attachShader(programObject, fragmentShaderObject);
        this.ctx.linkProgram(programObject);
        if (!this.ctx.getProgramParameter(programObject, this.ctx.LINK_STATUS)) {
            throw ("Error linking shaders:" + this.ctx.getProgramInfoLog(programObject));
        }
        return programObject;
    };

在这个特定的调用中，函数使用point.vert和basic.frag.

点.vert

attribute vec3 aVertexPosition;
attribute vec4 aVertexColor;
uniform mat4 uModelViewMatrix;
uniform mat4 uProjectionMatrix;
uniform float uPointSize;
//for undetermined point attenuation feature
// uniform vec3 uAttenuation;
uniform vec3 uBias;
uniform vec3 uScale;
uniform int uCEMode;
varying vec4 vColor;
void main(void) {
    if(uCEMode == 1) {
        //use bias and scale unifroms for min max color enhancement
        vColor = (aVertexColor - vec4(uBias, 0.0)) * vec4(uScale, 1.0);
    }
    else {
        vColor = aVertexColor;
    }
    vec4 ecPos4 = uModelViewMatrix * vec4(aVertexPosition, 1.0);
    //make points larger as they get further away from the viewer
    //helps to make the cloud look less sparse when far enough to only see
    //the first level or two of the octree
    gl_PointSize = length(ecPos4) / uPointSize * 3.0;
    //for undetermined point attenuation feature
    // float attn = uAttenuation[0] + (uAttenuation[1] * dist) + (uAttenuation[2] * dist * dist);
    // gl_PointSize = (attn > 0.0 && attn < uPointSize) ? uPointSize * sqrt(1.0/attn) : uPointSize;
    gl_Position = uProjectionMatrix * ecPos4;
}

基本碎片

varying highp vec4 vColor;
void main(void) {
    gl_FragColor = vColor;
}

我能看到的vColor声明方式之间的唯一区别是highp说明符。如果我从basic.frag中删除它，它会显示"未捕获错误：0:1:''：没有为（float）指定精度"。如果我在point.vert中的声明中添加highp，则不会有任何变化。那么，我认为这个特定的说明符是好的。以下是Chrome中js控制台的错误消息：

Uncaught Error linking shaders:Varyings with the same name but different type, or statically used varyings in fragment shader are not declared in vertex shader: vColor
