致命错误：找不到类WP_Customize_Image_Control

我正在使用Windows 8.1 64位上的WAMP来开发自定义主题。

现在，我在尝试使用创建自定义控件时遇到以下错误WP_Customize_Image_Control 类别：

致命错误：未捕获错误：在C:\\wamp64\\www\\Ivana-5.2\\WP content\\themes\\Ivana\\inc\\Api\\Customizer\\WP\\u Customizer\\u Image\\u Control中找不到类“Ivana\\Api\\Customizer\\WP\\u Image\\u Control”。php第115行

错误：在C:\\wamp64\\www\\Ivana-5.2\\WP-content\\themes\\Ivana\\inc\\Api\\Customizer\\WP\\u Customizer\\u Image\\u-Control中找不到类“Ivana\\Api\\Customizer\\WP\\u-Image\\u-Control”。php第115行

我使用的是一种面向对象的设计，源于此入门主题：https://github.com/Alecaddd/awps

为什么WordPress无法找到WP_Customize_Image_Control 类，或任何此类类，就此而言？（也尝试了颜色和介质，但没有成功）。

如果您看到Customizer。php中，register方法调用\'customize_register\' 操作，安装程序收到$wp_customize.

如果不尝试使用自定义控件，这将非常有效。
