我试过的

1.清除重建并使缓存重新启动和其他堆栈溢出应答无效这并没有解决我的问题

我也遵循了以下链接

我想知道如何解决异常。

看起来您试图在单独的模块中创建两个OkHttpClient实例。您可以对模块使用override parametr以替代一个实例
（模块（覆盖=true））
但在这种情况下，这是不正确的。您必须有两个不同的实例OkHttpClient。为此，可以使用命名实例
single<OkHttpClient>(named("WebService")) {
        createWebService<SportNewsInterface>(
            okHttpClient = createHttpClient(),
            factory = RxJava2CallAdapterFactory.create(),

        )
