与RxPermission冲突

Question

我想在我的项目中使用tbruyelle RxPermissions库。我无法像这里一样调用subcribe方法

rxPermissions
    .request(Manifest.permission.ACCESS_FINE_LOCATION)
    .subscribe(granted -> {
        if (granted) {
           
        } else {
           
        }
    });

在方法“ request”上显示错误

Cannot access class 'io.reactivex.rxjava3.core.Observable'. Check your module classpath for missing or conflicting dependencies

我的build.gradle

repositories {
    //For YandexMap
    maven { url "http://maven.google.com/" }
    //For RxPermission
    maven { url 'https://jitpack.io' }
}
// rx - network

// rx
