我是新来的匕首。因此，我无法解决这个问题。我只想在这里要求解决它。

这是错误：

不要用相同的名称类包装单身对象模块。更改您的模块文件或更改您的类名称

@Module
@InstallIn(SingletonComponent::class)
object ApiModule {
    
    @Provides
    @Singleton
    fun provideLoggingInterceptor(): HttpLoggingInterceptor {
        return HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY)
    }

    @Provides
    @Singleton
    fun provideOkHttpClient(logging: HttpLoggingInterceptor): OkHttpClient {
        return OkHttpClient.Builder()
            .addInterceptor(logging)
            .connectTimeout(15, TimeUnit.SECONDS) // connect timeout
            .readTimeout(15, TimeUnit.SECONDS)
            .build()
    }

    @Provides
    @Singleton
    fun provideRetrofit(client: OkHttpClient): Retrofit {
        return Retrofit.Builder()
            .baseUrl(ENDPOINT)
            .addConverterFactory(GsonConverterFactory.create())
            .client(client)
            .build()
    }

    @Provides
    @Singleton
    fun provideMovieAppService(retrofit: Retrofit): MovieAppService {
        return retrofit.create(MovieAppService::class.java)
    }
    
}
