老师你好：
我在2-3 Jetpack Navigation 组件手把手实战（一） 这章按你的代码敲，
在TagsFragment哪里遇到编译报错：

package com.xm2013.jetpack_android_online.navigation

class TagsFragment : BaseFragment() {

//    lateinit var tagsBinding : LayoutFragmentTagsBinding
}

我开启了，重新运行了gradle, 还是编译不通，请问是什么原因？

    id("com.android.application")
    id("org.jetbrains.kotlin.android")
}

android {
    namespace = "com.xm2013.jetpack_android_online"

    defaultConfig {
        applicationId = "com.xm2013.jetpack_android_online"

        targetSdk = 33
