Unresolved reference: viewModels，viewModels()方法找不到

遇到的问题

最近在学习LiveData和ViewModel，跟着官网敲，碰到了以下情况

private val model: NameViewModel by viewModels()

这里的viewModels()爆红

已经添加的依赖如下

implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.3.0'
implementation 'androidx.lifecycle:lifecycle-livedata-ktx:2.3.0'

解决办法

再添加如下依赖即可

implementation "androidx.activity:activity-ktx:1.2.0"
implementation "androidx.fragment:fragment-ktx:1.3.0"
