推荐答案
Range datepicker 使用了错误的 DateAdapter 范围策略.
Range datepicker uses range strategy with wrong DateAdapter.
为了修复它，您应该在您提供自定义 DateAdapter 的同一级别上提供 MAT_DATE_RANGE_SELECTION_STRATEGY 令牌:
In order to fix it you should provide MAT_DATE_RANGE_SELECTION_STRATEGY token on the same level where you provided custom DateAdapter:
import {
MAT_DATE_RANGE_SELECTION_STRATEGY,
DefaultMatCalendarRangeStrategy
} from '@angular/material/datepicker';
...
providers: [
{ provide: MAT_DATE_RANGE_SELECTION_STRATEGY, useClass: DefaultMatCalendarRangeStrategy},
{ provide: DateAdapter, useClass: MomentDateAdapter, deps: [MAT_DATE_LOCALE]},
....
它确保 DefaultMatCalendarRangeStrategy 类将 MomentDateAdapter 作为 DateAdapter 实现而不是 NativeDateAdapter
It makes sure that DefaultMatCalendarRangeStrategy class will get MomentDateAdapter as a DateAdapter implementation instead of NativeDateAdapter
