她要早点儿来见我的,但是没有出现。

她要早点儿来见我的,但是没有出现

She was going to meet me earlier,but she didn't show up

hadn't是过去完成时，一般都是与特定的时间点动词连用，表示过去的过去

比如：When the police arrived, the thieves had run away.

当警察赶到的时候，小偷已经跑了

这句话显然是thieves had run away发生在前，police arrived在后，因此要用过去完成时

你问的那句话不存在明确的时间先后问题，所以不用过去完成时

She must see me earlier, but has not appeared.

She need to see me earlier, but she wasn't there.

She must see me eary, but has not appeared.

ok. appeared 也行
