因为手贱，yum -y remove ***，删了yum，重新安装的时候遇到了问题。

./yummain.py install yum Traceback (most recent call last): File "./yummain.py", line 27, in  from yum import Errors File "/home/huaxiaolong/yum-3.2.28/yum/__init__.py", line 42, in  import rpmsack File "/home/huaxiaolong/yum-3.2.28/yum/rpmsack.py", line 38, in  import yum.depsolve File "/home/huaxiaolong/yum-3.2.28/yum/depsolve.py", line 30, in  from transactioninfo import TransactionMember File "/home/huaxiaolong/yum-3.2.28/yum/transactioninfo.py", line 31, in  from sqlitesack import YumAvailablePackageSqlite File "/home/huaxiaolong/yum-3.2.28/yum/sqlitesack.py", line 26, in  import yumRepo File "/home/huaxiaolong/yum-3.2.28/yum/yumRepo.py", line 32, in  import sqlitecachec ImportError: No module named sqlitecachec

sqlitecachec这个模块需要安装哪个依赖包？网上查了很久都查不到。
