網上看了下說是因為RPM數(shù)據(jù)庫出現(xiàn)損壞導致的，它導致所有的軟件的升級、安裝甚至是刪除都會出現(xiàn)問題，終端出現(xiàn)亂碼，YUMEX也用不成，RPM命令也用不成。按以下方法操作后，問題依舊：
$ su            切換到root權限
# rm -f /var/lib/rpm/__db.*    將rpm所用的數(shù)據(jù)庫刪除    ;這一步最好把_db.*備份一下
# rpm --rebuilddb     重建該數(shù)據(jù)庫
# yum clean all     清除YUM緩存

請問還有可能是哪里問題？

yum 出問題會導致 rpm 不能用？

看看你的python吧。。。yum是用python寫的。。。。如果你改變了python的環(huán)境，yum會出錯。。。


這個問題我之前遇到過

yum源配置和python環(huán)境我都沒動的，都不知是怎么回事，暈

無奈，最后是刪除然后重新安裝的yum包
