我每次嘗試#sudo yum update時，都會收到PyYAML-3.08-4.el5.x86_64缺少依賴項的警告，libyaml-0.so.1（） （64位）。YUM在CentOS 5.8中抱怨PyYAML和libyaml
所以我做了一些檢查，看來libyaml確實已安裝，所以我想知道我的PyYAML和libyaml的安裝有什麼問題。 Pyyaml自動地提取了libyaml，這讓我認爲回購協議有些奇怪的事情發生。從YUM輸出如下：
[[email protected] ~]# yum update

You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
因此，我們知道我們有一個問題，所以這是哪裏libyaml呢？

那麼庫存在嗎？

64bit一個，32bit一個嗎？
[[email protected] ~]$ ls /usr/lib/libyaml-0.so.1*
/usr/lib/libyaml-0.so.1 /usr/lib/libyaml-0.so.1.1.0
它們都存在，所以有什麼問題？！？
