當我在 el6 上時，百勝嘗試安裝 el5

當我執行以下 yum 命令時，出現此錯誤：

Package: git-1.7.10.1-1.el5.rf.x86_64 (rpmforge)
          Requires: libcurl.so.3()(64bit)"

我讀到這個錯誤是由於執行 el5 rpmforge 或安裝了一些 el5 包。

我怎麼解決這個問題？

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

您可以使用yum repolist來顯示您啟用了哪些儲存庫，以及包的來源；

（另外yum repolist -v，帶有-v用於對啟用的儲存庫進行真正詳細描述的標誌）
