yum: gcc 試圖在 x86_64 伺服器上安裝 i686 架構

嘗試YUM install gcc gcc-g++ make並失敗：

但是， yum list --showduplicates glibc顯示的輸出：

Installed Packages
glibc.x86_64                   2.17-260.el7_6.3                   @anaconda/7.6 

並 yum list --showduplicates glibc-common顯示：

Installed Packages
glibc-common.x86_64               2.17-260.el7_6.3                @anaconda/7.6 

節目輸出的片段yum -v -y install gcc gcc-c++ make：

Package glibc.i686 0:2.17-260.el7 will be installed

為什麼 yum 會嘗試混合架構？如何強制 yum 僅安裝 x86_64 依賴項？

這個gcc包有點特別，因為它裡面的編譯器可以生成 32 位和 64 位庫。為此，它需要一些基本的 i686 系統庫（libgcc和glibc）。除了重新編譯編譯器以禁用 32 位支持之外，您無能為力。

你最好弄清楚為什麼glibc.i686無法安裝。看起來像版本不匹配，可能是由於 repos 的不兼容組合（您已安裝的el7_6.3版本glibc-common，但glibc.i686包需要el7）。
