CentOS yum install gcc 报错：glibc-common 与 glibc 冲突

Question

我在 CentOS 上安装 gcc 时遇到问题。

我的命令 sudo yum install gcc 的输出：

Loaded plugins: fastestmirror

 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

我不知道“冲突”是什么意思，在谷歌搜索后我什么也没找到。我怎样才能让 gcc 工作？

Answer 1

由于您的 CentOS 已经有一个不允许 glibc-common 安装自身和相关依赖项的 glibc 版本，因此会产生冲突。

运行rpm -qa | grep glibc并检查输出。

您可能会得到 2 个不同的版本，假设：

glibc-common-2.12-1.80.el6_3.5.x86_64
glibc-common-2.12-1.80.el6_3.4.x86_64

如果是，则删除 3.5 版本：

rpm -e glibc-common-2.12-1.80.el6_3.5.x86_64

之后，运行yum update并yum install gcc
