Centos卸载gcc

(1)查看安装的gcc版本

[y@localhost Desktop]$ rpm -q gcc
gcc-4.4.7-23.el6.x86_64

(2)执行卸载命令 rpm -e

[y@localhost Desktop]$ rpm -e gcc-4.4.7-23.el6.x86_64
error: Failed dependencies:
    gcc = 4.4.7-23.el6 is needed by (installed) gcc-c++-4.4.7-23.el6.x86_64
    gcc = 4.4.4 is needed by (installed) libtool-2.2.6-15.5.el6.x86_64

提示gcc-4.4.7-23.el6.x86_64被2个软件依赖，卸载失败，则先卸载被依赖的软件包

sudo rpm -e gcc-c++-4.4.7-23.el6.x86_64
sudo rpm -e libtool-2.2.6-15.5.el6.x86_64

(4)再执行sudo rpm -e gcc-4.4.7-23.el6.x86_64进行卸载

sudo rpm -e gcc-4.4.7-23.el6.x86_64

卸载成功
(5) 验证，输入gcc -v

[y@localhost Desktop]$ gcc -v
bash: gcc: command not found

提示command not found，说明的确卸载成功了。
