我正在使用CentOS 7 64位运行专用服务器,这是尝试安装IMAP时的输出：
yum install PHP-imap Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: ftp.ciril.fr * extras: ftp.ciril.fr * updates: ftp.ciril.fr No package PHP-imap available. Error: Nothing to do@H_301_3@禁用排除时也是如此：
sudo yum install --disableexcludes=all PHP-imap Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: ftp.ciril.fr * extras: ftp.ciril.fr * updates: ftp.ciril.fr No package PHP-imap available. Error: Nothing to do
