install: missing destination file operand after 'man-pages' Try 'install --help' for more information.

`install: missing destination file operand after 'man-pages'`这个错误通常表示你在尝试安装man-pages文档时，缺少必要的目的地路径。man-pages是在Linux系统中提供命令手册页的软件包。

正确的命令应该是 `sudo apt-get install man-pages` 或者 `yum install man-pages`（取决于你的发行版，这里以apt-get为例），如果已经安装了基础包管理器，但仍然遇到这个问题，可能是因为权限不足或者man-pages已经被其他方式安装过，不在默认的软件源中。

下面是安装过程的一个简单示例：

1. 打开终端[^1]：

[root@VM_213_67_centos ~]# sudo apt-get update
[sudo] password for root: 
Hit:1 http://mirrors.aliyun.com/centos/7.9.2009/os/x86_64/ centos/7.9.2009/enobbld updates
