安装 env 命令

我想使用env，但 Ubuntu 告诉我它尚未安装。如果我尝试安装它，Ubuntu 会告诉我无事可做。如何解决这个问题？

$ env
The program 'env' is currently not installed. You can install it by typing:
sudo apt install coreutils

$ sudo apt install coreutils

coreutils is already the newest version (8.25-2ubuntu3~16.04).
0 upgraded, 0 newly installed, 0 to remove and 25 not upgraded.

$ env
The program 'env' is currently not installed. You can install it by typing:
sudo apt install coreutils

$ ls -l /usr/bin/env
ls: cannot access '/usr/bin/env': No such file or directory

如果确实丢失了，如输出所示ls，您可以使用命令重新安装 coreutils sudo apt-get install --reinstall coreutils。

这将简单地下载软件包并重新安装它，覆盖任何现有文件并创建任何缺失的文件。
