在terminal中输入clear后,提示:
The program 'clear' is currently not installed. You can install it
by typing:
sudo apt-get install ncurses-bin
按提示输入sudo apt-get install ncurses-bin后,系统却提示:
ncurses-bin is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
我查找了/usr/bin,里面的确没有clear,而libncurses5, libncurses5-dev,
libncursesw5都是安装了的。
解决方法:
sudo apt-get --reinstall install ncurses-bin
后记:
其实当时我想到了用reinstall,可惜在man apt-get的时候没耐心,草草看了一遍,居然没有找到--reinstall这个选项。在解决问题时,这种烦躁的心态要不得,否则即使能想到解决方式也会擦肩而过。
