安装包：
# sudo apt-get install ccache
但安装ccache有以下问题，搜到的解决方案不太敢尝试，怕把编译器搞崩了，暂存一下问题。
~$ sudo apt-get install ccache
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
ifenslave : Depends: ifupdown (>= 0.7.46)
liblxc1 : Depends: cgroup-lite but it is not going to be installed or
systemd
libpam-systemd : Depends: systemd (= 229-4ubuntu21.31)
resolvconf : Depends: ifupdown
snapd : Depends: systemd
systemd-sysv : PreDepends: systemd
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
~$ sudo apt-get -f install
