PHP -v 没有那个文件或目录

我已经在我的 PC 上安装了 PHP7.2，但是当我尝试安装时，php -v它显示了这样的错误

bash: /usr/local/bin/php: No such file or directory

然后我尝试输入php7.2 -v它的作品

有人有解决方案，所以当我输入 php -v 时它会显示 php7.2？

只需安装 php 替代包（https://packages.ubuntu.com/bionic/php）

sudo apt install php

你将获得新的符号链接

~$ ll /usr/bin/php7.2

~$ ll /usr/bin/php
lrwxrwxrwx 1 root root 21 Mar  7 17:05 /usr/bin/php -> /etc/alternatives/php*

~$ ll /etc/alternatives/php
