OSX 尝试安装自制程序时不遵守 PATH php

Question

我已经在 OSX high sierra 上安装了 homebrew-php php72。奇怪的是，当我运行 php 我仍然得到预安装的 php 7.1 - 更奇怪的是，当我运行 which php 它告诉我它将使用来自 /usr/local/bin 的自制版本不是 /usr/bin 中的预装版本。我没有设置别名。

一些shell输出：

$ echo $PATH
/usr/local/bin:/bin:/usr/bin:/usr/sbin:/sbin:/opt/X11/bin

$ which php
/usr/local/bin/php

$ php --version

$ alias | grep php # There are no aliases
$

$ type -a php
php is /usr/local/bin/php
php is /usr/bin/php

我想不出任何可能发生这种情况的原因？

谢谢 NFV

如命令中所述，hash -r 已修复该问题。来自 help hash:

  -r                forget all remembered locations

谨记：Why not use “which”? What to use then?
