拖放bash的可执行文件位置哈希值

运行哈希phpunit

在/usr/bin/文件夹中有一个 phpunit 二进制文件(从错误消息中可以看出).

There was a phpunit binary in /usr/bin/ folder (as can be seen from the error message).

现在，它已被移至/usr/local/bin/.

但是bash会存储以前找到的可执行文件位置，并且不会立即对其进行更新，因此应清除旧的/usr/bin/phpunit 位置，以便找到新的可执行文件.

But bash stored the previously found locations of executables and doesn't update them immediately, so the old /usr/bin/phpunit location should be cleared for the new one to be found.
