我最近按照文档中的指示使用pear包安装程序安装了PHPUnit。Pear当前安装在/usr/local/lib/php/pear中。但是，PHPUnit似乎将自己安装到/usr/share/pear中，因此当我尝试运行phpunit --version或phpunit --help时，我得到了包含错误。
我看到了三个可能的解决方案，但是我害怕如果我选错了，以后会遇到问题。以下是可能的解决方案:(A)将PHPUnit目录从/usr/share/pear/PHPUnit移动到/usr/local/lib/php/pear/PHPUnit， (B)将PHPUnit目录移动到/usr/local/lib/php/pear/share/pear/PHPUnit，或者(C)使用一些额外的命令或开关重新安装PHPUnit，以使其安装到正确的位置?
提前感谢您的帮助。

好了，看来我们找到问题了(见注释)。
我假设PHPUnit被安装为root或pear，由于某种原因拾取了"root"配置目录。
放置代码的路径定义在:
PEAR directory php_dir /usr/share/pear
所以pear配置中的某些东西似乎是问题。
如果可能的话，我将pear config-set php_dir $yourLocation，然后看看是否可行。
It is possible to install multiple versions of PHPUnit 使用pear install --installroot /some/path/，就像在帖子中描述的。所以无论如何都可以。
