根据标题，在新的PHPUnit PEAR安装上运行phpunit -v会出现require_once失败错误。这里有一些额外的信息，我希望任何人都能帮助我。

检查依赖项
如果您最近升级到PHPUnit 3.6，则可能仍然安装了旧版本的File_Iterator，这就是问题所在（基于相同错误的模糊内存）。
您可以使用检查已安装软件包的版本
pear list -c pear.phpunit.de
如果有什么不对劲，或者只是为了确保升级PHPUnit以确保它是最新版本，所有依赖项也是如此：
$ pear update-channels
$ pear upgrade phpunit/PHPUnit
Did not download optional dependencies: phpunit/PHP_Invoker, use --alldeps to download automatically
phpunit/PHPUnit can optionally use package "phpunit/PHP_Invoker" (version >= 1.1.0)
phpunit/PHPUnit_MockObject can optionally use PHP extension "soap"

检查包含路径
如果您安装了合适版本的File_Iterator（和其他依赖项），但缺少File/Iterator/Autoload.php-它没有安装在php查找它的任何位置。使用pear list-files phpunit/File_Iterator可以查看pear认为文件的确切位置，并验证文件是否存在。
如果是这样，那么梨根就不在你的路径上，加上它，你就可以走了。
运行pear list -c pear.phpunit.de查看已安装的内容。
你应该看到这样的输出：
Installed packages, channel pear.phpunit.de:
============================================
Package Version State
File_Iterator 1.3.1 stable
PHPUnit 3.6.11 stable
PHPUnit_MockObject 1.1.1 stable
PHP_CodeCoverage 1.1.2 stable
PHP_Timer 1.0.2 stable
PHP_TokenStream 1.1.3 stable
Text_Template 1.1.1 stable
你可能（至少）错过了第一个。您可以浏览并安装每个依赖项，但更简单的方法是pear install -a pear.phpunit.de/PHPUnit。-a意味着获取所有依赖项，即使您已经安装了PHPUnit，它也能工作。在上面的系统上运行后，它将PHPUnit升级到3.6.12，还添加了PHP_Invoker，我似乎缺少它。
Installed packages, channel pear.phpunit.de:

注意：-a标志还具有可选的依赖项。如果你是一个极简主义者，这可能会困扰你：-）
