我使用以下命令成功安装了ApiGen：
pear channel-discover pear.apigen.org
pear channel-discover pear.nette.org
pear channel-discover pear.texy.info
pear channel-discover pear.kukulich.cz
pear channel-discover pear.andrewsville.cz
pear install apigen/ApiGen
然后我跑了：
apigen -s /home/first.last/path/to/source/directory -d /home/first.last/path/to/destination/directory/
仅出现以下错误：
PHP Warning: require(Texy.php): failed to open stream: No such file or directory in /usr/bin/apigen on line 48
PHP Stack trace:

PHP 4. ApiGen\{closure}($class = 'Texy') /usr/bin/apigen:0

我跑的时候
locate Texy.php
我得到了:(很清楚它在那里）
/usr/share/pear/FSHL/Lexer/Texy.php
/usr/share/pear/FSHL/Lexer/Cache/Texy.php
/usr/share/pear/texy/src/Texy/Texy.php
