如何在Ubuntu 12.04上安装libapache2-modxslt LTS

Question

我试图在Ubuntu 12.04 LTS上部署Symphony应用程序，并且在安装libapache2-modxslt时遇到问题。这是check_configuration.php的输出，你可以看到XSL模块没有安装。

********************************

    OK  php.ini has register_globals set to off 
    OK  php.ini has session.auto_start set to off 
    OK  PHP version is not 5.2.9 

我试图安装libapache2-modxslt时输入以下命令，这就是输出结果。

mark@ubuntu:/$ sudo apt-get install libapache2-modxslt php5-xsl

E: Unable to locate package libapache2-modxslt 

请指教。

Debian/Ubuntu软件包的名称稍有不同。它应该是libapache2-mod-xslt而不是libapache2-modxslt（注意“mod”和模块名称之间的短划线）。因此，尝试

sudo apt-get install libapache2-mod-xslt php5-xsl 

但，因为你需要XLS包PHP只，然后让包管理器找到正确的依赖本身（包管理做得很好，功能强大的Debian和衍生物作为Ubuntu的）。所以简单地做：

sudo apt-get install php5-xsl 

并让事情滚动。如果你好奇，你可以随时使用即apt-cache这样的列表软件包的依赖关系：

sudo apt-cache depends php5-xsl 

，但如果没有，你要安装需要一些额外的软件包，apt会让你知道，并要求确认安装额外的必需包。
