如何在Ubuntu 12.04 LTS上安装libapache2-modxslt

Question

我试图在ubuntu 12.04 LTS上部署一个symphony应用程序，但在安装libapache2-modxslt时遇到问题。下面是check_configuration.php的输出，可以看到没有安装XSL模块。

我在尝试安装libapache2-modxslt时输入以下命令，输出如下所示。

mark@ubuntu:/$ sudo apt-get install libapache2-modxslt php5-xsl
Reading package lists... Done
Building dependency tree

E: Unable to locate package libapache2-modxslt

请给我建议。

Debian/Ubuntu包的命名略有不同。它应该是libapache2-mod-xslt而不是libapache2-modxslt (注意"mod“和模块名称之间的破折号)。所以试一试

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

而不是，既然你只需要XLSP包，那么就让包管理器自己找到正确的依赖项(包管理做得很好，在Debian和衍生工具上也很强大，比如Ubuntu)。所以，简单地这样做：

sudo apt-get install php5-xsl

让一切顺其自然吧。如果你很好奇，你可以像这样使用apt-cache列出包依赖关系：

sudo apt-cache depends php5-xsl

但是如果没有，并且你要安装的软件包需要额外的东西，apt会让你知道，并要求确认安装额外的所需软件包。
