Question

我无法在Ubuntu 12.04（64位）上的R 3.0.2上安装XML包（请参阅下面的错误）。我在网上搜索，我也安装了xml2-dev。它安装但R找不到它的库!!

正如我前面提到的，我已经安装了xml2：

sudo apt-get install libcurl4-openssl-dev libxml2-dev

kayhan@lemongrass:~$ locate libxml2.so
/usr/lib/x86_64-linux-gnu/libxml2.so.2
/usr/lib/x86_64-linux-gnu/libxml2.so.2.7.8

存储库中的“r-cran-xml”没有用，它是在R 3.0之前构建的。知道如何安装XML吗？许多其他包依赖它是非常必要的包。

谢谢，

原来我的Python Enthought设置有冲突！ Probaly因为它重载了一些库（通过修改LD_LIRARY）。在.bashrc中，我注释掉了：

VIRTUAL_ENV_DISABLE_PROMPT=1 source /[....]/Enthought/Canopy_64bit/User/bin/activate

并安装它，它的工作原理！奇怪的冲突！
