xml - 无法在 Ubuntu 12.04 上为 R 3.0.2 安装 XML 包

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。它已安装，但 R 找不到它的库!

正如我之前提到的，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 b/c 它是在 R 3.0 之前构建的。知道如何安装 XML 吗？它是非常重要的包，许多其他包都依赖于它。

谢谢，

凯汉

原来我的 Python Enthought 设置有冲突!!可能是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!
